Updated January 11, 2022

COVID-19 Update: Jacob’s Well Natural Area is currently open to the public. The Nature Center remains closed at this time.

Know Before You Go!

    • Jacob’s well natural area is currently open to the public during open hours (8 a.m. – 6 p.m. daily).
    • Reservations are required for water access at Jacob’s Well.
    • No dogs, glass, alcohol, or drones are permitted in the natural area.

    • We recommend all visitors follow the most up-to-date CDC guidelines while visiting the park.

Jacob’s Well Natural Area is NOT allowing swimming at this time:

We are currently in an annual period of aquatic restoration which lasts from October 1 – April 30 of each year. The cool clear water here makes Jacob’s Well a unique swimming destination in the Texas summer heat. However, the large amount of visitors we receive during these months can be very disruptive to the wildlife that calls this area home. This is especially true of the aquatic wildlife of Cypress Creek. Therefore we dedicate the chilly fall, winter, and spring months to habitat restoration. During this period, public swimming access is prohibited but we encourage visitors to come take a peaceful hike and observe the large variety of wildlife that is visible at this time! 

Swimming in Jacob’s Well:
Reservations for the 2022 swim season (May-September) will re-open in early/mid-March. We will post the info on this page and on our social media pages.

Jacob’s well is open for swimming from May 1  – September 30 by online reservation only.

We do not have a waitlist for swimming. Reservations are for a specific two- hour time block and guests must show up for the time specified in their reservation. Late arrival is okay and we will hold your reservation until you arrive BUT your time block remains the same and you will have less time to swim.

Things to do at the preserve: 

There is no fee to park or enter the natural area. A fee is only required to swim in Jacob’s Well. We are currently in a period of aquatic restoration in which swimming is prohibited. Hiking, birding, picnicking, geocaching, photography and viewing the spring are permitted within park hours, with no reservation needed. If you are interested in a tour of Jacobs Well Natural Area, then please view the #Tours section below.

Recommended Hiking Hours: 8 a.m. – 10 a.m. every day
Entrance for hiking and viewing the spring is not guaranteed outside of the recommended hiking hours. This is based on park capacity. We strongly recommend visiting the park during our recommended hiking hours to beat the heat and crowds.

A Few Facts About Jacob’s Well

    • Jacob’s Well Natural Area is a little over 81 acres.
    • Jacob’s Well is an artesian spring that releases thousands of gallons of water a day.
    • Jacob’s Well is the second-largest fully submerged cave in Texas.
    • The source of the water comes from the Trinity Aquifer, which makes its way from an extensive underground cave system.
    • The deepest part of the cavern system is 140 feet deep. The main cavern length is 4,341 feet and the secondary cavern, which branches off the main cavern, is 1,314 feet in length.
    • The water temperature stays a constant 68°F.
    • Jacob’s Well is the headwaters of Cypress Creek, which flows through Blue Hole Regional Park and feeds into the Blanco River.
    • More than 200 Native Indian groups populated Central Texas and were collectively known as the Coahuiltecans. Three of the most prominent Indian tribes that roamed this area are the Tonkawa, Jumano, and the Comanche.


Jacob’s Well Natural Area consists of five land surveys that all use the spring as a corner to tie the properties together. These surveys were conducted in 1847 by a prominent surveyor names Bartlett Sims. In the early 1850’s William C. Winters, a San Jacinto veteran and early settler of Wimberley, hiked up Cypress Creek searching for its source and found an overflowing spring. It is said that Mr. Winters exclaimed “like unto a well in Bible times.” Thus it was named ‘Jacob’s Well’. The property changed hands many times over the next 100 years and became a popular recreational destination. Jacob’s Well Natural Area remains a popular recreational destination today.

    • Bring plenty of water – Jacob’s Well does not currently have a public drinking fountain so be sure to bring enough for the whole family!
    • You are welcome to bring snacks or a picnic – Jacob’s Well Natural Area does not provide any food. Coolers are allowed but there is not much space for large coolers near the Well. Picnic tables are located throughout the park.
    • Due to the sensitive nature of the park, BBQ grills are not permitted.
    • Wear appropriate footwear – there will be a 15-minute hike to Jacob’s Well from the parking lot and the area surrounding the Well can be steep and slippery.
    • The walk down to Jacob’s Well is not stroller friendly and does involve several sets of stairs – you may want to consider leaving strollers in the car.
    • Know your limits – temperatures often reach 95 to 100°F over the summer months.
    • Accommodations can be provided to those who need assistance reaching the Well. Please let an employee know upon arrival if you require this extra assistance.
    • Swim at Your Own Risk – there is no lifeguard on duty.
    • Apply sunscreen 30 minutes prior to swimming so that it doesn’t come off immediately once you hop in.
    • Our parking lot is small so please consider carpooling if you are coming with a large group.
    • There is limited space in the swimming area – we recommend leaving large inflatable floats and pool toys at home.
    • The park gets very busy over the summer so we recommend making swimming reservations as soon as possible (at least 2 weeks ahead of time).
