Most people ride this trail from the Sun Peak Recreation Center, and connect with Mid Mountain or Ambush
for a great loop. From the Sun Peak Recreation Center, you ride up DuBois and Collins to reach Rob's.
If you ride from the trailhead, at the parking area off Bear Hollow Rd., Rob's trail is a fairly steep grind through the pine covered, north face of the ridge. The trail surface is mostly smooth and tacky, with some rocky technical sections on the straights. At the top, the trail emerges at a saddle and crosses over the the south face of the ridge, then drops you at the top of Ambush
and the Mid Mountain Connector
for a great downhill through Canyons Resort, or ride the Mid Mountain Connector
up to the Mid Mountain trail, which takes you all the way to Deer Valley with plenty of downhill options along the way.
