Activities
Breathtaker Alpine Coaster: The signature attraction. A mountain coaster that winds through the forest, rider-controlled for speed. Popular with kids and adults alike. Height and age restrictions apply.
Canopy Tour: Multiple zip lines connecting platforms in the trees. Guided tours with safety briefings. Views of the surrounding mountains between lines.
Treeline Trial: A challenging rope course through the aspen canopy. Different difficulty levels let participants choose their adventure. Good for teens and adults seeking challenge.
Rugged Ascent: Climbing wall and bungee trampoline area. Good for younger kids or those not ready for the higher elements.
Lunch Loops: Smaller rope elements and climbing structures for the youngest visitors. Designed for kids who aren't quite ready for the bigger courses.

Tips
Arrive early. The most popular activities develop lines, especially for the alpine coaster. Morning slots are often easier.
Wear closed-toe shoes. Required for most activities. Sandals and flip-flops won't work.
Plan for weather. Activities close during lightning. Afternoon thunderstorms are common—morning visits are safer bets.
Combine with lunch. Elk Camp is right there. Make a half-day of activities and dining.
Frequently Asked Questions
Is it open in winter?
No. Lost Forest operates only in summer, typically mid-June through Labor Day. Winter brings ski operations.
Can parents watch without participating?
Yes. The gondola ride up is included with activity tickets or can be purchased separately. Non-participating adults can enjoy Elk Camp dining and views.
Is it scary?
Depends on the activity and the person. The alpine coaster is thrilling but not terrifying. Higher elements like zip lines require comfort with heights. Start with lower-intensity options if uncertain.
What if it rains?
Light rain may not close activities. Lightning absolutely will. Check conditions and consider morning visits to avoid afternoon storm closures.
