Current Chugach State Park regulations (11 AAC 20.050 (c)(1)) allow fat-tire bikes (3.5" or larger tire width) between November 15 and March. Biking with tires smaller than 3.5" width is prohibited year-round.
Be bear aware in this area.
This trail connects to Powerline Pass
at the south end and Prospect Heights trailhead at the north end. The trail descends south to north or climbs north to south. From Prospect Heights, go up Wolverine Bowl trail then turn right on Middle Fork when climbing out of the creek valley; from Glen Alps, head "up" Powerline Pass
to the south, then take the first available left turn off the trail.
I usually ride this trail by Parking at Prospect Heights, riding up Flattop Flyer
, then riding down Middle Fork, or riding up Middle Fork then down Flattop Flyer
Middle fork is nice, narrow singletrack with good views of Anchorage on much of the trail. The trail has a few board skinnies as well as some wood steps near the intersection with Powerline Pass
. Be careful with your speed heading downhill, as there may be hikers heading up.
