The County is now running Jacob’s Well and the surrounding area as a public natural area. The natural area features an underground cave and artesian springs that form a beautiful, but small, pool. They have a guided tour on most Saturdays that discusses the hydrologic features of the well, which forms the headwaters of the gorgeous Cypress Creek that flows through Wimberley. This is a great place to bring the kids to learn about the natural environment in this area and to take a dip in the icy water. However, you need to make sure that the water is flowing at a pretty good clip to really enjoy the place so call before coming out to check on the conditions. Also, this is a pretty small area for swimming so it is best to come out early.
