Rocky Mountain National Park and Estes Park Bike Tours


New Venture Cycling downhill guided bicycle tours are a fantastic way to see, hear, smell, learn and experience Rocky Mountain National Park and the Estes Park area.  Our guides will share what is beautiful and exciting, from flora and fauna to the peaks that surround you as you cruise down the road, soaking it all in!  

Our tours are MOSTLY downhill in nature, but we are in the mountains, so pedaling a little uphill or on a flat road may be encountered. Throughout the tour, the guides will inform riders about the upcoming terrain and best gearing for the situation.  If at any point pedaling becomes too difficult, hopping into the support van for a portion of the tour is an option.

For some tours, we offer a couple of van spots for group members who prefer not to ride a bike. Van spots are only available if other group members will be riding. You can check availability of those spots when reserving your tour.


EASY - Mostly downhill, some flat sections, shorter length.

EASY TO MODERATE - Mostly downhill, some flat sections, some short uphills.

MODERATE - Mostly downhill, some flat sections, more uphill or rolling.

MODERATE TO HARD - Downhill, flat, and long uphill sections, but gentle grades.

HARD - Lungbusting uphill all the way without stopping.  There is nothing on our agenda that will be this rating.

These guidelines are general and should be applied to an average rider. For example, for a person who hasn't ridden a bicycle for 30 years, an "Easy" ride may become "Moderate." 

Another factor to apply is that most tours occur on paved roadways that we share with car traffic. What we find is that most drivers are respectful and cautious in Rocky Mountain National Park and the Estes Park Valley, and sharing the road goes well. Our tours in Rocky happen in the morning, when traffic is light, but we do have some cars passing as we ride and for some people this may increase the difficulty rating of the tour.


Before we begin riding on our tours, the guides will go over our rules of the road, safety considerations and ensure that each rider has become familiar with the bicycle's gearing and braking systems.

Colorado has some of the most specific laws regarding where a bicyclist should ride, and just as importantly, where a bicyclist should not be obligated to ride, in the nation. The general rule is that:

If the right-hand lane then available for traffic is wide enough to be safely shared with overtaking vehicles, a bicyclist shall ride far enough to the right as judged safe by the bicyclist to facilitate the movement of such overtaking vehicles unless other conditions make it unsafe to do so. A bicyclist may use a lane other than the right-hand lane when:

  • Preparing for a left turn at an intersection or into a private roadway or driveway;
  • Overtaking a slower vehicle; or
  • Taking reasonably necessary precautions to avoid hazards or road conditions.

A bicyclist shall not be expected or required to:

  • Ride over or through hazards at the edge of a roadway, including but not limited to fixed or moving objects, parked or moving vehicles, bicycles, pedestrians, animals, surface hazards, or narrow lanes; or
  • Ride without a reasonable safety margin on the right-hand side of the roadway.
