Sink Hollow is a narrow ATV trail north of Beaver Mountain near the top of Logan Canyon. The Sink Hollow trail itself features 5 miles of downhill through pine and aspen forest. Ride it as a 13.5 mile loop with 1300 feet of climbing by taking the dirt Beaver Creek road uphill.
The descent down Sink Hollow would rate advanced technical due to some rock gardens and steeper loose slopes. The hairy spots are easy to see in advance, so intermediates can do this route by hiking through the scary spots. Overall, it's a fairly quick trip, about 90 minutes for a skilled rider.
You're surrounded by pine, aspen, and fir. It's a very pretty ride, especially in the fall. On the uphill along Beaver Creek, you'll share the dirt road with crowds of ATVs and SUVs. Not a problem. There's plenty of passing room, and it was surprisingly quiet and non-dusty as the motorheads rolled by.Primitive camping spots are sprinkled along the road. At 4.1 miles up the road, you'll pass the Beaver Creek Campground (with bathrooms). A bit past the campground, pass the smaller road to Swan Flats -- another ride option -- on your right.
180-degree view from the north end of Gibson Basin. As you enter the basin, the left fork is smooth and fast. The smaller right ATV tread is lots more fun, and is the "official ride." The two tracks rejoin at the south end.
