Middle Fork Loop

The feel

Middle Fork Loop is rolling singletrack in the Chugach that links Hillside trailheads in Anchorage. It is rated Intermediate, technical enough to keep you honest and scenic enough to forgive it.

South Fork Creek runs through the valley. The trail is also popular for hiking and walking, and for skiing in winter. Plan on 3.5-4.5 hr for the loop, and keep any dog on a leash, since dogs are welcome on a leash.

Mingo says

Ride between June and September, when the loop is bike season. Expect mud, and expect the route to differ from older maps.
