Key west Marine Life and Conservation Tours

Key West provides diverse travel experiences for visitors seeking history, marine wildlife, and outdoor activities. If you are curating your vacation itinerary around unique things to do in Key West, you’re on the path to connecting with the island’s ecosystem and historic heritage. This guide highlights key historical, ecological, and recreational tours available across the island to help you plan your visit to the Conch Republic.

Marine Conservation Tours

At the Key West Aquarium, we take pride in offering educational experiences that connect guests with the underwater world of the Florida Keys. Established in February 1935, our facility stands as one of the oldest standing attractions on the island. Built between 1933 and 1934 during the Great Depression, the aquarium was developed to provide local employment and stimulate the economy. As the first open-air aquarium in the continental United States, the original design relied on natural sunlight to illuminate the tanks. Founder Dr. Van Deusen envisioned a dual-purpose facility that would welcome tourists and marine scientists while serving as a biological clearinghouse for aquariums nationwide.

Throughout our history, the building has adapted to significant regional events. The 1935 Labor Day hurricane severed railroad connections to the mainland, impacting local tourism. In 1943, the United States government leased the building, converting it into an indoor rifle range for the Navy, Marine Corps, and Coast Guard. Following postwar restoration efforts and its return to the City of Key West in 1946, the aquarium resumed public operations. Historic Tours of America® acquired the property in the 1980s, completing extensive repairs, reinforcing tanks with fiberglass, and expanding exhibits. Celebrating over 90 years of continuous history, we remain dedicated to marine stewardship, rescue, and interactive public education. Exploring our historic exhibits remains one of the top unique things to do in Key West for visitors of all ages.

Sea Turtle Conservation Tour

Our Sea Turtle Conservation Tour offers an intimate look at vulnerable marine life and species protection. During this scheduled presentation, our marine guides introduce guests to our four resident sea turtles: Rocky, Lola, Spike, and Hector. These non-releasable turtles act as educational ambassadors for their species, representing common non-natural hazards found in wild habitats, such as vessel strikes, marine debris entanglement, and historical harvesting.

During the tour, guides detail individual rescue stories, ongoing medical care protocols, and nutritional maintenance programs. Guests learn actionable steps the public can take to protect sea turtle populations, such as keeping beaches clear of trash, reducing single-use plastics, and minimizing light pollution during nesting season. Participating in this presentation is one of the most educational and unique things to do in Key West for families looking to support ocean conservation.

Atlantic Shores Game Fish and Sharks Tour

Centered around a 50,000-gallon open-air exhibit, the Atlantic Shores tour educates guests on the essential ecological role of mangrove habitats along the Florida Keys coastline. Red mangrove trees within this exhibit act as natural water filters while offering shelter to juvenile marine life.
