PEAK Achievement Guide: 100% Roadmap

PEAK sends up to four scouts up a procedurally generated mountain, and its 54 badges cover everything from simple biome progress to genuinely obscure item combinations that most players only learn about from a guide. Since the mountain regenerates daily and difficulty barely gates anything, most of this list comes down to knowing what to look for rather than raw skill. This guide covers every badge in unlock-rate order, with real strategies for the ones that don’t explain themselves.

Quick Stats

• Total Achievements: 54
• Estimated Completion Time: 20-30 hours
• Difficulty: 6/10
• Online Required: No (solo is possible, but several badges are far easier in co-op)
• Missable Achievements: None permanently; badges are tied to single-expedition conditions rather than a point of no return, so a bad run just means trying again

Achievements by Category (Detailed)

Biome Progress

Beachcomber Badge

Unlock Rate: 89.3% (Common)

Requirement: Climb past the SHORE.

How to Unlock: Reach the campfire at the top of the SHORE, the game’s first biome, and light it.

Tips: This is essentially unmissable, since it’s the first meaningful milestone in any run.

Trailblazer Badge

Unlock Rate: 63.4% (Common)

Requirement: Climb past the TROPICS.

How to Unlock: Reach the campfire at the top of the TROPICS, the second biome, and light it.

Tips: Watch for ticks in this biome, since they can cause slow poison damage if you’re not paying attention while climbing.

Volcanology Badge

Unlock Rate: 48.8% (Uncommon)

Requirement: Climb past the CALDERA.

How to Unlock: Reach and light the campfire at the top of the CALDERA biome.

Tips: Bring marshmallows and take your time here, since CALDERA marks a significant midpoint before the mountain gets considerably harder.

Alpinist Badge

Unlock Rate: 43.6% (Uncommon)

Requirement: Climb past the ALPINE.

How to Unlock: Reach the campfire at the top of the ALPINE, the third biome, and light it.

Tips: Bring a lantern to help manage the Cold status here, since ALPINE’s temperature drop is a common source of unconsciousness.

Nomad Badge

Unlock Rate: 34.3% (Uncommon)

Requirement: Climb past the MESA.

How to Unlock: Reach and light the campfire at the top of the MESA biome.

Tips: MESA is also home to the Scout Cannon needed for the Daredevil Badge, so consider working on both in the same run.

Forestry Badge

Unlock Rate: 26.4% (Rare)

Requirement: Climb past the ROOTS.

How to Unlock: Reach the top of the ROOTS biome, introduced in a later content update, and progress past it.

Tips: ROOTS introduces mushroom mechanics tied to several newer badges like Mycoacrobatics, so this is a good biome to explore thoroughly rather than rushing through.

Peak Badge

Unlock Rate: 32.1% (Uncommon)

Requirement: Reach the PEAK.

How to Unlock: Survive THE KILN biome and reach the final zone, PEAK, at the top of the mountain.

Tips: This unlocks after the fifth zone, THE KILN, once you reach the sixth and final zone, so treat it as your primary end-goal for a full expedition.

Exploration & Items

Esoterica Badge

Unlock Rate: 72.4% (Common)

Requirement: Obtain a mystical item.

How to Unlock: Complete a biome without any deaths, then interact with the Effigy Statue at the end of that biome to receive a mystical item. In multiplayer, if a teammate died during that biome, activating the statue revives them instead of granting the item.

Tips: Since a teammate death converts this into a revive instead, aim for this badge specifically on biomes where your whole team survived cleanly.

Arborist Badge

Unlock Rate: 31.5% (Uncommon)

Requirement: Reach the top of a really big tree.

How to Unlock: In the TROPICS biome, locate and climb a giant tree to its top.

Tips: The giant tree is a distinct landmark separate from the main climbing path, so keep an eye out for it while exploring TROPICS rather than sticking strictly to the direct route.

Bookworm Badge

Unlock Rate: 9.0% (Very Rare)

Requirement: Read the Scoutmaster’s final journal entry.

