Philadelphia Folk Festival
First held in 1962, the oldest continuously running folk festival in the country takes place each year over three or four days in mid- to late August. Arlo Guthrie, Levon Helm, Trombone Shorty, Doc Watson, Taj Mahal, Joan Baez, and Judy Collins are just a few of the artists who have performed here. You can camp on-site. The festival site is 14 miles north of Valley Forge and 35 miles northwest of Philadelphia.
