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.




Jacob’s Well Natural Area is proud to partner with the Hays County Master Naturalists, who volunteer their time at the park and lead guided tours. Regular Saturday morning guided tours are suspended over the summer and will begin again on September 2nd.  Tours by a Master Naturalist or member of the staff are still available upon request.
