About this swimming hole
A 140-foot-deep artesian well opens like a blue eye in Cypress Creek, one of the longest underwater caves in Texas. Swimmers float above the well's mouth in impossibly clear 68-degree water, watching the current boil up from the depths. Drought frequently forces the county to suspend swimming entirely, so verify it is open before making the drive.