How to Unlock: Collect all 8 Scoutmaster Myres journal pages, found as scrolls near campfires across SHORE, TROPICS, ALPINE, and CALDERA. Open a scroll in the biome matching its page number to get the next page in sequence, and check your progress count in the achievement description as you go.

Tips: Pages must be read in chronological order (1 through 8), so if you find a scroll for a page you don’t need yet, carry it to a later biome instead of opening it immediately. If you can’t find any pages, the map resets daily, so try again on a new expedition.

Astronomy Badge

Unlock Rate: 7.2% (Very Rare)

Requirement: Look a little too closely at the blazing sun.

How to Unlock: In the MESA biome, use Binoculars to look directly at the sun.

Tips: Binoculars need to spawn in your run for this to be possible, so check luggage in MESA for them if you don’t already have a pair.

Endurance Badge

Unlock Rate: 26.3% (Rare)

Requirement: Climb 50m upwards without touching the ground.

How to Unlock: Climb continuously upward for 50 meters without your character touching flat ground at any point during that climb.

Tips: Vertical rock faces and cliffs work best for this, since flatter terrain breaks the streak even briefly.

High Altitude Badge

Unlock Rate: 47.8% (Uncommon)

Requirement: Climb 5000m total.

How to Unlock: Accumulate 5,000 meters of total climbing distance across any number of expeditions; this is a lifetime total, not a single-run requirement.

Tips: This adds up naturally over multiple playthroughs, so don’t feel pressure to rush it in one session.

Food & Foraging

Foraging Badge

Unlock Rate: 35.1% (Uncommon)

Requirement: Eat 5 different berries in a single expedition.

How to Unlock: Find and eat 5 distinct berry types during one expedition, without dying or restarting in between.

Tips: Different biomes host different berry types, so this is easier on longer runs that pass through multiple zones.

Cooking Badge

Unlock Rate: 35.5% (Uncommon)

Requirement: Cook 20 meals at campfires.

How to Unlock: Prepare 20 units of any cooked food using campfires. The crashed plane’s wing at the very start of the game has a persistent fire source, useful for breaking coconuts and cooking food early.

Tips: This is a lifetime total across runs, so it accumulates naturally if you cook food regularly rather than eating things raw.

Mycology Badge

Unlock Rate: 8.8% (Very Rare)

Requirement: Eat four different non-toxic mushrooms in a single expedition.

How to Unlock: In the ROOTS biome, find and eat 4 distinct non-toxic mushroom types within one expedition.

Tips: Learn to distinguish toxic from non-toxic mushrooms before attempting this, since eating the wrong type wastes an attempt and can cause status damage.

Gourmand Badge

Unlock Rate: 4.6% (Ultra Rare)

Requirement: Escape the island after cooking and eating a coconut half, a honeycomb, a yellow winterberry, and an egg.

How to Unlock: Find a Half-Coconut (SHORE), Honeycomb (TROPICS beehives), Yellow Winterberry (ALPINE or CALDERA), and Egg (CALDERA bird nests), cook each one at a Portable Stove, eat all four, then successfully escape the island in that same expedition.

Tips: Plan your foraging route around these four biomes in advance, since finding all four ingredients requires deliberate detours rather than incidental pickups.

Advanced Mycology Badge

Unlock Rate: 4.4% (Ultra Rare)

Requirement: Try all 5 types of Shroomberry in a single expedition.

How to Unlock: In the ROOTS biome, find and eat all 5 Shroomberry variants within one expedition.

Tips: This builds directly on the same ROOTS foraging skills needed for Mycology, so attempt both in the same dedicated run.

Cryptogastronomy Badge

Unlock Rate: 2.5% (Ultra Rare)

Requirement: Cook and eat a Mandrake.

How to Unlock: Find a Mandrake in the ROOTS biome, which can randomly spawn in place of any Medicinal Root. You need a Portable Stove to cook it immediately, since an uncooked Mandrake’s screams will stun-lock you and can kill you before you can eat it.

