of the best recreational waterways in southeastern Pennsylvania. Along its course, it flows through three state parks: Nockamixon, Ralph Stover, and Delaware Canal. The eastern two thirds of its course are the most heavily used, and it presents many varied opportunities for any visitor. Lake Nockamixon is the most visited spot along the creek's course. Boating is the most popular activity, and its main marina holds dozens of sail boats, and rents out smaller boats to visitors, too. Fishing is also a popular activity, and a fishing pier has been set up of the shore of the lake. Visitors can also hike or bike ride around the area, hunt in certain areas, and even camp if planning to stay for more than one day. When high-water conditions exist, normally in early March and late November, the dam at Lake Nockamixon releases surges of water for one day every few months. This turns Tohickon Creek into a whitewater course, and boaters can manage their ways the entire route from the lake to the Delaware River. At the High Rocks unit of Ralph Stover State Park, visitors can rock climb up cliffs or look at the view from atop. A pathway, Ridge Trail, travels along the top of the wide valley from High Rocks and goes south into Tohickon Valley County Park towards Point Pleasant. At its very end, the creek passes beneath Delaware Canal State Park, where prior to the floods of 2004–2005 visitors could walk north all the way to Easton or south all the way to Bristol. The debris caught in the bridge in the adjacent picture is from this same flood that destroyed entire parts of the canal. Reconstruction of the park is currently underway.
