The Lost Forest at Aspen Snowmass is a must-experience for adventurous visitors and locals alike. Soar on ziplines through the trees, hike miles of beautiful trails, or test your skills on the Treeline Trial Challenge Course, a fun ropes course with varying levels of difficulty that’s sure to test even the most adept. Dubbed “Colorado’s Adventure Park,” this area is something you won’t want to miss.

The Lost Forest is tucked into the woods near Elk Camp on Snowmass, and fits within the feel of the area. Features are seamlessly integrated into the forest, and are built with sustainability in mind. The idea was to have as little of an environmental impact as possible, and to reduce the size of the course’s footprint. Zipline platforms are situated in such a way to allow trees to continue growing, and natural features were used as much as possible while building the various courses.

Situated as high as 40 feet above the ground, the Treeline Trial Challenge Course offers five paths of varying difficulty, rated similarly to a ski slope. Green circles are the easiest paths, with the double black-diamond course rated as the most challenging. Obstacles range from walking on wires to balancing on logs and everything in between. As route difficulty increases, more upper body strength is required and obstacles become more difficult.

Have a free afternoon? Opt for the Canopy Run Zipline Tour, an exciting three-hour mountain adventure that incorporates seven ziplines, aerial rope bridges and the nation’s only diagonal rappel.

If heights aren’t your thing, check out the Breathtaker Alpine Coaster, a thrilling 7- to 9-minute ride down the mountain on an elevated track. Guests can reach speeds of up to 28mph, and are rewarded with amazing views from an elevation of 9,000 feet.

Looking for something a little more low-key? The Lost Forest also offers numerous hiking trails, a climbing wall with 14 auto-belays, a fishing pond and a disc golf course- to name a few. There truly is something for everyone.

“We were trying to build an authentic and unforgettable experience for guests that doesn’t feel like you’re in Disneyland,” said David Gray, Snowmass’ Director of Guest Services, “I feel like we’ve achieved that.”

With extended hours this summer, the Lost Forest is open 9am–4pm every day, except Tuesdays due to the weekly Farm-to-Table Dinner that runs from 4:30pm–9pm. Farm to Table Tuesdays occur every week starting early July through mid-August and features local farms, breweries and distilleries. On these Tuesdays you can take in all of the mountain adventure, with sunset laps on the Breathtaker Alpine Coaster, extended hours at the Snowmass Bike Park and breathtaking views of Colorado’s high alpine at dusk.