Tips: If you don’t have a Portable Stove, use a Book of Bones to turn into a skeleton first, since skeletons don’t take the Mandrake’s sleep-based stun damage.

Competitive Eating Badge

Unlock Rate: 3.5% (Ultra Rare)

Requirement: Eat 3 Hot Dogs in 5 seconds or less.

How to Unlock: Find and eat 3 Hot Dog items in rapid succession, within a 5-second window.

Tips: Stack all 3 Hot Dogs in your quickslots beforehand so you can eat them back to back without fumbling through your inventory.

Naturalist Badge

Unlock Rate: 7.8% (Very Rare)

Requirement: Escape the island without eating any packaged food.

How to Unlock: Complete a full expedition and escape without ever eating packaged food items like lollipops, energy drinks, or survival bars.

Tips: Stick entirely to foraged and cooked natural food for the whole run, since a single packaged food item invalidates the attempt.

Resourcefulness Badge

Unlock Rate: 6.1% (Very Rare)

Requirement: Give in to your hunger.

How to Unlock: Let your hunger meter deplete fully and suffer the consequences of starvation rather than eating in time.

Tips: This is a deliberately grim achievement; simply avoid eating when your character’s hunger bar bottoms out to trigger it.

Support & Co-op

First Aid Badge

Unlock Rate: 41.9% (Uncommon)

Requirement: Heal your friends for 100 points of injury in a single expedition.

How to Unlock: Using healing items or abilities, heal teammates for a cumulative 100 injury points within one expedition.

Tips: This requires a co-op group, so dedicate one run to playing a support-focused role with healing items on hand.

Emergency Preparedness Badge

Unlock Rate: 29.4% (Rare)

Requirement: Heal an unconscious friend with an item to save them from death.

How to Unlock: Use a healing item on a teammate who has fallen unconscious, reviving them before they die.

Tips: Keep healing items on hand at all times when playing in a group, since you won’t know in advance when a teammate goes down.

Clutch Badge

Unlock Rate: 20.1% (Rare)

Requirement: Resurrect 3 scouts in a single expedition.

How to Unlock: Revive 3 different teammates who have become full ghosts (not just unconscious) within one expedition.

Tips: This requires actual deaths to occur among your team, so it’s easiest during a chaotic or higher-difficulty run with a full group.

Participation Badge

Unlock Rate: 26.2% (Rare)

Requirement: Have a friend escape the island without you.

How to Unlock: Die or become a ghost during an expedition, then have at least one teammate successfully escape the island while you remain behind.

Tips: This is one of the least effort-intensive badges in the game, since dying and letting your team finish without you is all it takes.

Happy Camper Badge

Unlock Rate: 58.8% (Common)

Requirement: Receive 5 Morale Boosts from campfires.

How to Unlock: Stand near a lit campfire with teammates to receive Morale Boosts, accumulating 5 total. THE KILN and PEAK biomes don’t have campfires, so this needs to happen in earlier zones.

Tips: This requires a multiplayer group, since Morale Boosts are a shared buff mechanic. Stay close to the fire, since the warmth and morale effect doesn’t extend far.

Mentorship Badge

Unlock Rate: 21.0% (Rare)

Requirement: Have a 1-on-1 with the Scoutmaster.

How to Unlock: In a solo expedition, use the Scoutmaster’s Bugle to summon the Scoutmaster and interact with them one-on-one.

Tips: This ties closely to the Lone Wolf Badge, since both require a solo run; consider working on them together.

Disaster Response Badge

Unlock Rate: 2.8% (Ultra Rare)

Requirement: Pull an unconscious friend 30m with the Rescue Claw.

How to Unlock: Find the Rescue Claw item and use it to drag an unconscious teammate a full 30 meters.

Tips: You’ll need the Rescue Claw to spawn in your run’s luggage, and a willing teammate to go unconscious (or wait for a natural knockout) to attempt this.

