Unlocking the Chairlift
Finishing the Green route places the finished key and opens the lift. At that point the Chairlift is available, but Big Sit has not fired.
Unlock the Chairlift through the Green route, then actually sit in a ChairLift car. Big Sit is tied to the Chairlift’s riding pose, not the unlock itself.
Big Sit is tied to the ChairLift cars themselves. The trigger is entering the sitting pose on a car, not unlocking the lift or standing at a terminus.
Big Sit


Unlock the Chairlift through the Green route, then board a ChairLift car and enter its sitting pose. The achievement is attached directly to the cars, so unlocking the system or standing at a terminus does not count.
Nothing beyond sitting in a car is required.
This is one of the gameplay achievements. See the full achievements list
Pick the line that matches your run. The Chairlift system and the sitting pose fail for different reasons.
The Chairlift is still locked
That is a progression problem, not an achievement problem. Finish the Green Key route so the Chairlift becomes available.
Open Chairlift GuideThree steps. Only the last one is the achievement trigger.
1. Make the Chairlift available
If the lift is still locked, finish the Green Key route first.
Open Chairlift Unlock Guide2. Go to a terminus
The Chairlift has a Start Terminus and an End Terminus. Either end works, so use whichever one you can reach.
3. Sit in a ChairLift car
Board a car and stay in the sitting pose. The cars carry the medal logic, so the seat is the achievement trigger.
If the achievement has not appeared, ride another car before replaying the whole Green route.
Big Sit is attached to the ChairLift cars, not to the Green Key unlock.
The achievement logic lives on the cars themselves. It checks your pose while you are using the chair, so the medal is awarded from the car rather than from the lift system being open. That is why unlocking the Chairlift and sitting in it are separate states.
You do not need any of this to ride the Chairlift.
Two different states. Only the second one awards Big Sit.
Finishing the Green route places the finished key and opens the lift. At that point the Chairlift is available, but Big Sit has not fired.
Boarding a car puts your player into the riding pose the car is checking for. This is the state that awards the Chairlift medal.
Work down the list. The first line that is still true is the one to fix.
Standing beside a car, jumping on the frame or touching the cable machinery does not put you in the pose. You have to be seated in the car itself.
Show Me the Sitting StepIf the lift is not usable yet, this is a Chairlift problem rather than an achievement problem.
Open Chairlift GuideThe pose logic sits on more than one car, so it is not tied to one special chair. If a car did not register you, step off and let another one take you.
Give the riding pose time to register before you step off. No minimum sitting time is published, so a couple of seconds is a retry, not a requirement.
The in-game medal and the Steam or PS5 notification can update at different times. Check your platform achievement list before replaying the whole Green route.
These come up often, but none of them is required.
A full trip to the other end
You do not have to ride all the way. The cars check your pose, not your arrival at the far terminus.
One specific terminus
Both ends of the lift can be used to board, and neither one is named as the required starting point.
One specific chair
The same pose logic sits on more than one car, so no single numbered chair has to be the one you take.
Reaching the highest point
That belongs to Big Climb. Sitting on the lift does not depend on where the line ends.
A fixed sitting time
No specific number of seconds is required. Stay in the seat long enough for the pose to register.
Both involve the Chairlift, but they are two different achievements with two different triggers.
Awarded from a ChairLift car while you are seated on it.
Awarded from the peak itself. The Chairlift can carry you toward that area, but sitting on it does not award the summit achievement.
Open Big Climb Guide透過綠色路線解鎖纜車,然後登上一把纜車座椅並坐下。獎章是由座椅頒發的,而不是因為纜車開啟了。
不會。纜車可用只是給了你一個可以坐的東西——成就本身屬於座椅。
需要。觸發條件是座椅上的乘坐姿勢,所以只站在終點站或座椅旁邊是不夠的。
不用。觸發條件中沒有任何一項取決於是否到達遠端的終點站。
不用。纜車的任一端都可以作為上車點。
不用。同一套坐姿判定分佈在多個座椅上,所以你不必非得找到某一把。
不要求坐滿特定的秒數。下來之前,先保持乘坐姿勢足夠久,讓它被記錄。
確認你是坐在座椅裡而不是站在結構上,然後換另一把座椅試試,並在下來之前讓坐姿穩定下來。
不會。「大爬一番」來自到達最高點,那是另一個獨立的觸發條件。 Big Climb 攻略
