Short, rooty trail broken up by creek crossings and rocky climbs. Do watch for pedestrians, as this is a multi-use trail (and two-way.)

A borderline trail between easy and intermediate, Huntsville State Park is a rare trail that manages to be more descent than ascent. The downs are fun and fast, the rises are carefully gradual, and there are boardwalks over the swamps.
