from Key West Aquarium
The Key West Aquarium is Key West’s first attraction and was built by the WPA during the Depression. The facility took two years to complete and opened on February 18, 1935. It was the first aquarium in the world to use the open-air concept allowing for natural sunlight to illuminate the concrete marine displays. One of its original purposes was a marine repository for other aquariums from around the country.

In 1943 the US Government leased the Key West Aquarium to the Navy, Marine Corps, and Coast Guard who used it as a rifle range. In 1946 the Aquarium was returned to the city of Key West and restored to its former glory. In the 1960s the roof was added to the once opened air aquarium to cut down on algae in the exhibits. More modern methods of illuminating the tanks were slowly being developed and with it came the end of the open-air aquarium.

Today, the Key West Aquarium is home to sharks, turtles, stingrays, tropical and other various fish found in the beautiful waters of Key West. It is actively involved in the conservation of the delicate eco-system of the Florida Keys.

Aquarium Highlights:
  • Daily shark and turtle feedings and the Touch Tank offer guests a hands-on experience with the sea life of the surrounding waters.
  • The Aquarium features a wide variety of fish including grouper, moray eels, barracuda, tropical fish, tarpon, parrotfish, and much, much more.

Parking: Parking is available at Mallory Square or The Westin parking garage.

  • Shows & Feeding: 11AM, 1PM, 3PM & 4:30PM
  • Facial coverings are mandatory throughout the City of Key West.
