Discover the enchanting underwater world of the Florida Keys at the historic Key West Aquarium, a beloved landmark that’s been captivating visitors since 1935. Nestled in the vibrant heart of Mallory Square at 1 Whitehead Street, this pioneering open-air aquarium was the first of its kind in the United States, blending natural sunlight with stunning marine exhibits to showcase the rich biodiversity of Key West’s surrounding waters. Step into a realm where over 250 marine specimens come alive, from graceful sea turtles to sleek sharks, offering an immersive escape perfect for families, marine enthusiasts, and anyone seeking a unique beachside adventure.
Founded during the Great Depression to boost local tourism, the aquarium’s story is as compelling as its inhabitants. Constructed with seawater-mixed concrete under the vision of Dr. Robert O. Van Deusen, it opened its doors on February 17, 1935, as a showcase for the island’s native sea life. Today, it continues that legacy with interactive experiences that educate and inspire. Delve into the Touch Tank, where gentle hands can interact with queen conch, sea stars, urchins, and horseshoe crabs— a hands-on highlight that sparks wonder in visitors of all ages. Marvel at the ethereal Jellyfish Exhibit, home to mesmerizing cassiopea jellyfish drifting in illuminated tanks, or explore the Atlantic Shores and vibrant Coral Tank displays teeming with tropical fish, moray eels, barracuda, and grouper.
Meet unforgettable residents like Lola and Rocky, the world’s first sea turtles fitted with biomimetic prosthetic flippers, symbols of the aquarium’s commitment to rehabilitation and conservation. Daily presentations every 30 minutes bring the exhibits to life: witness thrilling shark and ray feedings featuring nurse, sandbar, blacknose, and lemon sharks; join guided sea turtle tours that reveal the plight and protection of these ancient mariners; or observe big game fish feedings that highlight the power of local waters. These engaging talks, led by passionate guides, weave in stories of marine research, coral restoration, and wildlife preservation efforts unique to the Florida Keys.
As the sun sets over Mallory Square—famous for its lively Sunset Celebration—the aquarium provides a serene counterpoint, inviting you to linger amid the gentle sway of sea cucumbers and the curious gaze of lobsters and stone crabs. Open daily from 9:00 AM to 6:00 PM, admission starts at around $29 for adults, with discounts for children, seniors, and groups. Whether you’re planning a beach day in Key West or seeking an educational detour from the sands, the Key West Aquarium delivers an intimate, enlightening encounter with the ocean’s hidden treasures. Embrace the call of the sea—your aquatic adventure awaits!
