The Lost Forest isn’t hard to find — it’s just hard to see. Tucked in among the trees and rocks at Elk Camp on Snowmass Mountain are an alpine coaster and zip lines, biking trails, ropes challenges and climbing walls.

There are ponds to fish in, creeks to hike along, places to enjoy nature alone or in groups, two disc golf courses and passionate guides to help you find your next adventure. Here, surrounded by wild beauty, you’ll find your next wild adventure. Welcome to Lost Forest.

Please review our Lost Forest Rules & Regulations before purchasing your Lost Forest admission.
