Northwest of Denver and Golden, the Centennial Cone Open Space Park in the Jefferson County has a 12 mile loop with 1,800 feet of ascent that is sweet for mountain biking. The main loop rolls through meadows and pine forest along mostly singletrack with some mixed doubletrack. Most of the climbs are relatively short and very rideable. The main loop is formed by the combination of the the Travois Trail (8.5 miles) with the Elk Range Trail (3.5 miles). While most mountain bikers follow the Centennial Cone loop clockwise, it is actually enjoyable in both directions.
There are three main trailheads servicing Centennial Cone Park. The most popular trailhead is the northern trailhead located off Golden Gate Canyon Road, which provides direct access to the loop. If you are coming from the west, the western trailhead is located off Centennial Cone Road. It’s more remote and less used by mountain bikers coming from the Front Range. The third trailhead is located right on US6 to the south side of the park, and is quite popular with riders coming from Denver and the south. However, it is located below the loop and the access trail from the US6 trailhead up to the loop adds about 800 feet of additional steep climbing.
To reach the northern mountain biking trailhead of Centennial Cone Open Space from Golden, head north on SR93 to Golden Gate Canyon Road. Turn left heading west on Golden Gate Canyon Road for 9.5 miles. Veer left continuing west on Robinson Hill Road. Turn left heading south on Camino Perdido for about a mile to the signed trailhead.
Note: The Centennial Cone Open Space Park is open to mountain biking on alternate days. Make sure to check with the park before heading out to find the current schedule. Also, the Elk Range Trail, which is part of the main loop, is closed from February 1 through June 15.
Overall, Centennial Cone Open Space is the 109th most popular mountain bike trail of all 175 mountain biking rides in Colorado.
