Jacob’s Well, Texas’ Most Dangerous Diving Spot


Jacob's Well in Texas Hill Country is a perennial karstic spring located on the bed of Cypress Creek in Wimberley. The mouth of the well is four meters in diameter through which thousands of gallons of water surges up per minute feeding Cypress Creek that flows through Wimberley, sustaining Blue Hole and the Blanco River, recharging the Edwards Aquifer, and finally replenishing estuaries in the Gulf of Mexico.

The well was first discovered in the 1850s when a couple of early settlers followed Cypress Creek to its source. They described the crevice in the creek bed which was overflowing with an abundance of clear, cool water as "like unto a well in Bible times." Since then, the location has been a beloved swimming hole for generations, a gathering place for Native Americans and early settlers, and a rich habitat for aquatic species. It is also a popular diving spot for thrill seekers despite the fact that at least eight divers have lost their lives here over the years.

Jacob's Well is one of the longest underwater caves in Texas. From the opening in the creek bed, the cave descends vertically for about ten meters, then continues downward at an angle through a series of silted chambers separated by narrow restrictions, finally reaching a depth of forty meters.

Through the years, many have successfully explored the first and second chambers of the well. The first chamber is a straight drop to about 30 feet; then it angles down to 55 feet. Nourished by the rays of sunlight that penetrate the crystal water, this cavern area is bright and is home to algae and wildlife. The second chamber is a long funnel to 80 feet, where there is a restricted opening to the third chamber. Inside the second chamber is a false chimney, which appears to be a way out of the well but has trapped at least one diver. The third chamber is a small room with a floor of unstable gravel. Divers must inflate water wings to navigate this chamber successfully, trying not to stir up silt or dislodge the gravel.

The passage into the fourth chamber is very tight. The few who have seen the fourth chamber say it is "virgin cave" with fantastic limestone formations and no gravel. Covering the bottom is fine silt that can totally obscure vision when kicked up by one misstep.

Ironically, there was a time when it was impossible to descend into Jacob's Well. "There's a picture of me at 3 years old at Jacob's Well in the family album," recalls 79-year-old historian Dorothy Wimberley Kerbow. "My dad would throw me into the well. You couldn't sink down because the spring would just bubble you up with such force."

Kerbow recalls that she and her friends would often visit Jacob's Well in the 1950s, and it was impossible to go more than two feet below the surface due to the force of the spring.

In 1924, Jacob’s Well was measured to have a flow of one hundred and seventy gallons per second (six hundred and forty liters per second) discharging water six feet into the air. Over the years, the well’s flow had diminished allowing divers to reach the deepest chambers. The spring ceased flowing for the first time in recorded history in 2000, and again in 2008.

The first time the spring stopped flowing, the event was considered by many as symbolic of the region's increasing water shortage and quality problems. “It was a wake-up call for everyone,” recalls landowner David Baker. “We don't want it to turn into Jacob's Cave."

David Baker has given up his home to form the Jacob’s Well Natural Area to restore and protect this sensitive area for future generations.

  1. wonder how many beer cans rest on the bottom...

    1. well at lest 42 I know of

  2. Wonder how much wishing well money is at the bottom more like it

  3. Wish I could go and take a swim. Diving I might have to pass on. We really need to listen to our Mother Earth. She has important things to tell us. When will we ever learn.

  4. I'm 45 years old & live in Illinois, when I was 13years old I went swimming there... its still as beautiful as I remember!!

  5. At the bottom of this well, there dwells the spirits of nine (9) lost souls. I have personally read many of the numerous reports, generated by people who swam at the well over the years. ALL the swimmers reported themselves being touched, groped, fondled, glommed or just basically "felt up" in a general way. Some claim they were penetrated in a rude, yet sensitive manner. The somewhat respectful way that the tender flesh was manipulated suggests intelligence.

    1. Riiiiiight.

    2. Sure it wasn't surges of current ?

  6. This where kids go to get naked and have sex with each other. Even gay boys. You will probably get semen in your eyes. Also don't dive there, last time I dived there I died. It's dangerous.

    1. Need to grab his IP address and report him as a potential child molester and rapist.

    2. you're sick ! seriously! you're a danger for any kid

    3. Gotta love retard logic. Normal person: "Cat's live here." Retard: "OMG you're raping cats."

    4. Yea, someone said they saw you there taking it up the rear from some black guy.

    5. ^

  7. My boys.... Please be careful

  8. it seems a great place to dive!!

  9. This cave system is actively being dived by the Jacob's Well Exploration Project. They have been permitted through Hays County to conduct exploration and mapping in the cave. They have conducted several hundred cave dives through the system, which goes back almost a mile, without incident. You can read more about the project at their website:


    There were 8 known SCUBA fatalities in the cave and 4 free diving fatalities. There has not been a fatality in here since the early 80s and no cave trained diver has perished in this system.

  10. I dove Jacob's Well when I was a senior in High School. @ 90+ feet down, my dive partner got Vertigo in the 3rd chamber and I had to pull him out. The pressure at that depth was so strong it pushed the button on our light so we were in total darkness at the time. The ONLY way I couls ascertain Up from Down was to feel the Bubbles exiting my regulator behind my head.
    We were lucky to come out alive.

    1. So many years later and I have to call this lie what it is. Total Lie.
      90 feet isn't that deep and it wouldn't push the button on your light.
