Stump Hollow

This is a beautiful forested ride on pristine singletrack, near the top of Logan Canyon. As an out-and-back, it's 5.3 miles each way, with about 1600 vertical feet of climbing. It can also be done as a shuttled ride, or as a big 16.5-mile loop. It's an easy technical ride overall, rating an early-intermediate for skills, and the climbing rate is pleasant. Stump Hollow is part of the GWT (Great Western Trail).

The singletrack meanders uphill through aspen and fir. On the lower mile there are some stunt opportunities such as jumping berms and a nice log drop. Eyeball them on the way up so you're ready on the way down. There are cheater routes around the stunts.

Most riders simply ride the lower portion of Stump Hollow as an out-and-back, sometimes doing a couple of runs over the jump area.

Heading downhill. The lower mile has many jumps. If you're not into air, you can slow down and simply roll over them.

There are three other ways to do this ride:
(1) Shuttle. Drive to Bear Lake Summit at the tip-top of Logan Canyon, then navigate the gravel roads to where the Stump Hollow (GWT) forks off the road above Peter Sinks. Note that the wooden trail sign is well off the road, so GPS is suggested if you don't have a local guide.

(2) Summit Loop. Start up the trail, then at mile 0.3 exit the trees to your right and find an old road heading east through the sage flat (the connector to this road is very faint). Follow this DT until it joins the highway across from the Swan Flat road. Ride along the highway to the Bear Lake Summit, then turn L onto the dirt road and navigate to the trailhead.

(3) Little Bear Creek. Haven't done this, but there's a DT behind the USU research station (east side of US-89 just downhill from the Tony Grove Lake turnoff) that turns into ST heading up Little Bear Creek . My topo map shows that if you stay on the main trail along the creek, you'll turn L on DT about 1-1/2 mile from Stump Hollow's upper end.

Most of the ride is in deep forest, so there are only occasional views over the nearby mountains. Many riders turn around at the ridgetop at mile 4.5, but I think the rock-slab riding in Peter Sinks is a fun addition. As you climb the east side of Peter Sinks, watch for the big rock monuments that mark the trail. The slab rock makes the trail harder to see.

Typical riding view higher on the mountain, where large firs alternate with aspens and occasional brush meadows.

View across the valley as we peek between the fir trees that line the trail.

Bottom Line!

This is a great ride that I can recommend highly. It will accommodate (and satisfy) a wide variety of skill levels. The altitude and shade keeps it fairly cool on a summer's day, but it's a great ride for close-up inspection of fall colors. My suggestion is the out-and-back.

Peter Sinks. Look for the next big "monument" as on the left here, and you'll find the trail up to the TH at the road.

Getting there: In Logan, turn east at 400 North on US-89 towards Logan Canyon (about 2 miles). After you enter the canyon, drive 24.5 miles, almost to the top. Turn left toward Beaver Mountain Ski Area and bike trails, then immediately turn right into a parking area. There's a bathroom north of the parking. From the parking lot, go south across US-89 to the south side of the road. From the spot where the Beaver Mountain road forks off US-89, ride 100 feet down the canyon and you'll spot the singletrack heading off into the brush on your left. To shuttle the ride, drive another five miles up US-89 to the Bear Lake Summit and turn right on gravel road. (Driving directions above.)
