Description
Mine Hole Falls (also known as Hewitt Falls) is a small but powerful waterfall along the Wanaque River in West Milford. Despite being located on public land in Long Pond Ironworks State Park, the state park service restricts access to the waterfall. Mine Hole was a popular spot for cliff jumping, but after a death in 2016, the state closed the area and the waterfall indefinitely. State park police patrol the area and issue citations. Unfortunately, Mine Hole Falls is a legitimately good waterfall, and it is a shame the state park service decided to close the area completely instead of finding alternative solutions to manage the risks.
For those who still want to visit Mine Hole Falls, there are many impossible-to-miss signs stating that the area is closed and trespassers will be prosecuted. When the waterfall was initially closed, it was dangerous for two main reasons:
- Despite being only 16.2 feet, the waterfall is extremely powerful. The best comparison in the state would be the Boonton Falls, which is similarly short but with a very high volume of water going over.
- There is a literal “mine hole” below the waterfall. It is possible to become trapped in the mine below and drown.
Since the initial closure, the conditions have gotten more dangerous. In late 2024, the Jennings Creek Wildfire burned through the area of the waterfall. Although the park is open again and trails have been cleared, the waterfall area is not technically public access, and wildfire hazards likely remain, including loose soil and dead trees.
For those who insist on visiting, the waterfall is easily accessible, can be heard from nearby trails, and the excessive signage around the area points directly to it.
