Vortex Spring
Location: Holmes County, Florida, United States
The property was purchased several decades ago by Doc Dockery, creator of the red and white diver-down flag. Dockery developed the site into a scuba diving destination that has hosted divers from around the world for many years.
Although ownership has since changed, the property continues to operate as a dedicated dive park.
Vortex Spring is known as the last confirmed location of diver Ben McDaniel in 2010..

Vortex Spring is a privately owned spring that has been operated as a scuba diving park for many decades. You can access it by driving north on highway 81 from Ponce de Leon, Florida. The billboard at Vortex Springs Lane is difficult to miss. There is an entry fee to enter the park, but you can stay the day and enjoy the swimming area. If you are scuba certified, bring your gear and certification card and spend the day exploring the spring basin.
Geological Context
Vortex Spring discharges from Florida’s karst limestone aquifer into a large spring basin before flowing downstream.
The cave system extends from the spring basin into underwater passage characterized by moderate depth and limited vertical profile compared to some North Florida cave systems.
The system has historically been accessible from within a managed dive park environment.
Structure & Layout
The cave entrance lies within the main basin and transitions from cavern into restricted cave passage.
The cave extends several thousand feet beyond the entrance and includes varying depth profiles and structural changes.
Due to prior incidents, access to portions of the cave is controlled.
Diving History
Vortex Spring was purchased several decades ago by Doc Dockery, creator of the red and white diver-down flag. Under his ownership, the property was developed into a dedicated scuba diving park and training facility.
Over the years, Vortex became a major training and recreational diving location in North Florida.
Although ownership has since changed, the spring continues to operate as a diving park.
In 1991, following multiple open water diver fatalities within the cave, a metal grate was installed approximately 300 feet inside the system. The installation was implemented as a safety measure to restrict unauthorized entry into the deeper cave passage. Following the placement of the grate, the site experienced a prolonged period without cave-related fatalities.
Ben McDaniel Disappearance
In 2010, diver Ben McDaniel was last seen at Vortex Spring before disappearing within the cave system. Extensive search efforts were conducted, including cave diver involvement. Despite these efforts, his body was never recovered. The event drew national attention and remains one of the most widely discussed incidents in Florida cave diving history.
Ben McDaniel’s disappearance later served as inspiration for a fictional thriller – Beyond the Grate.
Cultural & Regional Significance
Vortex Spring represents one of the most recognizable diving sites in the Florida Panhandle.
- Recreational accessibility
- Cave history
- Safety evolution
- Public attention
Its notable features make it distinct among Florida spring systems.
Cave Data
Diving Vortex Spring is quite easy. It’s a scuba diving park, after all. The spring basin is 25 feet at its deepest and offers a couple of metal caverns placed there by the Army Corps of Engineers many decades ago. They offer a man-made glimpse at what a cavern dive is like for those that are not trained to dive overhead environments. There is also an air box in the basin next to one of the artificial caverns. While the air in it is supposedly refreshed each morning, the oxygen content in it decreases as more divers stick their heads into it.
Visibility is generally good during the week and during the colder months. In the spring and summer on weekends, several dive shops and instructors from around the area and surrounding states conduct training dives and that tends to stir up the sediment enough to diminish the visibility.
The cave opening is at the bottom of a chimney located in one corner of the spring basin. If you’re lucky, you might see some freshwater eel swimming at the bottom of the chimney in and out of holes in the limestone. There’s a grim reaper sign just inside the overhead warning untrained divers to keep out. If you are trained, the cave continues to the right of the sign through a silty passage back to the Piano Room, a large room at 95 feet of depth.
The Piano Room contains an air box, like the one in the basin. There is also a grate at the far back right that continues deeper into the cave. There is a padlock on the grate to prevent untrained divers who decide to venture into the cave despite warnings from going farther. The key to the lock can be signed out from the dive shop by certified cave divers.
If you are a certified cave diver, the cave is low and silty. It can be done in backmount configuration. The restrictions listed on the map are all large enough except for the fourth restriction, which is the end of the divable cave, anyway. The cave gets to depths exceeding 150 feet, so bring Trimix.
Current Status
- Continues to operate as a commercial dive park.
- Grate remains in place, restricting access to deeper cave passage.
- Since installation of the grate in 1991, no fatalities associated with the cave system occurred until the disappearance of Ben McDaniel.
- One fatality occurred following Ben’s disappearance during search-related efforts.

Yes. The underwater cave begins at the bottom of the chimney located at the southeast corner of the basin. The first passage extends 300 feet back to the Piano Room. At that point, there are 2 branches of the cave. Both have restricted entry by iron grates. The Piano Room is far beyond the daylight zone and should only be visited by divers trained at the intro cave diver level and above.
The cave reaches a maximum depth of 160 feet beyond the grate. The maximum depth at the grate is 105 feet.
While recreational divers can enter the cave, they should not. Recreational divers should remain within their training limits and not go beyond the warning sign placed at the bottom of the chimney. The Vortex Spring cave is made up of small, silty passages in which the visibility is easily reduced substantially.
Vortex Spring Adventures is located is located north of Ponce de Leon, Florida off of highway 81. There is a billboard at the intersection of 81 and Vortex Spring Lane.
