 Difficulty rating: 8*     Video
                                                        
 Trout Creek Trail:
ATV trail that is also great for mountain biking. Not your typical ATV trail that is rutted, rocky, and torn                                    up, this trail is well built and maintained. 4 miles back to the creek, or you can push on further but might                                    face a lot of deadfall a ways after the creek. Lots of switchbacks and elevation change. To get to the trailhead from South Fork travel West on HWY 160 for approx 3 miles. The trailhead is on the right side of the highway in an open meadow with a livestock loading chute in the middle of it. Difficulty rating: 6*

 Penitente Canyon:
The canyon offers a total change of scenery from typical South Fork trails. Desert, boulders, and slickrock make for some amazing mountain biking, as well as rock climbing. The A-Loop offers great technical riding with some slickrock, and some more challenging "rock options" if you want to test your balance and skill. The B-Loop offers a mellow combination of desert singletrack and jeep roads that winds its way around washes and canyons. The Forest Service is currently adding some new trails for even more riding possibilities.  To get to Penitente Canyon from South Fork travel 14 miles east to Del Norte, at the stoplight turn north on HWY 112, travel approx 3 miles to the sign for Penitente Canyon. Take a left, and travel several miles on the dirt road, looking for the next sign indicating a left turn to Penitente. The parking area is about a mile up this road, and the A loop starts just before the parking area on the road you came in on. The B loop starts above the parking area about 1/2 mile if you take the singletrack from the far end of the parking lot and go left. Difficulty rating: A-Loop 6*, B-Loop 3*.   Video

                                                              

Middle Frisco Trail:
  A beautiful single track that climbs deep into the high alpine terrain of Colorado. 7 miles one way, 14 miles out and back.
  This ride begins at the confluence of west and middle Frisco Creek. From here the single track parallels Middle Frisco Creek   all the way up to Frisco Lake. Or you can take the West Frisco ATV trail up (a slightly easier climb), and the singletrack  Middle Frisco trail back down.  The trail begins at 9,500 ft and climbs up to 12,000 ft at the lake. 
  The first half of the trail has a smooth flow though the aspens and pines as it meanders up, down and around while maintaining   an overall steady climb.  Riders can expect to negotiate a few stationary rocks and tree roots.  As Frisco Creek valley gets      steeper, the trail has a series of switch backs that are a little loose and rocky but all rideable. The trail here is more technical    because it is looser, rockier and more exposed than the lower part.  As you near the lake, you will emerge above the tree line  and behold some amazing Colorado views.  Once reaching the lake, you are ready to reverse your tracks and begin 2,500  vertical feet of pure downhill fun!
 To get to Middle Frisco Trail from South Fork, take highway 160 east approx 14 miles to Del Norte.  Drive through town
  until you see the car wash on the right or South side of the road.  Just after the car wash take a right on French Street or  County Road 13.  This road starts out paved and turns into a well maintained dirt road accessible by a low clearance 2WD  vehicle.  Continue on this road for about 9 miles where you will come across the signed trail head.  Difficulty rating: 5*, or just ride the lower part for a difficulty rating of 3*.   Video

Wolf Creek Pass HWY 160:
Wolf Creek Pass is a great way to challenge yourself if you are looking for a scenic road ride in South Fork. 19 miles from town to the top, with about 2,600 ft. elevation gain. Most of the route to the top of Wolf Creek has a great 4 ft. shoulder, but there is one 4 mile stretch where the shoulder is virtually non-existent. Thankfully on this stretch the speed limit is only 50, so its generally not a problem. The steepest part of the road on the east side of Wolf Creek is about a 6% grade. To get to this ride, simply head west on HWY 160 from South Fork, and immediately realize you are climbing! Difficulty rating: 7*        Video
                       

                                                         
HWY 160 South Fork to Monte Vista:
HWY 160 from South Fork to Monte Vista is smooth, fast, and relatively easy with a shoulder wide enough to ride 4 bikes wide most of the way! Mostly flat with a few rollers, brand new pavement. Great mountain views the whole way as you ride through farm and ranch country. Approx 30 miles one way to Monte vista, or 60 miles round trip. If you ride back to South Fork, be prepared for a headwind typically blowing through the San Luis Valley which can range from a gentle breeze to a stiff wind, especially in the Spring and early Summer. To get to this ride, simply head east on HWY 160 from anywhere in South Fork. Difficutly rating: 1*
