A natural area within Stokes State Forest (Branchville, Sussex County, New Jersey), Tillman Ravine retains the primeval beauty of its pine and hemlock forests. A mountain stream, Tillman Brook, flows through the area and rises in a spring along side of the Kittatinny Mountains. When visiting the ravine, you will find large parking lots (along Tillman Rd), no-flush bathrooms, hiking trails, a great stream dopping over waterfalls and down flumes/chutes. The trail and the river eventually lead you all the way down to Buttermilk Falls (Branchville, Sussex County, New Jersey).
