Cairn Beginner Guide

Cairn is resource management on a vertical wall. Every move costs stamina, every piton is a checkpoint you paid for, and every route decision has to be made before you commit to a pitch — because you cannot descend the same path you climbed. New players usually lose runs not to a single impossible move but to a slow accumulation of small overdrafts: climbing one section too long without resting, skipping a piton to save time, or pushing into weather that quietly removes half your grip.

This beginner guide walks through the five systems that decide your first successful ascents: climbing fundamentals, gear progression, weather and time management, route planning, and stamina economy. Read them in order — each one assumes the previous habit is already automatic.

The First Climbs

Walkthrough

1Climbing Fundamentals

Treat the wall as a budget, not a challenge. Every move costs stamina, so the first habit to build is resting on ledges whenever your stamina drops below 30%. That threshold is not arbitrary — it is the point where you still have enough left to reach a rest position if the next hold turns out to be worse than it looked.

Plan your route upward before committing to a pitch. Cairn does not let you reverse a climb along the same path, so a line that runs out of holds twenty metres up is not a detour, it is a dead end. Read the colour coding as you go: yellow chalk marks safe holds, red marks unstable ones. Getting fluent at spotting those two colours at a glance is the single fastest early improvement most players make.

2Gear Progression

You begin with basic pitons and a 30m rope. That kit is enough for the opening sections but nothing beyond them, so the upgrade order matters. Upgrade the harness first, because it improves stamina efficiency and therefore compounds with every single move you make afterwards. Shoes come second for better grip on wet rock — a direct counter to the game's most common environmental hazard.

The ice axe unlocks at Cairn 2 and is essential for frozen sections; do not attempt those routes without it. The drone camera unlocks at Cairn 3 and changes route planning entirely, because it lets you scout ahead without committing your body to the wall first.

3Weather And Time Management

Start each climb at dawn. You get 12 hours of daylight, and that window is the real difficulty setting of any long ascent — a route that is comfortable with nine hours left becomes a gamble with three.

Rain reduces grip by 40% and makes every hold riskier, while fog obscures route markers and removes your ability to plan more than a few metres ahead. If a storm approaches, find a bivouac ledge and wait it out. Pushing through bad weather is the number one cause of fatal falls in Cairn, and the time you "save" is almost always less than the time a fall costs you.

4Route Planning

Before climbing, study the mountain face with binoculars. You are looking for three things: rest ledges, which appear roughly every 15 to 20 metres; bail-out routes for emergencies; and the overall angle of the line you intend to take.

On Cairn 1 the choice is explicit. The left face is easier but slower; the right face is steeper but faster. Neither is correct in the abstract — pick based on your current skill level and, critically, on how much daylight remains. A steep fast line at hour two is a reasonable risk; the same line at hour nine is not.

5Stamina Economy

Every action has a stamina price, and knowing the numbers turns vague caution into actual planning. Climbing drains 3 per second, placing a piton costs a flat 8, hanging drains 2 per second, and resting on a ledge restores 5 per second. Because hanging still costs stamina, indecision on the wall is itself an expense.

Always climb with at least a 40% stamina buffer for emergencies. Eat energy bars when stamina drops below 50% — they restore 30% instantly but take 5 seconds to consume, so you need to be in a stable position before you start eating, not halfway through a reach.

Action	Stamina Effect	Practical Note
Climbing	−3 per second	Your baseline burn. Long unbroken sections are the main drain on any pitch.
Hanging	−2 per second	Pausing to decide is not free. Read the wall before you leave the ledge.
Piton placement	−8 flat	Cheap insurance compared with losing a section of progress to a fall.
Resting on a ledge	+5 per second	The only sustainable recovery. Plan ledges into the route in advance.
Energy bar	+30% instantly	Takes 5 seconds to consume — use from a secure position only.

Gear	Availability	Why It Matters
Basic pitons + 30m rope	Starting kit	Your first checkpoints. Everything early revolves around spending them well.
Harness upgrade	First upgrade priority	Improves stamina efficiency, which compounds across every move of every climb.
Shoes upgrade	Second upgrade priority	Better grip on wet rock — a direct counter to rain's 40% grip penalty.
Ice axe	Cairn 2	Essential for frozen sections. Do not attempt those routes without it.
Drone camera	Cairn 3	Scout routes ahead and mark holds from a distance before committing.

FAQ

Common questions

What happens when I fall?

You respawn at your last placed piton and keep every item and resource in your inventory — the only thing you lose is progress back to that checkpoint. Falling without a recent piton is the most punishing outcome and can cost 20 to 30 minutes of climbing. This is exactly why the five-metre placement rule on hard sections is worth the 8 stamina each time.

How do I get more pitons?

You start with 2 to 3 pitons from the training facility, and completing all 8 training walls earns a bonus piton from the reward box. Beyond that, explore side paths for extras, and always keep failed piton scraps — two scraps combine into one new piton at any bivouac. Later in the game you can find indestructible pitons that never break, which are essential on the longest climbs.

Should I ever skip a bivouac to save daylight?

No. Bivouacs are survival hubs, not save points. At each one you can cook recipes from collected ingredients, repair broken equipment, craft pitons from scraps, refill water bottles, and check the barometer — which runs about 15 seconds ahead of actual weather changes. Skipping one because you feel confident almost always means arriving at the next climb under-resourced and exhausted.

How should I plan a route before climbing?

Study the face with binoculars first and mark rest ledges — they appear roughly every 15 to 20 metres — plus at least one bail-out route. In game, press L1 to enter route review mode for a zoomed-out view of the whole wall including ledges and cracks, and press Triangle to move the camera freely. Look for routes with a ledge halfway up so you can stop, recover used pitons, and reuse them on the second half.

What are the most common beginner mistakes?

Taking shortcuts that burn resources faster than a slower route with natural rest spots; ignoring surface cracks, since more cracks mean easier climbing and smooth rock is harder to grip; placing pitons after a fall instead of before a hard section; skipping bivouacs; and rushing a climb instead of reading the rock face. Slow, deliberate movement prevents committing to bad holds.
