For Reservations Click On:

Each reservation allows two hours of swimming in Jacob’s Well. We suggest making reservations several weeks in advance to guarantee your swimming trip. Reservations are for a specific 2-hour time block and guests must show up for the time specified in their reservation**. Late arrival is OK and we will hold your reservation until you arrive BUT your time block remains the same and you will have less time to swim.

There is no fee or reservation needed to enter the natural area for a hike and to enjoy nature. A fee is only required if you are swimming in Jacob’s Well (which is by reservation only). 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.

  • The size of Jacob’s Well Natural Area is a little over 81 acres
  • Jacob’s Well is an artesian spring that releases thousands of gallons of water a day.
  • Jacob’s Well is the second largest fully submerged cave in Texas.
  • The source of the water comes from the Trinity Aquifer, which makes its way from an extensive underground cave system.

  • More than 200 Native Indian groups populated Central Texas and were collectively known as the Coahuiltecans. Three of the most prominent Indian tribes that roamed this area are the: Tonkawa, Jumano Indians, and the Comanche Indians.


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.
