Bike Gold Camp Off-Road is an exceptional experience and a true off-road adventure.  AOW operates under permit of the Pike National Forest and is an equal opportunity employer and provider.

A self guided adventure in the heart of the Colorado Rockies is a must do experience.  The historic route follows an old Rail Road Grade and is an exceptional route with old tunnels and a gentle grade with lots of adventure.

WARNING- Pikes Peak by Bike is considered a high Adventure level tour.  Temperatures will be 30-40 degrees cooler than Colorado Springs and the air is thin.  Most mornings the summit temperature is near freezing.  Dress in layers.  Long pants or sweats or appropriate.  You can put extra cloths in the chase van as you warm up. If this is your first time riding a bike then maybe this adventure is not for you.

Tour Description


  • Van or Jeep tour up the world famous Old Stage Road to St Peters Dome View point. (1 hour)
  • 17-mile (Down hill) bike ride from the 9690′  Old Colorado City on a historic railway bed.
  • Suitable for most ages and abilities, some intermediate sections, loose gravel and awesome tunnels.

Adventure Overview:
Take a ride through history…

This ride is best suited for anyone who wants a moderate ride but also wants to get off the beaten path.  The route has some intermediate to advanced sections depending on rider ability. Great for corporate adventures!

The tour offers great vistas of Colorado Springs, Cheyenne Canyon, and the Eastern plains of Colorado. The 17-mile ride starts at St. Peter’s Dome overlook and follows the Historic Gold Camp Road, an old railroad bed used for transporting gold at the turn of the century. We will descend on bike through beautiful aspen and pine forests, old railroad tunnels, and rock formations that will take your breath away.

The road is gravel, which at times can be loose. Experienced mountain bikers consider this ride easy with intermediate sections. Those who are new to mountain biking will find the ride a worthy challenge but not too crazy. To do this entire ride plan on it taking four hours. It is easy to shorten the ride depending upon the needs of the group.

If you’re a trailblazer at heart, then sign up for the self guided option. Your group will be on your own once the driver drops you at the trail head.  Some experience with bikes is a good idea as you may have to put your chain back on or perform minor first aid.
