Van Campens Glen Falls
Van Campens Glen Falls is the terminus of the Lower Van Campens Glen trail hike near Walpack, NJ. The top of the falls features a deep, large pool that cascades down a slanted rock face. The areas surrounding the upper pool require extreme caution as this area has been responsible for numerous accidents and deaths in years past. 
 The trail itself features a densely covered hemlock ravine that hosts various delicate plants and species of wildlife. The root systems at the base of many of the hemlocks have been damaged due to high foot traffic in the area. This, in addition to storm damage and a lack of funding, has led the National Park Service and Department of the Interior to close the Lower Van Campens Glen trail indefinitely, due to public hazard, as of Spring 2019.
