Jacob's Well Natural Area, Wimberley

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).

    Crispy cold water, even on a hot Texas August the water is numbingly cold though you get used to it after jumping into the well. A must jump, though I wish I would have taken goggles as the water is c...  more »

    Beautiful area. Good for a hike or a swim, but reserve your space to swim in advance, or you'll just be hiking (which is okay, but the water looked refreshing)!  more »

    It was a bit smaller than I expected, but it was still beautiful. The water was nice and cool, which was a wonderful break from the 100 degree Texas weather.  more »

    Beautiful park. Absolutely worth a visit. It is a small walk to get to the well but once you are there it is amazing. If you want to swim you have to buy tickets online prior to going. They do not sell tickets on site hence the 3 star review.

    Very relaxing. Make reservations in advance, my wife and I were there with about ten other people, mostly in their twenties. It was a ten minuite walk from the dirt parking lot. The water was crystal clear and clean. The well itself was cool, a twenty foot deep hole in the stream bed. The water was chilly, if you can, go on a hot day.

    Words cannot describe the beauty of this place. The water is always perfect abs it's so unique and beautiful. It's definitely something to put on your bucket list.

    Very good place to enjoy a weekend with family and friends. It's peaceful and calm. Good trekking trail and very scenic place. Careful if you get into water. It's very slippery and there's very deep well on the edge of stream.

    Didn't swim because we didn't have reservations but a cool place. The kids who were swimming. They have an employee who monitors the swimming hole. Plenty of walkways and trails to walk on too.
