Just north of Wimberley is Jacob's Well Natural Area, a growing hotspot for adventure seekers or people who just want to check out an unusual geological feature. According to the Hays County Parks Department Jacob's Well is "an artesian spring, pushed forth naturally from the Trinity Aquifer roughly 140 feet below the surface."
Yep, that hole is about 140 feet deep and is connected to the underlying cave structure which result from thousands of years of "slightly acidic rainfall" eroding the limestone rock.
Swimming is allowed though there are no lifeguards on duty and pets, smoking, drinking and - yes - jumping from rocks are not allowed according to their parks flyer but that last one doesn't seem to be well enforced.
