The Trinity Alps Wilderness, located in northwestern California, is home to more than 600 miles of trails and encompasses more than 500 acres of land. It is the second largest wilderness area in California after having doubled in size when the 1984 California Wilderness Act was passed. That same year it was added to the Wilderness Preservation System. 

The Rockingham Recreational Rail Trail (Portsmouth Branch) is an east-west, 28 mile unpaved rail trail starting in Manchester, NH (New Hamphsires largest city) and ending in Newfields, NH (a small coastal town). It is one of the longest designated rail-trails in New Hampshire, used frequently by runners, bikers, walkers, and in the winter it serves as part of the networks of major New Hampshire snowmobile paths.