Applied Esoterica Badge

Unlock Rate: 2.3% (Ultra Rare)

Requirement: Resurrect a friend using unholy means.

How to Unlock: Use a specific dark or unconventional revival method, distinct from standard revival items, to bring back a dead teammate.

Tips: This is one of the more obscure badges in the game, tied to a specific item or ritual most players only learn about from a guide rather than organic discovery.

Survival Conditions

Survivalist Badge

Unlock Rate: 17.9% (Rare)

Requirement: Escape the island without ever losing consciousness.

How to Unlock: Complete a full expedition and escape without ever falling unconscious from accumulated negative afflictions.

Tips: You get about 5 seconds of blurred, slowed vision as a warning before a full knockout, so use that window to remove negative afflictions immediately. Bring a lantern into ALPINE specifically, since Cold is one of the most common causes of unconsciousness.

Toxicology Badge

Unlock Rate: 13.8% (Very Rare)

Requirement: Restore 200 total poison by using items.

How to Unlock: Use items like Medicinal Root, Antidote, or Cure-Alls to cumulatively cure 200 points of poison across any number of expeditions.

Tips: Deliberately eating something toxic and then curing it repeatedly is a viable way to farm this, rather than only relying on incidental poison from the environment.

Cool Cucumber Badge

Unlock Rate: 12.3% (Very Rare)

Requirement: Climb past the MESA without ever having more than 10% Heat.

How to Unlock: Progress through the entire MESA biome while keeping your Heat status meter below 10% at all times.

Tips: Stick to shaded routes and use cooling items proactively rather than reactively, since MESA’s heat buildup is constant and unforgiving.

Bundled Up Badge

Unlock Rate: 6.1% (Very Rare)

Requirement: Climb past the ALPINE without ever having more than 20% Cold.

How to Unlock: Progress through the entire ALPINE biome while keeping your Cold status meter below 20% at all times.

Tips: Bring a lantern and warm clothing items into ALPINE, and consider attempting this on Tenderfoot difficulty, since slower hazard damage gives more reaction time to manage your Cold meter.

Tread Lightly Badge

Unlock Rate: 14.7% (Very Rare)

Requirement: Climb past the ROOTS without ever having more than 25% spores.

How to Unlock: Progress through the entire ROOTS biome while keeping your Spores status meter below 25% at all times.

Tips: Avoid unnecessary contact with spore-releasing mushrooms and fungal terrain while climbing through this biome.

Undead Encounter Badge

Unlock Rate: 11.6% (Very Rare)

Requirement: Cure yourself from a zombie bite.

How to Unlock: Get bitten by a zombie enemy, then cure the resulting bite status before your Spores stat reaches zero. This achievement cannot be earned on Tenderfoot difficulty.

Tips: This is the only badge in the game confirmed to have a difficulty restriction, so make sure you’re playing on Normal or higher before attempting it.

Web Security Badge

Unlock Rate: 22.1% (Rare)

Requirement: Escape a spider’s web and survive.

How to Unlock: Get caught in a spider’s web, then escape it and survive the encounter.

Tips: Struggle free as soon as you’re caught rather than waiting, since surviving the encounter is the actual requirement, not just escaping the web itself.

Megaentomology Badge

Unlock Rate: 6.2% (Very Rare)

Requirement: Survive an Antlion attack.

How to Unlock: Encounter an Antlion enemy, get attacked, and survive the encounter.

Tips: Antlions are one of the more dangerous creature encounters in the game, so approach any Antlion sighting with full health and healing items ready.

Needlepoint Badge

Unlock Rate: 4.7% (Ultra Rare)

Requirement: Have a lot of cactuses stuck to you.

How to Unlock: Accumulate a large number of cactus spines stuck in your character, typically by falling into or brushing against cacti repeatedly.

Tips: This is largely accidental for most players, but deliberately rolling through cactus patches can trigger it faster than waiting for natural encounters.

