PEAK throws six wildly different environments at your climbing team as you ascend from sea level to the summit. Each biome has its own hazards, its own gear requirements, and its own survival rules — and unlike most climbing games, PEAK doesn’t give you a tutorial. You learn the hard way what the Tropics does to your stamina in the rain, what happens when an Alpine blizzard rolls in while you’re mid-wall, and why the Mesa’s canyon crossing is the run-ending moment that filters out unprepared teams.
This guide covers every PEAK biome in climb order. For each zone you’ll find the standout hazard, the gear you need to carry before entering, key survival tactics, and where to find food to top off your stamina. If you haven’t started your first run yet, read through our PEAK beginners guide first — this biome breakdown assumes you understand the basic climbing mechanics and inventory system.
All Six PEAK Biomes at a Glance
PEAK’s mountain is divided into six distinct biomes arranged in a fixed vertical order. Every run passes through all six. There is no skipping, no alternative route past a biome, and no going back once you’ve ascended through one. The difficulty and gear requirements escalate sharply — a team that breezes through the Shore and Tropics can be completely destroyed by Alpine if they arrive without hand warmers.
| Biome | Primary Hazard | Essential Gear | Key Food |
|---|---|---|---|
| Shore | None significant | Pitons, rope cannon ammo | Coconuts |
| Tropics | Rain, slippery surfaces, exploding bushes | Steady footwear, awareness | Shroomberries |
| Alpine | Blizzards, icy grips | Hand warmers (non-negotiable) | Stock up before entry |
| Mesa | Blistering sun stamina drain | Route planning, shade awareness | Limited — plan ahead |
| Caldera | Rising lava, fire AoE | Speed, pre-planned route | None — pure movement |
| Kiln | Stamina depletion, darkness | Full stamina entering | Consume everything before entry |
Shore: Build Your Foundation Here
The Shore is where every PEAK run begins, and its forgiving terrain makes it easy to underestimate. Gentle sandy slopes, flat beaches, and a complete absence of meaningful environmental hazards mean you can move freely and explore without your stamina bar under threat. Do not waste that freedom. The Shore is the only biome in PEAK where you can gather resources, set anchors, and load your inventory without any external pressure.
Hazards
The Shore has no significant environmental hazards. The initial slopes are manageable without specialist gear, weather is clear, and the terrain is predictable. The only threat at this stage is player error — falling from the first slopes without a respawn anchor set will send you back to the beach. It won’t end your run, but it costs precious time.
Essential Gear
The Shore is where you collect rope cannon ammo from ground caches scattered across the beach and lower slopes. These caches are easy to miss if you rush straight for the climb, so sweep the area before ascending. Rope cannon ammo is a limited resource and you’ll want as much as possible before the Tropics. Also stock your pitons here — set the first respawn anchors on the initial slopes as soon as you start ascending. Losing progress to a piton-free fall early stings more than it should.
Survival Tips
- Sweep the entire beach before climbing. Ground caches here contain rope cannon ammo, basic gear, and occasionally food.
- Set a piton anchor at the first significant ledge — this becomes your respawn fallback for the rest of the Shore section.
- Coordinate with your team before leaving the beach. Make sure everyone has at least a few pitons and knows where their rope cannon ammo is stored.
- The Shore transition into the Tropics is gradual, but once the rain starts you’re in Tropics territory. Watch for it.
Food Sources
Coconuts are the Shore’s key food item and one of the most reliable stamina sources in the early game. Gather every coconut you can carry. Cook them before ascending if you have a cooking station available — cooked coconuts restore more stamina than raw ones. Carrying a surplus of cooked coconuts into the Tropics gives your team a significant buffer against the stamina drain from wet surfaces and exploding bush incidents.
Tropics: Rain, Slippage, and Hidden Explosives
The Tropics is where PEAK first tests your team coordination. Intermittent rain is the defining feature of this biome — it cycles on and off rather than falling constantly, but when it’s raining, every surface becomes slippery and stamina drains slightly faster. The bigger threat, though, is something entirely different: exploding bushes scattered across the terrain that nobody tells you about before you walk into one.
Hazards
Rain is the ambient challenge of the Tropics. Wet surfaces reduce grip on slopes and walls, making moves you’d nail in the Shore feel unreliable. Stamina burn is slightly higher in wet conditions, which matters when you’re carrying a full inventory and pushing toward the Alpine transition.
