Northwest of Durango, the Clear Creek Trail (#550) is a 6 mile route open to off-road motorcycle trails riding. It starts at 10,200 feet and descends to 7,400 feet.
Access #1: Heading north on Main Street in Durango, turn left (west) on 25th street until it turns into Junction Creek Road (FDR #171). Follow this road for approximately 22 miles. Trailhead is on the north side of the road.
Dropping 2,800 feet from Junction Creek Road with very little uphill in between, this trail is all downhill! Basically it runs next to the creek, so there is ample water - although it should always be filtered, to avoid Giardia. Fishing is also a possibility. There are several camp spots along the way, especially near the bottom of the trail. There are bears in this area, so caution should be used. There is no bridge crossing Hermosa Creek.
Note: As of October 2008, it has been reported that this trail has been fallen into disrepair. It may no longer be open to motorized vehicles, so check with the NF before driving to the trailhead.
Note: Colorado residents must register their off-highway vehicle with the Colorado State Parks (303) 866-3437. Non-residents are not required to register in Colorado, if they are registered in their home states. All off-highway vehicles must have an approved muffler and spark arrester. These requirements are subject to change so make sure to contact the Colorado State Parks prior to using your off-highway vehicle.
Overall, Clear Creek Trail is the 34th most popular dirt bike trail of all 93 dirt biking rides in Colorado.
