SILVER LAKE TRAIL
This 2 mile trail ascends from the Silver Lake area at Deer Valley to Bald Mountain and is designated an out and back. During the summer season, this could be done as a descent only via the Sterling Express lift, but the lifts don’t run in the fall. No dogs are allowed on this trail.
Rob’s is newly designated as an uphill only bike trail, making it a perfect Park City hike for fall. You’ll wind through aspens and spruce with a variety of loop or out and back options. Keep an eye out for moose.
While the PC Hill does not have that epic alpine tree coverage Park City is known for, what it does provide is a great viewpoint for the fall colors. From the trailhead, ascend 1.3 miles for this out and back jaunt. Keep in mind there are a number of offshoots of this trail, so try to follow the one most traveled.
