This is the start of the Crevasse Moraine trail system — a series of swooping, non-technical loops that are fun to bike. During the winter you'll want a fat-tire bike for negotiating the packed-down snow, or if the snow gets too soft you might trade your bike in for a set of skis.
Although the loop trails of Crevasse Moraine are a full destination in and of themselves, there's also a connecting trail that takes you south to Long Lake, Matanuska Lakes State Recreation Area, and other components of the Matanuska Greenbelt.
