Beautiful scenery and lots of trails for hikers and bicyclists. The Andover Loop Trail (orange blazes) offers 8 miles of varied scenery, part of which is a rail trail (flat), some moderate hill climbs and then a walk around Lake Aeroflex. Make sure to stop by the Visitor Center to pick up a trail map, use actual flush toilets (if needed) and learn a little about the interesting history of the park.
