About this swimming hole
A collapsed limestone grotto with a jade-green pool fed by a 50-foot waterfall, one of the most photographed swimming holes in Texas. Spring water keeps the pool cool even in August, and the towering overhang shelters ferns and cliff swallows. Swimming is sometimes suspended after rains when bacteria levels spike, so check conditions before you go.
