Rated: Beginner. (Once you hit the CT, rating goes to Intermediate.) Trail begins as 6.5 miles of service road to the damn. At the end of the service road, you catch singletrack that is rather smooth with numerous switchbacks climbing about 1 mile to the bench and then take a sharp left switchback up to the Roxborough Loop. The Colorado Trail continues straight from the bench above the lake approximately 10 miles to the confluence of the North Fork of the South Platte and the South Platte River. The Colorado Trail continues to Durango.
Directions: From Golden/Denver, take 470 towards Littleton. Exit at Wadsworth Blvd (CO 121). Turn South and go about 4 miles following the signs to the park. Park in the lot on the left. The trail starts on the opposite side of the road.
NOTE: This trail has been closed during the week in 2016 and open on most weekends due to construction. Please check the Denver Water website for more information on closures.
