About Foster Falls

Foster Falls is the flagship sport crag of South Cumberland State Park — 180+ bolted routes on hard Cumberland Plateau sandstone along a compact cliffline near the 60-foot Foster Falls waterfall, an hour northwest of Chattanooga. Cliff sits under mixed forest with sectors of varying aspect — chase shade in summer, sun in winter. Waterfall spray keeps humidity high near the base; some sectors seep for days after heavy rain — climb the exposed White Wall or Right Bunker first after wet spells. Cumberland sandstone wet-rock ethic. — you'll get a confirmation number to keep with you. Gate closes 30 min after Central sunset. On-site 26-site campground (reservations required). Rules: no rappelling in climbing areas, no top-rope from fixed anchors, leashed dogs only.
