About Jacob’s Well
Jacob’s Well is one of the most striking sights in the Texas Hill Country: a crystal-clear blue spring opening in the bed of Cypress Creek, fed by the Trinity Aquifer. This artesian vent is the headwaters of the creek and drops into one of the longest underwater cave systems in Texas — from the limestone rim, you look straight down into deep, blue water.
The well sits in an 81-acre county natural area, so even while swimming is suspended there is plenty to do: walk the trail down to the spring, picnic, join a guided nature tour or watch for birds. Swimming here is a privilege the county opens only when water levels allow, in reserved two-hour blocks — check the current status before planning a trip around a swim.

Access & fees
Visiting the natural area itself is free — you can hike in and view the well without a reservation or fee, any day from 8 a.m. to 6 p.m. Swimming is different: it needs a paid online reservation (two-hour blocks, about 40 people per block) in the May 1–September 30 swim season, at $12 for adults and $9 for children 5–12, seniors, service members and Hays County residents. Right now, though, all swimming is cancelled until further notice because of low water levels.

- Swimming is currently cancelled until further notice due to low water levels — do not enter the water

- The trail down to the spring is roughly 1,300 feet — wear sturdy footwear; strollers are not recommended
- Always check the county’s current status before visiting — swimming opens and closes with water conditions
