Southwest of Montrose, the Spring Creek Trail is a challenging 10 mile one-way trek in the Uncompahgre National Forest. The Spring Creek Trail is a doubletrack mainly used by ATV riders and dirt bikers with 2,500 feet of climbing.
To reach the mountain biking trailhead from Montrose, head west on SR 90 for 2 miles. Turn left following SR 90 for 1 mile. Turn right following SR 90 for 0.25 miles. Turn left on Dave Wood Road (aka 6250 Road) for about 6 miles to the the National Forest boundary. You will see a trail coming out the road with no parking - that is part of the Buzzard Gulch trail system. The informal parking for the Spring Creek Trail is located just past that trail. There is room for about a half dozen cars.
Start riding west on FS536 (a doubletrack) for one mile. Turn right onto another doubletrack and follow along the ridge for another mile and then drop into a steep canyon on singletrack. At the 5.5 mile point, veer right at fork and continue on wide singletrack through lush benches and dense aspen groves. Continue to climb on singletrack and cross several streams into thicker timber. At mile 10.5, turn left on doubletrack and mountain bike ride another half mile to Divide Road. Either turn around and mountain bike ride back the way you came, or turn left on Divide Road to Dave Wood Road. Turn left on Dave Wood Road and return to vehicle. Road option is 13 miles, but is easier.
The nearest airport is Montrose Airport (MTJ) that has regular flights to Denver, Dallas and Houston.
