Maryland is one of the most densely populated states in the Union, yet miles of hiking trails weave throughout its natural areas. This is a guide to the trails and recreation areas, accessible to hikers through the Washington DC area. Hikes range from a 1.2-mile ramble in the Swallow Falls State Park to a four-day backpacking trip across Maryland's width. An overview chart at the beginning of the book provides information on the 50 hikes at a glance. Each hike description includes directions to the trailhead, a detailed account of the route, a map, and asides on natural and historical points of interest.