Exploding bushes are the Tropics’ signature ambush. These bushes look like ordinary vegetation until they detonate. They trigger if a player falls onto one from above, or if the team clusters too close together near a bush. In a co-op group where players are roped together and moving in tight formation, a single detonation can chain-stagger the entire team. The explosion itself deals stamina damage and can knock players off ledges. Always identify bushes before you approach them and route around them where possible. If you need to climb past a bush cluster, send players through one at a time with enough gap that a single detonation can’t reach the whole team.
Essential Gear
No specialist gear is specifically required for the Tropics, but arriving with cooked coconuts from the Shore gives you stamina redundancy for the rain-draining sections. Rope cannon ammo is useful here for creating traversal shortcuts around bush-heavy sections. Check the terrain for shroomberry patches before climbing through them blindly.
Survival Tips
- During rain, slow down on exposed slopes. The stamina cost of a fall-recover here is worse than the time saved by rushing.
- Scan ahead for exploding bushes before descending or jumping. They often cluster near ledges and transition points.
- Space out the team when passing through bush-heavy areas. A team of four walking in a line through a bush cluster is asking for a chain detonation.
- The Tropics is wetter at higher elevations within the biome. Budget more stamina for the upper section than the lower.
Food Sources
Shroomberries grow throughout the Tropics and are worth gathering, but identify the color before eating. Different shroomberry colors have different effects — some restore stamina normally, others apply debuffs. As a rule, stick to the colors your team has confirmed are safe from previous runs, and leave unidentified colors alone unless you’re desperate.
Alpine: The Biome That Ends Unprepared Runs
The Alpine biome is where PEAK runs die. Not because it is impossible, but because teams that reach it underprepared face a wall of stamina drain they cannot recover from. Cold air, icy wall surfaces, and sudden blizzards combine to punish every inefficiency in your loadout and movement. Alpine is not where you learn that you needed hand warmers. Alpine is where you either have them or you turn around and die anyway.
Hazards
Blizzards are the Alpine biome’s defining threat. They roll in without warning, dropping visibility and massively accelerating stamina drain for their entire duration. A team caught in a blizzard without cold protection can burn through their stamina bar in seconds, leading to grip failures on the icy walls and a cascading fall. There is no shelter mechanic in PEAK — you cannot wait out a blizzard in a safe spot. You continue climbing through it or you deplete and fall.
Icy walls require more precise grip timing than the rock faces of the lower biomes. The grip window on ice is narrower, so the free-form wall-climbing rhythm that works in the Tropics will fail more often in Alpine. Players need to be more deliberate with their timing and avoid extended stretches on open ice faces during blizzards.
Essential Gear
Hand warmers are non-negotiable. Every member of the team needs at least one before entering Alpine. Hand warmers provide cold resistance that counteracts the stamina drain from cold air and blizzards. They can be purchased at shops before the Alpine transition or found as drops in the Tropics and lower Alpine. If your team reaches the Alpine entrance without hand warmers, either backtrack to find or buy some, or accept that this run has a very high chance of ending here.
Magic Beans are one of the most valuable items in the Alpine biome. Planted on a surface, they grow a beanstalk that creates a vertical climbing shortcut — and in Alpine, where icy vertical sections are the most dangerous part of the traverse, a beanstalk can bypass an entire ice face entirely. Stock Magic Beans before Alpine if you can find them.
Survival Tips
- Use hand warmers proactively — activate them when you see blizzard conditions starting, not after your stamina is already half gone.
- Plant Magic Beans at the base of tall ice walls to create safe shortcuts through the most dangerous vertical sections.
- Slow down your climbing rhythm on icy walls. The extra second per move is worth it compared to a missed grip costing you a fall.
- Eat before blizzards arrive, not during. Mid-blizzard inventory management with dropping stamina is the worst time to be rummaging around.
- In co-op, the player with the most hand warmers should position at the front of the climb to anchor the group if blizzard conditions worsen.
Food Sources
Alpine has limited native food sources. Stock up before entry — carry whatever cooked food and shroomberries you collected in the Shore and Tropics. Some supply crates appear in lower Alpine, but you cannot rely on finding them. Arriving with a full stamina bar and a food surplus is the single biggest predictor of successfully clearing Alpine. For a deeper breakdown of the items worth carrying through this section, check our PEAK items guide.
