Jacob's Well is perhaps the longest underwater cave in Texas and an artesian spring that delivers several thousand gallons of water per minute. It acts as the headwaters to Cypress Creek that flows through Wimberley into Blue hole and then to the Blanco River. The Natural Area is one of the most significant natural geologic areas in the Texas Hill Country. Swimming is available in two-hour time slots, by reservation only, from May 1 - September 30. There is a maximum limit of 60 swimmers at the Spring for each slot. Tours are given on Saturdays from 9:00 - 10:00 a.m. Please see the official website for current updates, admission fees and to make a swimming reservation.
