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 GuideDesbloqueie a Telecadeira pela rota Verde, depois suba em uma cadeira e sente-se. A medalha é concedida pela cadeira, e não por o lift estar aberto.
Não. A Telecadeira estar disponível só dá a você algo onde sentar; a conquista em si pertence às cadeiras.
Sim. O gatilho é a pose de viagem em uma cadeira, então ficar em uma estação ou ao lado de uma cadeira não basta.
Não. Nada no gatilho depende de chegar à estação do outro lado.
Não. Qualquer ponta da Telecadeira serve como ponto de embarque.
Não. A mesma lógica de pose existe em mais de uma cadeira, então você não precisa encontrar uma em particular.
Nenhum número de segundos específico é exigido. Mantenha a pose de viagem por tempo suficiente para ser registrada antes de descer.
Confirme que você estava sentado em uma cadeira e não em pé na estrutura, depois tente outra cadeira e deixe a pose se acomodar antes de descer.
Não. “Grande Subida” vem de chegar ao ponto mais alto, que é um gatilho separado. Guia de Big Climb
