Check out this ride on Bearberry!
Bearberry Bluff is a dirt, single-track trail that carves a flowing path through forest, banking around neatly groomed corners in a 1.1 mile loop. Bearberry Bluff, Bearbottom, and Rootbear are Mat-Su Borough trails. The latest Borough additions include Fox Run and Foxtrot trails, all north of Long Lake.
These easy to moderate single tracks are a fun, hoot-worthy ride. In the fall, leaves spatter the trail with color. The Bear and Fox trails tap into a network of some 33 miles of trails within the Matanuska Greenbelt network. The Greenbelt are loops of trails between the Palmer-Wasilla Highway, the Glenn Highway, Parks Highway, and Trunk Road. There's four land owners collaborating: the Matanuska-Susitna Borough, University of Alaska-Mat-Su College, University of Alaska Fairbanks-Experiment Farm, and the State-Matanuska Lakes State Recreation Area. Some 100 posts with 300 directional signs and 12 gateway posts with small maps help you get around this undulating, looping, and curving trail network.
