Jacob's Well: swimming status and access

Jacob's Well is a deep artesian spring near Wimberley, in the Hill Country southwest of Austin, that in a normal year opens for reservation-only swimming from May through September. That hasn't happened since 2022: Hays County has suspended swimming every season since because of low flow tied to drought and heavy groundwater pumping in the surrounding aquifer, and as of September 2026 the water stays off-limits with no reopening date set. The natural area around the spring is a different story, open daily for hiking at no charge. It's one of the stops in our swimming holes in Texas guide, alongside several sites that still charge admission or require a reservation to get in the water.

No sourced coordinates are available yet for swimming holes — there is no government register for this category to map against (see methodology). Every spot is listed in the table below with directions in the text.

Swimming status

Hays County closed Jacob's Well to swimmers on June 29, 2022, after spring flow dropped toward zero and the county judged the water unsafe because of high bacteria levels, other pollutants and poor visibility. The county has renewed that closure every season since, citing drought and increased groundwater demand in the Trinity Aquifer, and as of September 2026 it remains "cancelled until further notice" (Hays County Parks Department). The spring ran strongly for a short stretch after heavy rain in July 2026, then receded again, and reporting on the site describes a reopening as a long way off (Houston Public Media, August 7, 2026).

None of that affects the hiking trails. The natural area stays open daily, and the roughly 3 miles of trails around the spring cost nothing and don't require a reservation, even during the years-long swim closure.

Access and hiking

Jacob's Well Natural Area is open from 8 a.m. to 6 p.m. daily, with no entry allowed after 5:30 p.m., and charges no admission or parking fee (Hays County, Jacob's Well Natural Area). The main trail to the well itself runs a short distance from the parking area, and the wider trail network adds a few miles more if you want to explore beyond the spring. The ground right around the well can be steep and slippery, worth keeping in mind even without swimming in the mix.

Before the 2022 closure, Hays County ran swimming as a timed, reservation-only activity during the May-through-September season, similar to the system still in place at Blue Hole in nearby Wimberley. That system is currently dormant along with the swimming itself; check the county's own page before assuming any part of it has restarted.

The spring and its cave system

Jacob's Well formed where groundwater pushes up through a break in the Trinity Aquifer's limestone, and the visible pool is only the entrance to a much larger underwater feature. Below the surface, the shaft opens into a network of flooded cave passages that has drawn technical cave divers for decades and has a well-documented history of diver deaths, including experienced divers who pushed into the cave's far chambers without a safety line (Texas Monthly, "Down in the Depths"). None of that risk applies to a visitor standing on the bank during the current closure, but it's part of why the site is treated with more caution than a typical swimming hole even in years when the surface water is open.

How this guide was researched

This page was compiled from the Hays County Parks Department's official announcements and park page, Houston Public Media's 2026 reporting on the drought-driven closure, the USGS gauge listing for Jacob's Well Spring, the Texas Department of State Health Services, the CDC and Texas Monthly's account of the site's cave-diving history. We haven't visited this site ourselves. The swimming closure has been renewed every season since 2022 and could change; verify current status with Hays County before planning a visit. Last checked September 2026.

Before you go

Check Hays County's own page before a visit if swimming is the point of your trip; the closure has now run for multiple consecutive seasons and there's no fixed timeline for it to lift. How a closure like this one works, and why the county's own page overrides whatever a map app shows, is covered in our access and legality guide. If you'd rather not gamble on the closure lifting, our swimming holes finder covers sites in Texas and other states where the water is open this season. If you're coming for the trails instead, plan around the 8 a.m. to 6 p.m. window and the steep, slippery terrain right at the well itself.

Even during seasons when surface swimming is allowed, the cave system below is for trained, permitted technical divers only. The people who have died here were divers who went past the entrance shaft into the cave, some of them experienced. Treat the well's edge with respect regardless of what the water level looks like on a given day. For whenever the surface does reopen, our swimming hole safety guide covers depth checks, cold water and the other basics.

The low flow and warm, stagnant water behind the current closure are also the kind of conditions that suit Naegleria fowleri, a rare but usually fatal amoeba found in warm freshwater above about 80°F; Texas has the country's highest documented case count. The risk is very low in absolute terms, and infection only happens when contaminated water is forced up the nose, typically from jumping or diving, not from swallowing it. Whenever swimming here does reopen, the Texas Department of State Health Services recommends holding your nose or using nose clips when jumping in and avoiding stirring up bottom sediment (Texas DSHS, PAM FAQs; CDC, preventing Naegleria infection when swimming).

FAQ

Is Jacob's Well open right now?

The natural area is open daily for hiking, 8 a.m. to 6 p.m. Swimming has been closed since June 2022 and remains closed as of September 2026, with no reopening date set.

Why is Jacob's Well closed?

Hays County suspended swimming because of low spring flow linked to drought and groundwater pumping in the surrounding aquifer. The county has renewed the closure every year since 2022 rather than lifting it.

Can you still visit Jacob's Well if you can't swim?

Yes. The hiking trails around the spring stay open year-round at no cost, and you can view the well from the bank even while swimming is off-limits.

Is Jacob's Well dangerous?

The submerged cave system below the visible pool has a documented history of diver fatalities and is limited to trained technical divers, even in seasons when surface swimming is open. The current closure means no one is entering the water at all.

Do you need a reservation to visit Jacob's Well?

Not for hiking, which is free and open without booking. Swimming normally required a reservation during its May-through-September season, but that system isn't in use while the water stays closed.
