Wildlife Area
Jacob's Well is a perennial karstic spring in the Texas Hill Country flowing from the bed of Cypress Creek, located northwest of Wimberley, Texas. The 12ft diameter mouth of the spring serves as a popular swimming spot for the local land owners whose properties adjoin Cypress Creek. From the opening in the creek bed, Jacob's Well cave descends vertically for about 30ft, then continues downward at an angle through a series of silted chambers separated by narrow restrictions, finally reaching an average depth of 120ft. Until the modern era, the Trinity Aquifer-fed natural artesian spring gushed water from the mouth of the cave, with a measured flow in 1924 of 170USgal/s, discharging 6ft into the air.Due to development in the area, the level of the Trinity Aquifer has dropped affecting the flow of water through Jacob's Well. In the modern era, what remains visible of the spring is a faint ripple on the surface of Cypress Creek. The spring ceased flowing for the first time in recorded history in 2000, again ceasing to flow in 2008. This resulted in now ongoing measures to address local water conservation and quality. Hays County purchased 50acre of land around Jacob's Well in 2010, in an attempt to protect the spring from development. An additional thirty-one acres was transferred to the county from the neighboring Jacob’s Well Natural Area (administered by the Wimberley Valley Watershed Association (WVWA)), the new, eighty-acre (32 hectares) named the Westridge Tract.The system has been explored and mapped by cave divers of the Jacob's Well Exploration Project and has been shown to consist of two principal conduits. One passageway measures approximately 4500ft from the surface and a secondary one extends approximately 1000ft in length from the point where it diverges from the main conduit. The cave is also an attraction for open-water divers, some of whom are inexperienced with the specialized techniques and equipment used in cave diving, which has resulted in eight fatalities at this site between 1964 and 1984 (seven men and one woman).

  • Good for nature walk. It will be crowded for swimming. No swimming allowed before May 1st
  • Saw this on Facebook so made it a destination. Was interesting but not as cool as I thought it would be.
  • As a naturalist, Jacob's Well is a remarkable visit. Divers would prove to find a neat little challenges. Casual visitors should be advised of the limits to this park, and plan a back up. The staff there is minimal, though helpful. You'll find a cute little town that hosts it, though I recommend buying your day's essentials before taking off. There's not much else to the park outside of the well. Expect there to be a good deal of people and I recommend wearing proper water-footwear due to the algae build up on the ground. It's a neat experience if planned accordingly.
  • Friendly staff, you need reservations to jump in the well but you can get in the adjacent area for free to cool of. I was lucky enough to have gotten when people did not show up for their reservations and was able to buy the passes for that time. It is like a magical place, and pictures fall short of reality, a little rough for people who are un able to walk in hills but i think they can give you a ride if you are disabled, not sure if the entrance would be different, or who to ask.
  • 8 people have died inside Jacob's Well. That being said, very lovely natural area. Reservations open May 1 for the busy swimming season.
