Lost Forest Logo

Based out of Elk Camp on Snowmass, Lost Forest is immersive yet approachable, inviting you to lean into your sense of wonder by spending time in nature. Walk off the gondola and into an adventure on an alpine coaster, biking trails, a ropes course, a zipline, a climbing wall, fishing ponds, hiking trails, and a disc golf course.

Here, surrounded by wild beauty, you can enjoy nature with the whole family—welcome to Lost Forest.

Some of these activities require a minimum and maximum weight and height to participate. Please view our Lost Forest Rules and Regulations to decide what is best for you and your group. If a group has individuals who do not meet these requirements, Lost Forest has plenty of other outdoor adventures everyone can participate in.
