This guide covers 150 boulder problems, ranging from V0 to V9. The boulders are located in Wissahickon Valley Park, in northwest Philadelphia, and most are right along established trails. The rock is mostly schist, and the climbing styles include overhangs, slabs, dynos, and traverses. Easy access, and the proximity to downtown make this an urban climber's dream.
