Weeki Wachee Springs is a natural tourist attraction located in Weeki Wachee, Florida, where underwater performances by "mermaids", women wearing fish tails as well as other fanciful outfits, can be viewed in an aquarium-like setting in the spring of the Weeki Wachee River. A waterpark, Buccaneer Bay, and boat rides are also part of the attraction.
The spring was named "Weeki Wachee" by Seminole Indians, which means "Little Spring" or "Winding River" in their language. The attraction was created in 1947 by stunt swimmer and attraction promoter Newt Perry, who based the show on underwater air hose breathing techniques. First an 18-seat theater, then later a newer theater with a capacity of 50, were embedded in the lime rock of the spring with viewing windows below the surface of the water, to allow visitors to watch the mermaids perform in the spring. In 1982, Buccaneer Bay was opened with water slides, a lazy river, and a white sand beach for visitors to enjoy alongside the theater with the mermaid shows.
Guests to the park have included Elvis Presley, Don Knotts, Esther Williams, Arthur Godfrey, Kevin Smith, and Larry the Cable Guy. Hollywood has occasionally used the attraction and its mermaids in the filming of movies such as Mr. Peabody and the Mermaid (1948), Neptune's Daughter (1949), and many television shows. At one point, the attraction was owned by broadcast network ABC, and this led to an increase in publicity for the attraction. Currently, the park is owned by the Florida Department of Environmental Protection, and is a member of the Florida State Park System.
In 2005, English rock band Supergrass filmed their video for their song "Low C" at the Springs. They filmed a short documentary about the spring, as well as playing at a local bar and swimming with the mermaids.
On November 1, 2008, the state of Florida took over Weeki Wachee Springs as a state park.
From May 22 until August 30, 2007, the discharge level at Weeki Wachee spring dropped to a level that allowed for cave divers to gain effective entry into the cave system at the spring. The Karst Underwater Research team successfully executed exploration dives and the necessary in-water decompression to explore approximately 6,700 feet in multiple passages at an average depth of 265 Feet Fresh Water (ffw) with a maximum depth of 407 ffw. The 407 ffw depth makes the cave system under Weeki Wachee springs the deepest known freshwater cave system in the United States.
The 2017 documentary Mermaids featured the attraction as well as a number of former and serving mermaids.
