The highest point in Big Walk sits at the center of the island, on the mountain framed by the five colored towers. Climbing it by hand is possible but slow and easy to fail. The chairlift near the Green Tower carries you almost all the way there, leaving only a short walk up a narrow path to the summit.
Quick answer: Complete the Green Tower to power the chairlifts, ride the western chairlift from the Green Tower station until you pass directly under the mountain, then follow the path on the left up to the orange triangular structure at the top. Touching that structure unlocks Big Climb.
What you need before the climb
Two things must be in place before the route works. The map makes the summit easy to spot, and the chairlift gives you the practical way up.
| Requirement | How you get it | Why it matters |
|---|---|---|
| Island map | Complete the Red Tower | Adds the triangular marker for the highest point between the towers |
| Working chairlift | Complete the Green Tower | Powers the lifts so you can ride toward the mountain instead of climbing on foot |
Without the Green Tower done, the chairs will not move and you have no easy approach. The map is not strictly required, but the marker between the five towers makes it far simpler to judge where to get off.

Climbing the mountain path to the summit

How Big Climb unlocks
There is no puzzle or item to collect at the summit. Reaching the orange triangular structure at the highest point is the whole trigger. The Big Climb trophy pops the moment you arrive there.
If the achievement does not appear, the reason is almost always position. Simply riding the chairlift or standing at the overlook does not count. You have to leave the chair and physically reach the orange structure at the top for the game to register it.
| Situation | Result |
|---|---|
| Staying on the chairlift the whole way | Does not trigger Big Climb |
| Stopping at the overlook with the radio and flare box | Does not trigger Big Climb |
| Reaching the orange triangular structure at the summit | Unlocks Big Climb immediately |
Once you touch the structure at the top, the highest point is done. The chairlift handles the distance, and the summit itself is only about steady footing on the last narrow stretch, so the trophy is one of the quicker ones to add once the Green Tower is complete.
