From ziplining at The EDGE to hiking fourteeners, here are the must-do outdoor adventures in Colorado this year, all within reach of the Denver metro.
Colorado is one of the premier adventure destinations in the United States, and 2026 is shaping up to be an incredible year for outdoor enthusiasts. Whether you are a lifelong Coloradan or visiting for the first time, this bucket list covers the essential experiences that make our state legendary for adventure seekers. Best of all, most of these are within a short drive of the Denver metro area.
Ziplining at The EDGE in Castle Rock should be at the top of your list if you have not experienced it yet. Our 10-line zipline tour takes you soaring above the Colorado landscape with views of Pikes Peak and the Front Range that you simply cannot get any other way. The progressive line design means you build confidence and speed throughout the tour, finishing with the longest and fastest lines when your adrenaline is pumping its hardest. It is consistently rated as one of the top outdoor activities in the Denver area.
Hiking a fourteener is the quintessential Colorado bucket list item, and 2026 is the year to check it off. Colorado has 58 peaks above 14,000 feet, and several are accessible to fit hikers without technical climbing experience. Mount Bierstadt and Quandary Peak are considered excellent first fourteeners with well-maintained trails and moderate distances. Start training with local hikes around Castle Rock and the surrounding Douglas County trail system to build your elevation fitness gradually.

Whitewater rafting on Clear Creek or the Arkansas River offers a completely different kind of adrenaline rush. From gentle Class II floats suitable for families to intense Class IV rapids that will test experienced paddlers, Colorado's rivers provide world-class rafting from May through August. The Arkansas River near Buena Vista is particularly popular, with multiple outfitters offering half-day and full-day trips through scenic canyons.
Rock climbing at one of Colorado's legendary outdoor crags is a must for anyone with even a passing interest in the sport. Eldorado Canyon near Boulder, Shelf Road near Canon City, and Clear Creek Canyon between Denver and Idaho Springs all offer world-class climbing on real rock. If you are new to the sport, The EDGE Adventure Tower's 50-foot climbing wall is a perfect place to learn the basics before heading outdoors.
Mountain biking deserves a spot on every Colorado adventure list. The state has thousands of miles of purpose-built singletrack, and the Front Range alone could keep you busy for years. Closer to Castle Rock, the Ridgeline Open Space and Spruce Mountain trails offer excellent intermediate riding with stunning views. For more advanced terrain, head to Buffalo Creek or the trails around Deckers for technical singletrack through pine forests.
Finally, try something that scares you a little. Whether that is your first aerial ropes course at Sky Trek, a tandem paragliding flight above the mountains, a via ferrata route on a canyon wall, or simply standing at the top of The EDGE Adventure Tower before taking the free-fall plunge, growth happens at the edge of your comfort zone. Colorado provides endless opportunities to test your limits in environments so beautiful that the fear melts into exhilaration almost immediately.
