Jacob’s Well Natural Area








Jacob's Well Natural Area is NOT allowing swimming at this time. We are currently in an annual period of aquatic restoration which lasts from October 1st - April 30th of each year. The cool clear water here makes Jacob's Well a unique swimming destination in the Texas summer heat. However, the large amount of visitors we receive during these months can very disruptive to the wildlife that call this area home. This is especially true of the aquatic wildlife of Cypress Creek. Therefore we dedicate the chilly fall, winter, and spring months to habitat restoration. During this period public swimming access is prohibited, but we encourage visitors to come take a peaceful hike and observe the large variety of wildlife that is visible at this time! 

There is no fee or reservation needed to enter the natural area. A fee is only required if you are swimming in Jacob's Well (by reservation only) during the summer. During peak hours over the summer 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. You may call the park ahead of time to check on the status of the parking lot.

Swimming at Jacob's Well Natural Area is allowed from May 1st - September 30th BY RESERVATION ONLY. Reservations for the upcoming 2019 swim season will become available here at this website at a later date. Each reservation guarantees two hours of swimming in Jacob's Well.

  • Jacob’s Well is an artesian spring that releases thousands of gallons of water a day.

Jacob’s Well Natural Area consists of five land surveys that all use the spring as a corner to tie the properties together. These surveys were conducted in 1847 by a prominent surveyor names Bartlett Sims. In the early 1850’s William C. Winters, a San Jacinto veteran and early settler of Wimberley, hiked up Cypress Creek searching for its source and found an overflowing spring. It is said that Mr. Winters exclaimed “like unto a well in Bible times.” Thus it was named ‘Jacob’s Well’. The property changed hands many times over the next 100 years and became a popular recreational destination. Jacob’s Well Natural Area remains a popular recreational destination today.
