    Route Description for Peak to Peak Highway

    The Peak to Peak Highway is a classic Boulder road bike ride. The Peak to Peak Hwy is a 96.6 km strip of road that connects Blackhawk, CO, and the I-70 corridor to Estes Park and Rocky Mountain National Park. The full ride is a 96.6 km one-way trip that is listed as one of Colorado’s most epic bike rides, with a total elevation gain of 1,547 m! This slightly shorter out & back version is a ride that can be done solo in a day without the need for a support vehicle.

    Begin the ride in the town Nederland, CO, and cycle north out of town via the Peak to Peak Highway. After a mile of steady climbing at 8% grade, the road will drop down into a valley around Caribou Ranch. The second and longer climb with a sustained grade of 8% will follow the brief downhill. Climb all the way to the small mountain town of Ward (elevation 2,820 m).

    After Ward, you will begin a long downhill section all the way down to Peaceful Valley with amazing views of Indian Peaks and Sawtooth Mountain! Peak to Peak Hwy will arrive at a junction with S St. Vrain Dr.; this is the turnaround point.

    Cycle back the way you came along the Peak to Peak Highway, climbing out of Peaceful Valley and back up to Ward and back to the starting point in Nederland.
