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.
Big Walk Big Sit Achievement: How to Unlock It
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
Quick Answer
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
Where Are You Stuck?
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 GuideHow to Unlock Big Sit
Three 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.
What Actually Triggers Big Sit?
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.

Unlocking the Chairlift vs Sitting in It
Two different states. Only the second one awards Big Sit.
- 1Green Route
- 2Chairlift Unlocked
- 3Chairlift Running
- 4Sit in a Car
- 5Big Sit Trigger
Sitting in a car
Boarding a car puts your player into the riding pose the car is checking for. This is the state that awards the Chairlift medal.
Big Sit Not Unlocking?
Work down the list. The first line that is still true is the one to fix.
1. Did you actually sit in the chair?
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 Step2. Was the Chairlift active?
If the lift is not usable yet, this is a Chairlift problem rather than an achievement problem.
Open Chairlift Guide3. Try another car
The 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.
4. Stay seated for a moment
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.
5. Platform achievement delayed?
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.
What Is Not Proven to Be Required
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.
Big Sit vs Big Climb
Both involve the Chairlift, but they are two different achievements with two different triggers.
Big Sit
Awarded from a ChairLift car while you are seated on it.
Big Climb
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 GuideBig Sit FAQ
Come si sblocca “Grande seduta” in Big Walk?
Sblocca la seggiovia tramite il percorso verde, poi sali su una seggiola e siediti. La medaglia è assegnata dalla seggiola, non dal fatto che l’impianto sia aperto.
Sbloccare la seggiovia sblocca “Grande seduta”?
No. Il fatto che la seggiovia sia disponibile ti dà solo qualcosa su cui sederti: l’obiettivo in sé appartiene alle seggiole.
Devo sedermi sulla seggiovia?
Sì. L’attivatore è la posa da passeggero su una seggiola, quindi stare a una stazione o accanto a una seggiola non basta.
Devo arrivare fino all’altra estremità?
No. Niente nell’attivatore dipende dall’arrivo alla stazione opposta.
Grande seduta richiede una stazione specifica della seggiovia?
No. Entrambe le estremità della seggiovia possono fungere da punto d’imbarco.
Serve una seggiola specifica?
No. La stessa logica della posa è presente su più seggiole, quindi non devi trovarne una in particolare.
Per quanto tempo devo restare seduto?
Non è richiesto un numero preciso di secondi. Mantieni la posa da passeggero abbastanza a lungo perché si registri, prima di scendere.
Perché “Grande seduta” non si è sbloccato dopo che sono salito sulla seggiovia?
Assicurati di essere stato seduto su una seggiola e non in piedi sulla struttura, poi prova un’altra seggiola e lascia che la posa si assesti prima di scendere.
Salire sulla seggiovia sblocca anche “Grande arrampicata”?
No. “Grande arrampicata” si ottiene raggiungendo il punto più alto, che è un attivatore separato. Guida a Big Climb
Devo prima completare la Torre Verde?
Nella progressione normale la seggiovia va prima sbloccata, e quel percorso passa per l’area verde. Walkthrough dell’area verde
