    Jacob's Well is closed for the foreseeable future and swimming is currently not available.

    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 45 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.

    There is no fee to park or enter the natural area. A fee is only required to swim in Jacob’s Well. During peak hours the parking lot may reach capacity, at that time we will begin to turn away all visitors without reservations until there is more space available.