Solo & Speed Challenges

Lone Wolf Badge

Unlock Rate: 10.1% (Very Rare)

Requirement: Escape the island in a solo expedition.

How to Unlock: Start and complete an entire expedition by yourself, with no other players in your session, and successfully escape.

Tips: If playing as the host with a group nearby, separating 200-500 meters from your squad and having no one wait around can also register as a solo run for this achievement.

Speed Climber Badge

Unlock Rate: 8.7% (Very Rare)

Requirement: Escape the island in under an hour.

How to Unlock: Complete a full expedition and escape within 60 in-game minutes of starting.

Tips: Practice a known route in advance and load up on supplies quickly at the start, since hesitation early in the run eats into your time budget the most.

Balloon Badge

Unlock Rate: 7.4% (Very Rare)

Requirement: Escape the island without taking fall damage.

How to Unlock: Complete a full expedition and escape without taking any fall damage at any point.

Tips: Use ropes and pitons consistently rather than free-climbing risky sections, and never rush a descent, since a single bad fall invalidates the whole run.

Leave No Trace Badge

Unlock Rate: 5.4% (Very Rare)

Requirement: Escape the island without placing anything on the mountain.

How to Unlock: Complete a full expedition and escape without placing any pitons, chains, or ropes. Magic Beans and Shelf Fungus are exceptions and can be used normally without breaking this condition.

Tips: Plan your climbing route around natural terrain features in advance, since this removes your usual traversal tools for the entire run.

Movement & Traversal

Daredevil Badge

Unlock Rate: 10.0% (Very Rare)

Requirement: Shoot across the MESA canyon in a Scout Cannon.

How to Unlock: Find the Scout Cannon in MESA and use it to launch yourself across the biome’s canyon, roughly midway through the flat portion of the map.

Tips: Some players have reported unlocking this using a Chain Launcher instead of the Scout Cannon, so if you have one available it may work as an alternative.

Aeronautics Badge

Unlock Rate: 9.0% (Very Rare)

Requirement: Achieve flight.

How to Unlock: Collect 6 Balloons in a single run and attach all of them to yourself to achieve sustained flight.

Tips: Balloons need to spawn across your run, so keep an eye out for them in multiple biomes rather than expecting to find all 6 in one area.

Mycoacrobatics Badge

Unlock Rate: 8.0% (Very Rare)

Requirement: Bounce up 40m off a mushroom.

How to Unlock: In the ROOTS biome, find a bounce mushroom and use it to launch yourself 40 meters upward in a single bounce.

Tips: Look for the largest bounce mushrooms you can find, since bounce height typically scales with the mushroom’s size.

Ultimate Badge

Unlock Rate: 6.5% (Very Rare)

Requirement: Catch a Flying Disc from 100m away.

How to Unlock: Find a Flying Disc item and successfully catch one thrown from 100 meters away.

Tips: This requires a co-op teammate to throw the disc from the correct distance, so coordinate the throw and catch deliberately rather than hoping for a lucky toss.

Bouldering Badge

Unlock Rate: 11.6% (Very Rare)

Requirement: Place 10 pitons.

How to Unlock: Place 10 pitons into the mountain’s surface at any point across any number of runs.

Tips: This is a lifetime total with no special conditions, so it accumulates naturally through normal climbing if you use pitons regularly.

Knot Tying Badge

Unlock Rate: 3.7% (Ultra Rare)

Requirement: Place 100m of rope in a single expedition.

How to Unlock: Within one expedition, place a cumulative 100 meters of rope. Rope Cannons count toward this total, as does any rope length, including short segments.

Tips: Use Rope Cannons liberally throughout a single run rather than sparingly, since every meter placed counts toward the total regardless of length.

Special & Story

Bing Bong Badge

Unlock Rate: 15.7% (Rare)

Requirement: Help Bing Bong escape the island.

How to Unlock: Bing Bong spawns in the crashed plane at the start of the game. Carry him in your inventory all the way to PEAK and escape via helicopter with him still in your inventory.

