There is no shortage of hiking trails in the National Park System. From coastal walks and boardwalk trails to trails that run the ridges of the Teton Crest Trail in Grand Teton National Park and the wildly popular hike to the top of Old Rag in Shenandoah National Park, the options can be overwhelming even if you had endless time to explore the parks. It might come as a surprise to those who view Yosemite National Park as an iconic valley and a grove of soaring sequoias, but there are more than 800 miles of hiking trails in that park. And to get a feeling for those trails, we’re joined today by Elizabeth Wenk, the author of the 6th edition of Your Complete Hiking Guide/Yosemite National Park from Wilderness Press.
