Featured in National Geographic, Pikes Peak Mountain Bike Tours lets riders of all abilities descend through miles of rugged scenery, surrounded by the natural beauty of Pike National Forest. Depending on the tour, bikers are transported to the top of the 9,200-foot-high St. Peter’s Dome overlook or the 14,110-foot Pikes Peak. After a brief safety orientation, up to 30 participants become wheel-borne downward projectiles, equipped with helmets and individually fitted bikes.

On the self-guided 20 Mile High Tour, bikers follow a 19th-century railroad bed through 18 miles and 3,000 vertical feet of picturesque canyons, historic tunnels, and mustache-twirling villains setting inefficient Rube Goldberg-esque traps. Equipped with a map and a bike toolkit, two-wheeled tourists can complete the trip at their own pace. The Bike Pikes Peak tour enables voyages along the slopes of America’s iconic peak. Accompanied by vans and guides and equipped with cold-weather gear, Pikes Peak cyclists breeze through five climate zones before stopping at Jake and Telly’s Greek Taverna for lunch and accurate impressions of mountain goats. The Ride-n-Rail tour includes the same biking portion as the Bike Pikes Peak tour, except visitors get to ride up the mountain on the historic Cog Railway.