Tips: In multiplayer, only one player needs to carry Bing Bong to the helicopter for the whole team to receive the badge, so coordinate who’s responsible for protecting him throughout the run.

Animal Serenading Badge

Unlock Rate: 15.0% (Rare)

Requirement: Play the bugle for a capybara.

How to Unlock: Find a bugle item and a capybara, both found in the ALPINE or MESA biomes, then play the bugle while near the capybara.

Tips: Capybaras and bugles don’t spawn in every run, so check a daily seed report if you’re specifically hunting for this badge and neither has appeared yet.

24 Karat Badge

Unlock Rate: 4.7% (Ultra Rare)

Requirement: Offer The Kiln a worthy sacrifice.

How to Unlock: Find the Golden Bing Bong (a rare variant found in the MESA biome, sometimes called the Ancient Idol), carry it all the way to THE KILN, and throw it into the lava.

Tips: The Golden Bing Bong can be incinerated by walking across lava or hot surfaces while holding it and still trigger the achievement, so you can take a faster but riskier route to THE KILN if needed. A full team can help share the item’s weight penalty across the climb.

Plunderer Badge

Unlock Rate: 38.0% (Uncommon)

Requirement: Open 15 luggages in a single expedition.

How to Unlock: Open 15 pieces of luggage of any type within one expedition.

Tips: This adds up quickly if you’re thorough about looting every luggage box you encounter rather than skipping ones that look empty.

Calcium Intake Badge

Unlock Rate: 9.3% (Very Rare)

Requirement: Block 100 total damage with the Fortified Milk.

How to Unlock: Drink Fortified Milk to gain its damage-blocking buff, and use it to absorb a cumulative 100 damage across any number of uses.

Tips: Fortified Milk needs to spawn in your run’s luggage, so prioritize picking it up when you see it if you’re working toward this badge.

5-Phase 100% Completion Roadmap

Phase 1: Biome Progress and Basics Play through normal expeditions focused on reaching each biome’s campfire in sequence: SHORE, TROPICS, ALPINE, MESA, CALDERA, and eventually ROOTS and PEAK. This naturally unlocks Beachcomber, Trailblazer, Alpinist, Nomad, Volcanology, Forestry, and Peak Badges, along with easy passive badges like Cooking, Plunderer, and High Altitude.

P2: Co-op Support Runs Organize dedicated group sessions to farm First Aid, Emergency Preparedness, Clutch, Participation, Happy Camper, and Mentorship Badges. These are much faster with a coordinated team than solo play, since several require actual teammate deaths or downs to trigger.

P3: Food and Foraging Focus Dedicate a run or two to foraging-heavy badges: Foraging, Mycology, Advanced Mycology, Gourmand, and the higher-risk Cryptogastronomy Badge (bring a Portable Stove or Book of Bones before attempting the Mandrake).

P4: Condition and Speed Challenges Attempt the “without ever having more than X%” survival badges (Cool Cucumber, Bundled Up, Tread Lightly) and the no-item runs (Balloon, Leave No Trace, Naturalist, Survivalist) as dedicated, carefully planned expeditions rather than incidental attempts. Pair Speed Climber with these runs where possible for efficiency.

P5: Rare Item and Story Cleanup Finish with the rarest badges: Bing Bong, 24 Karat, Bookworm (collecting all 8 journal pages in order), and the movement-based badges like Aeronautics, Mycoacrobatics, and Daredevil. Check daily seed reports for runs where specific rare items like Bugles, Capybaras, or the Golden Bing Bong have spawned.

Conclusion

PEAK’s badge list rewards patience and planning more than raw climbing skill. The biome-progress badges come for free just by playing normally, but the rarest ones (Bing Bong, 24 Karat, Cryptogastronomy) hinge on knowing exactly what to look for and where, since none of them are hinted at clearly in-game. Play with a coordinated group for the support and co-op badges, plan dedicated runs around the “without ever” survival conditions, and treat rare item spawns as something to check for via daily seed information rather than pure luck.