Mesa: Sun, Shadow, and the Canyon Crossing
The Mesa is PEAK’s most recently added biome and its most strategically demanding. Where Alpine punishes you for lacking the right gear, Mesa punishes you for moving without thinking. The entire biome is built around a single rule that applies to every step you take: stay in the shadow or lose your stamina to the sun.
Hazards
The Mesa’s blistering sun is a passive stamina drain that activates whenever players stand in direct sunlight. Exposed rock faces, wide plateau sections, and open canyon rims all count as sunlit terrain. Step out of shadow for more than a few seconds and your stamina bar starts falling at a rate that compounds fast. There is no cold here, no rain, no exploding bushes — just the relentless overhead sun and the shade of canyon walls and rock overhangs.
This creates intense route planning pressure unlike anything in the lower biomes. Every traverse must be plotted for shadow coverage. The path along canyon walls and under rock overhangs is almost always longer than the direct route, but the direct route will empty your stamina bar. Learning to read the Mesa’s geometry — identifying which overhangs provide usable shade corridors — is what separates efficient Mesa teams from depleted ones.
The canyon crossing is the Mesa’s peak danger moment. The massive canyon splitting the biome must be crossed, and the crossing route exposes players to sunlit sections they cannot fully avoid. This is where runs die in the Mesa — teams who have been careful throughout the biome arrive at the canyon transition with half stamina and nothing left in the food bar. Pre-plan the canyon crossing route, eat before you start it, and move fast.
Essential Gear
There is no specialized gear that directly counters the Mesa’s sun mechanic. The entire solution is positioning and route planning. Rope cannons are exceptionally useful here for connecting shade spots across gaps that would otherwise require sunlit traversal. Use them to zip between overhangs where direct climbing would leave you exposed.
Survival Tips
- Plan your entire route before moving, not while you’re moving. Identify the shade corridor from start to finish, then execute it.
- Hug canyon walls and rock overhangs at all times. The longer shadow path is always better than the short sunlit route.
- Eat immediately before the canyon crossing and enter it with as close to a full stamina bar as possible.
- Use rope cannons to leap between shade points across open gaps rather than traversing the sunlit terrain between them.
- Co-op tip: the player who is best at route reading should navigate during the Mesa, calling out shade corridors and canyon line for the group.
For a detailed breakdown of the Mesa’s specific canyon route and all known shade corridors, see our PEAK Mesa biome guide.
Food Sources
The Mesa is arid. Native food sources are sparse and unreliable. Eat anything you collected from the Alpine or early Mesa supply caches before the canyon crossing, and do not save food for after it — the sun drain on the canyon approach and crossing itself is where you need the calories. The Caldera after the Mesa has no food sources either, so arrive at the Mesa’s end with exactly zero food reserves: consume everything before the climb into Caldera territory begins.
Caldera: Island-Hop or Die in the Lava
The Caldera replaces the Mesa’s strategic pressure with something more visceral: molten rock rising beneath you and fire explosions detonating across the landscape. Speed and commitment are the Caldera’s requirements. Teams that plan carefully in the Mesa survive. Teams that move carefully in the Caldera die. The lava rises, and it doesn’t care about your plan.
Hazards
Rising lava is the Caldera’s primary mechanic. The magma level periodically rises across sections of the biome, eliminating any “camping” option on lower island surfaces. You cannot pause, regroup, or eat food on a low-lying rock and wait for the moment to pass. The lava will reach you. Teams must keep moving forward and upward, island-hopping to higher ground as lower islands become submerged.
Fire AoE explosions are the biome’s secondary hazard. These large area-of-effect detonations are telegraphed — they produce a visible warning before they fire. Watch for the indicator and move out of the zone before detonation. A fire explosion that lands on a team member can knock them off an island into the lava gap, which is usually fatal. Unlike the exploding bushes of the Tropics, the Caldera’s fire AoEs are avoidable if you’re watching. The problem is that teams focused on the rising lava behind them stop watching the AoE indicators ahead.
Essential Gear
No specialist gear counters the Caldera’s hazards directly. What matters here is speed and stamina. Arrive with a stamina bar topped off from whatever Mesa food you still had and burn it on fast movement. Rope cannons are useful for reaching islands that are slightly too far for a direct jump. Pitons matter less here — the islands are small and lava below means falling off an island is generally fatal regardless of your anchor position.
