The Rocky Mountain National Park area is perfect for biking. Within the park make sure you stay on established roads and keep watch for cars, as well as those challenging 7% gradient climbs. Tons of single track and road rides can be found outside of the park as well.
Biking is a wonderful pastime no matter where you go, but when you enjoy it amidst beautiful natural scenery it truly is something special.
The Horseshoe Park/Estes Park Loop is a particularly popular trail that runs for 16 miles. To get there travel west from Estes Park on U.S. 34 past Aspenglen Campground and Rocky Mountain's Fall River entrance. Turn toward the east at the Deer Ridge Junction, traveling on U.S. 36 through the Beaver Meadows park entrance. The trip may take 1 to 3 hours.
Bicycles are also allowed on Bear Lake and Trail Ridge roads. Bear Lake Road rises 1,500 feet over 8 miles from Moraine Park to Bear Lake. (Moraine Park is a gorgeous valley surrounded by mountains). Bear Lake is the starting point for several trails leading into the backcountry. Stop at Sprague Lake and Glacier Gorge Trailhead as you ride to take advantage of parking, hiking, and photo opportunities. The whole trip takes approximately 2 to 4 hours.
