Grand Mountain Adventure: Wonderlands

Grand Mountain Adventure: Wonderlands is a casual skiing game letting you explore a number of ski resorts and mountains in any order. There are 12 ski open-world resorts in total, with unlockable ski lifts giving you useful shortcuts between areas once discovered.

Across each ski resort are a number of challenges representing different skiing disciplines. Some challenges are hidden, including secrets trails off the beaten path. For collectable hunters, there are Ski passes to find.

None of these challenges are required for exploration however, and it's possible just to ski freely as you visit new areas. It's even possible to disable all challenges, collectables, and NPCs entirely via ZEN mode for a relaxing ski trip.
