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.Plan to see Jacob's Well Natural Area and other attractions that appeal to you using our Wimberley trip maker app .
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.
Jacob's Well Natural Area Reviews
Simply beautiful here. They only let a certain number of people into the well, and you have to make a reservation. This made the experience enjoyable as it wasn't crowded. We were able to swim in the hole and jump into it from the rocks overhead. The water was crisp and clear. They've kept this area very nice and mostly natural other than the path to the water.
Looked like a refreshing place to go swimming but we did not have reservations to swim. The nice attendant allowed us to walk down the trail; for that I’m grateful so we could at least visit the area. Along the trail you’ll find signs that inform you of the history behind the area. Now that I know I need reservations to visit Jacob’s Well I’ll go back. Can’t wait!
