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 spring is located on the property of Jacob's Well Natural Area, managed by the Hays County Parks Department. The visitor entrance for JWNA is located at 1699 Mt. Sharp Road in Wimberley, Texas. The 12-foot diameter mouth of the spring serves as a popular local swimming spot. From the opening in the creek bed, Jacob's Well cave descends vertically for about 30 feet, then continues downward at an angle through a series of silted chambers separated by narrow restrictions, finally reaching an average depth of 120 feet. 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 170 US gallons per second, discharging 6 feet into the air.
