About this spot
Located in rural Maryland northwest of Washington DC, this former quarry is now a water-filled jumping destination spanning roughly 100+ yards long and 50 yards wide, with sheer rock walls suitable for safe jumps. Access requires a 25+ minute woodland hike and sits on private land, so thorough preparation is essential—visitors unfamiliar with the route risk getting lost and encountering unwelcoming property owners. Spring visits are preferable due to dense vegetation in late summer creating significant poison ivy exposure. The forest canopy opens directly onto the quarry bank, creating an isolated atmosphere. Multiple people typically frequent the site. Three primary jump locations exist, with additional ledges available for exploration. A large rock formation accommodates 3-4 simultaneous jumpers and reaches approximately 25 feet. From this platform looking left, two additional marked spots are visible with spray paint indicators, measuring around 45 and 55 feet respectively. Directions from I-270: Take exit 22 toward Barnesville. Continue on Old Hundred Road approximately 3 miles, turn right onto Comus Road for roughly 2 miles, then left on Mt Ephraim Road about 2 miles. At the road's rightward bend sits a small local train station parking area. Cross railroad tracks and head right approximately 300 yards, then enter woods moving parallel to the tracks until locating a left-turning path leading to the quarry. The route passes through two agricultural fields—at the first, walk its perimeter downhill to the lowest point and traverse straight across. Watch for a distinctive tree-branch archway marking the second path. This path crosses a creek; use the nearby embankment to navigate the other side. Ascend the steep hill beyond; a right-branching path descends to lower jumps while the main route curves around to higher platforms. Remember the return route carefully as this remains private property.