Survival Tips
- Pre-plan the island-hop route before the lava starts rising. Identify the next two islands ahead at all times.
- Move fast. The Caldera is not a biome for cautious, deliberate movement. Commit to each jump and island landing.
- Watch the AoE indicators actively. Assign one team member to call out fire explosion zones so the whole team can clear them.
- Do not linger on any island. Even islands that feel high enough will be threatened if you pause too long while lava rises.
- In co-op, roped players need to coordinate jumps. A poorly-timed jump that pulls a roped teammate off an island into the lava gap can end two runs at once.
Food Sources
There are no food sources in the Caldera. This biome is pure movement. Whatever stamina you arrive with is what you have for the entire traverse. Eat everything before entering and rely on efficient movement to conserve what’s left.
Kiln: The Final Push to the Summit
The Kiln is PEAK’s final biome and the volcanic interior of the mountain itself. Claustrophobic, dark, and relentless, the Kiln offers no new hazard mechanics — it simply demands that you arrive with enough stamina to finish the climb through its labyrinthine passages to the summit bridge at the top. Teams that reach the Kiln with stamina to spare will clear it. Teams that arrive depleted will fail within sight of the end.
Hazards
The Kiln’s primary hazard is stamina depletion on the final push. The interior is dark and the climbing sections are tight and vertical. There are no environmental hazards comparable to Alpine’s blizzards or the Caldera’s lava rise — the Kiln is the gauntlet of accumulated exhaustion from everything that came before it. Every stamina inefficiency in the previous five biomes compounds here.
The darkness adds disorientation to the challenge. Navigation through the Kiln’s passages requires attention to the route. Teams can lose time to wrong turns or dead ends in the lower Kiln sections, burning stamina they cannot afford to lose.
Essential Gear
Arrive in the Kiln with the fullest stamina bar your team can manage. There are no food sources, no caches, nothing to recover with. The Kiln is purely a test of what you conserved from earlier biomes. If your team has hand warmers left over from the Alpine, keep them — the Kiln’s volcanic passages have heat fluctuations that can occasionally drain stamina similarly to cold air in the Alpine.
Survival Tips
- Consume any remaining food immediately before entering the Kiln. There is nothing inside.
- Move deliberately through the lower passages to avoid wrong turns. Speed matters less than accuracy in the dark sections.
- The climb to the summit bridge is the last stretch — empty your remaining stamina bar on it. Hold nothing in reserve.
- In co-op, keep the team together through the Kiln. Getting separated in the dark with no food and low stamina is how teams fall apart at the last moment.
- The exit bridge at the summit is visible from the upper Kiln. Once you see it, you’re almost there.
Food Sources
None. Eat everything before you enter.
Frequently Asked Questions
How many biomes are in PEAK?
PEAK currently has six biomes that all runs pass through in a fixed order: Shore, Tropics, Alpine, Mesa, Caldera, and Kiln. The Mesa is the newest addition, added in a recent update. Each biome has unique hazards and environmental mechanics that require different survival approaches.
What is the hardest biome in PEAK?
Alpine is the most punishing biome for unprepared players because blizzards drain stamina rapidly and cannot be waited out. The Mesa is the most strategically demanding because the shade-or-die sun mechanic requires constant route planning. Most runs that fail before the summit end in either Alpine (missing hand warmers) or the Mesa canyon crossing (arriving with insufficient stamina).
Do you need hand warmers for every PEAK run?
Yes, effectively. Hand warmers are non-negotiable for the Alpine biome — without cold protection, blizzards will drain your stamina bar too quickly to maintain grip on the icy walls. Every team member needs at least one hand warmer before entering Alpine. They can be purchased at shops or found as drops in the Tropics and lower Alpine.
Can you go back to a previous biome in PEAK?
No. PEAK is a linear upward climb. Once you ascend through a biome transition, you cannot return. This makes resource management critical — everything you collect in the Shore and Tropics is all you will have for the harder biomes above. Over-preparing in the lower biomes is always better than under-preparing for the upper ones.
What food should I stock before the Alpine biome?
Carry as many cooked coconuts from the Shore as possible, supplemented by safe-color shroomberries from the Tropics. The goal is to arrive at Alpine with a full stamina bar and enough food to recover from at least one blizzard event. Our PEAK beginners guide covers the full resource priority list for your first climb.
