Bunchgrass Trail
via White Pine Lake
The Bunchgrass Trail starts at Tony Grove Lake in Logan Canyon. This very pretty singletrack trail is 11.2 miles long (if you do the little loop at White Pine Lake). With the shuttle option, it's suitable for intermediate riders, although some might struggle on the rocky areas. Expert riders will hammer this one and love it. There's a moderate amount of climbing, but the ride offers miles and miles of not-too-technical high-speed downhill singletrack.

The ride can be done as a shuttle by leaving a car at the bottom of the Tony Grove road, or as a 19-mile loop by riding the bike up the 7-mile paved road to the lake. You'll do the White Pine Lake trail , but instead of returning to Tony Grove, you'll descend to the highway in Logan Canyon first along White Pine Creek, then via Bunchgrass canyon.
The singletrack trail starts from the Tony Grove Lake parking lot and climbs 800 vertical feet over 2.5 miles -- a fairly pleasant rate of climb. There are a few spots of embedded rocks for a little line-picking practice but most of the climb is on buff trail.

You'll be riding through a fir and aspen forest with many small meadows. The ride has a bit of everything: Grand vistas, a pretty lake, a few slightly-tech uphill spots, some slightly tech downhill spots, and a lot of straight-ahead warp-speed cruising.

Once you reach the peak altitude of 8800, you'll descend a couple of switchbacks toward White Pine Lake. There are a few rock challenges here, but each one is short, forgiving, and very doable. A fun start to the downhill.

As you reach the 4-way near the lake, go left down to the lake then loop clockwise along the lake and around the camping area. You'll see a few trails -- and these may change based on camper and cattle traffic -- but just mosey up and east from the north end of the lake and you'll find yourself on a southbound trail that returns you to the 4-way. Now go left.

Soon after leaving the lake, you'll drop a moderately steep area with plenty of round river-rocks. Just keep your brake action light and surf your way down.
The trail crosses White Pine Creek, then begins a long smooth singletrack descent. Sage meadows alternate with wooded areas. At mile 7.5, keep right at the fork where the White Pine trail goes downhill and Bunchgrass turns a bit uphill.

Now come two stiff hike-a-bikes, the 2nd worse than the 1st. At the top of the second, you'll drop a steep loose section then begin a high-speed cruise toward the bottom of Bunchgrass Creek. One of our riders hit 29 mph. The singletrack is narrow, straight, and smooth.
This bottom two miles just flies by: whiz through a meadow, wind through the trees, into another meadow. Very pretty; great fun.
