One of the best backcountry loops you'll find in Wyoming.

Louis Lake Rd. is typically closed until the first week of June. Snow may not permit riders from accessing the upper sections of this trail until late May.


This is a classic example of a backcountry Wind River Range ride. This ride skirts the Popo Agie Wilderness Area, climbing through aspen and lodgepole stands, along a number of pristine mountain creeks and descends a beautiful river canyon. It offers something for those seeking a longer, more technical mountain bike ride in the Lander area.

Need to Know

Keep in mind that sections of this ride are remote and cell phone service is not a guarantee. For more info, see the Middle Fork Trail description.


Beginning in Sinks Canyon Campground, start with a pedally climb on the Brewer's Trail to the upper meadows of The Catalyst Trail. This trail is all brand new, extremely well-benched, 100% singletrack with some sections reaching above 15% grade. It's a nice reprieve from the climb as you pedal through the non-technical upper meadow sections of The Catalyst Trail. Top out at the Fossil Hill parking lot (there's a single pit toilet there).

From there, continue up the Louis Lake Rd., following signs to Worthen Meadow/Reservoir Campground.

From the Worthen Meadow Trailhead, begin a short but technical, very rocky climb along the Middle Fork Trail. The descent from Sheep's Bridge to the Middle Fork Trail is rocky (ranging from gravel to baby heads to refrigerator-sized boulders) and technical, requiring some hike-a-bike sections and/or advanced bike handling skills.

The Middle Fork Trail to Popo Agie Falls is a popular hiking route. You'll likely meet hikers and possibly dogs on the trail. Please be courteous and yield to uphill traffic. Carrying a bell is not a bad idea as there are a number of high-speed sections on this trail. This loop is best ridden on weekday mornings or evenings.

took a little while to find trailhead and then the first main left up the the hill on new trail. The the rest of the ride was fun. — 5h 42m

The climb is as good as it gets, but the suggested decent is not worth it, just miles and miles of loose rock. Instead of doing the loop, I'd suggest doing the climb and turning around when you get to the road. Aug 28, 2017
