Jacob's Well Natural Area is currently open to the public during regular open hours. Swimming and water access are currently not permitted.

Jacob's Well is the second longest submerged 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.

Free public guided tours are offered each Saturday from fall - spring (no summer tours) each year and they take place from 10am-11am. Our Nature Center exhibits are open to the public on Saturdays and Sundays from 10am-3pm right now. Jacob's Well is normally open for swimming from May 1–September 30 by online reservation only. However, public swimming access in Jacob’s Well is contingent on precipitation and groundwater flow. Due to low water levels and flow, the 2024 swim season has been suspended until further notice

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.
