The water is always 74 degrees and the mermaids have been here since 1947

Florida’s oldest underwater show is still running

An hour north of Tampa, a spring pushes more than 112 million gallons of water out of the ground every single day.

The Seminole called it Weeki Wachee, meaning “Little Spring” or “Winding River,” and the name still fits. The water holds at 74 degrees year-round and runs so clear you can see straight to the bottom.

Mermaids have been swimming in it since 1947. That tradition, and everything built around it, is what makes this place unlike anything else in Florida.

A Navy man and an air hose changed everything

Newton Perry trained Navy frogmen during World War II, and when the war ended, he took what he knew about underwater breathing and built a show around it.

On Oct. 13, 1947, he opened the first mermaid performance here, with swimmers breathing through air hoses hidden in the scenery.

His original theater sat six feet below the surface with 18 seats. In 1959, ABC bought the park and built the current theater, set 16 feet down with room for 400 people.

The state of Florida took it over on Nov. 1, 2008, and in 2020 it landed on the National Register of Historic Places.

Watch real mermaids breathe and dance underwater

The shows have run continuously for nearly 80 years, and they’re still the main reason most people make the drive.

Performers in colorful mermaid tails swim through choreographed routines, breathing from air hoses tucked into the underwater scenery.

The whole thing plays out behind glass windows that look directly into the spring.

The water is a natural aquamarine, and the visibility is sharp enough that you can track every move from your seat.

Shows run twice a day and last about 30 minutes. Doors open 30 minutes before showtime, and seating is first come, first served.

The deepest freshwater caves in America sit right below you

While the mermaids are swimming above, something much deeper runs beneath them. The cave system under this spring is the deepest known freshwater cave system in the United States.

In 2007, the Karst Underwater Research team got inside during a drought that lowered water levels enough to slip through the entrance, a narrow fissure about the size of a door.

They went down 407 feet and mapped roughly 6,700 feet of passages at an average depth of 265 feet. Under normal conditions, the spring’s current keeps divers out entirely.

Two water slides drop straight into the natural spring

Buccaneer Bay opened in 1982 and holds the distinction of being Florida’s only spring-fed water park. The Cannonball and Pirate’s Revenge both drop riders directly into the natural spring water, not a chlorinated pool.

A lazy river runs through the park, there’s a sandy white beach, and a wading area for children six and under stays calm and shallow.

The water slides and lazy river run seasonally, but the beach and swimming area stay open every day. One admission gets you into the water park, the mermaid show, and the wildlife presentations.

Paddle 2.8 miles down a river you can see through

The Weeki Wachee River runs 12 miles from the spring to the Gulf of Mexico.

Kayaks and paddleboards are available to rent inside the park, and the standard route covers about 2.8 miles downstream before a shuttle brings you back.

The water is easy enough for beginners, though the current runs strong near the springhead. What makes the paddle worth it is the clarity beneath you.

Fish, plants, and the sandy bottom stay visible the whole way. There’s no murk, no guessing. You can see everything.

Manatees gather here when the Gulf gets cold

From November through March, West Indian manatees move into the river to take advantage of the spring’s steady 74-degree water.

A deep spot called Hospital Hole draws them in particular.

You might also come across river otters, turtles, ospreys, herons, egrets, wood storks, and bald eagles working the shoreline.

Closer to the Gulf, dolphins show up in the lower stretches of the river.

Paddling this stretch during the cooler months means there’s a good chance something large and slow is passing beneath your boat.

Park rangers bring Florida’s wildlife up close

Set aside time for the ranger-led wildlife shows, which run about 30 minutes and feature live animals.

Rangers walk you through the species that live in and around the spring and river, and the format is more hands-on than a typical nature film.

It’s a good anchor point for kids, and it fills in a lot of context about the ecosystem you’ve been paddling through.

If you’ve been on the water already, the show connects the dots on what you saw.

The spring water hits you like a cool room on a hot day

You can swim in the spring at Buccaneer Bay, and the water pulls you in with visibility of dozens of feet in every direction.

At 74 degrees, it feels sharp when you first get in, especially if the air temperature is pushing into the 90s, which Florida does often.

Give it a minute and your body adjusts. Certified lifeguards cover the park throughout the day. The spring itself does the work of keeping the water clear and moving.

There’s no chemical smell, no cloudiness, just cold, clean water with the whole bottom visible beneath you.

Know this before you drive up

The park fills up fast, especially on weekends and during summer, so get there early. Glass and alcohol aren’t allowed inside, and coolers need to be 45 quarts or smaller.

One thing worth checking before you go: the Wilderness River Cruise has been paused during daytime hours since Dec. 2025 because of low water levels.

The official website has the current schedule.

Mermaid show seating fills on a first-come basis, and doors open 30 minutes before each performance, so don’t wander in at the last minute.

This is what Florida looked like before the theme parks

Weeki Wachee sits at the intersection of natural Florida and old-school Florida tourism, and there’s nowhere else in the state quite like it.

The spring’s turquoise water hasn’t changed. The mermaid show is still running. The river still flows 12 miles to the Gulf with otters and manatees in it.

What the park gives you is a version of Florida that existed before the highways widened and the crowds arrived, preserved inside a state park that’s open every day of the year.

Visit Weeki Wachee Springs State Park in Florida

You’ll find the park at 6131 Commercial Way in Spring Hill, about an hour north of Tampa and roughly two hours west of Orlando.

Admission runs $13 for adults, $8 for children ages 6 to 12, and children five and under get in free. That single ticket covers the mermaid shows, the wildlife presentations, and Buccaneer Bay.

The Wilderness River Cruise schedule varies right now, so check the official website before you go.
