Cedar Sink Trail
Cedar Sink
A large karst sinkhole in the southwest of the park, where a trail with stairs descends to the valley floor, and a river emerges from underground before disappearing again.
Cedar Sink is one of the most spectacular surface karst landscapes in the park: a huge collapse basin about 300 meters wide, surrounded by steep cliffs and dense woodland. An underground river flows out from one opening at the base of the valley, surfaces briefly in the depression, then slips back into a crevice on the other side, offering a clear view of the groundwater system of the Mammoth Cave area. The trail is about 3 km round trip, with steps and observation platforms, and takes about 1.5 hours. It is free, and parking is along Cedar Sink Road in the southwest of the park.
