Setting On the water

A collapsed grotto with a 50-foot waterfall spilling into a jade-green natural pool surrounded by massive limestone overhangs draped in ferns and moss. It is one of the most stunning natural swimming holes in Texas and kids are awestruck the moment they see it. Two things decide whether the trip works. Reservations are mandatory every day of the week and sell out well ahead. And swimming is a separate question from entry: after heavy rain the bacteria count rises and the county closes the water, sometimes at short notice and sometimes for weeks, so a reservation buys you entry and never guarantees a swim. The preserve stays open for hiking either way, and the grotto is worth seeing dry. Call the daily status line before committing to the drive. The quarter-mile trail from the parking area descends steeply, so it is not suitable for very young children or strollers.
