Over 40,000 copies of 50 Hikes of Eastern Pennsylvania sold in its first two editions, under the authorship of Carolyn Hoffman. Now Tom Thwaites, Pennsylvania's preeminent hiking authority, has taken over the guidebook to this popular area - selecting 50 hikes and rewriting the text from scratch in his clear, concise prose. The hikes range from 1 to 14 miles in length. Each is described thoroughly, including driving directions to the trailhead, a clear map, and a verbal portrait of the area's history, geography, and wildlife.
