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.
