For 70 years the Miami Seaquarium was one of the city’s most visited family attractions — a 38-acre marine park on Virginia Key famous for dolphin shows, sea turtle rescue programs, and the legendary orca Lolita who lived there for over 50 years. After ongoing operational and animal-welfare concerns, the Miami Seaquarium permanently closed on October 12, 2025. This guide covers the legacy of the Seaquarium and — more importantly for current visitors — the best alternative marine and aquarium attractions in and around Miami for 2026.

Miami Seaquarium: Closure Status (Important Update)

The Miami Seaquarium permanently closed on October 12, 2025, after 70 years of operation. Tickets are no longer available. Animals have been transferred to qualifying sanctuaries, conservation facilities, and partner aquariums across North America. The 38-acre Virginia Key property is being evaluated by Miami-Dade County for future use, with discussions underway around marine education, conservation centers, or coastal restoration use.

If you were planning a visit, this guide outlines what visitors should plan for instead in 2026.

Miami Seaquarium: A Brief History

Founded in 1955, the Miami Seaquarium was one of the first marine theme parks in the United States. The 38-acre Virginia Key property hosted dolphin and sea lion shows, sea turtle exhibits, manatees, sharks, and tropical reef tanks. Iconic attractions included Flipper-style dolphin shows (the original “Flipper” TV series was filmed here), the Top Deck Dolphin Show, and the orca Lolita, who lived at the Seaquarium from 1970 until her death in 2023.

Over the decades the park drew millions of visitors but also faced increasing scrutiny over animal-welfare practices, particularly regarding marine mammal captivity. After multiple regulatory issues and lease disputes with Miami-Dade County, the property closed in October 2025.

Miami Seaquarium Alternatives: Marine Attractions in Miami

Phillip and Patricia Frost Museum of Science Aquarium

The best in-Miami alternative to Miami Seaquarium. The Frost Museum of Science houses a three-level aquarium featuring Florida-native species — sharks, rays, mahi-mahi, and a giant 500,000-gallon Gulf Stream tank. Combined with the planetarium and interactive science exhibits, it’s a full-day family destination. Located in Downtown Miami at Museum Park. See our Frost Science Museum guide.

Zoo Miami

While not strictly a marine attraction, Zoo Miami’s “Florida: Mission Everglades” exhibit features alligators, crocodiles, river otters, and the Lostman’s River Ride — providing a different angle on Florida wildlife. The largest zoo in Florida with 2,000+ animals. See our Zoo Miami guide.

Jungle Island

Interactive theme park on Watson Island with hands-on animal encounters — lemurs, sloths, kangaroos, parrots. Smaller scale and more interactive than the former Miami Seaquarium. See our Jungle Island guide.

Miami Seaquarium Alternatives: Wildlife & Marine Encounters

Crandon Park Marine & Education Center

On Key Biscayne (the next island over from Virginia Key). Free public marine education center with touch tanks, native Florida fish exhibits, and shoreline tours. Combine with Crandon Park Beach. Among the best free Miami Seaquarium alternatives for families.

Bill Baggs Cape Florida State Park

Marine education programs, manatee viewing (in season), and shoreline ecology programs. Park entrance fee $8 per car.

Biscayne National Park (Snorkeling Tours)

Boat-based snorkel tours through coral reefs and sea grass beds where you might encounter manatees, dolphins, sea turtles, and tropical reef fish in the wild. Among the most rewarding Miami Seaquarium alternatives for older kids and adults.

John Pennekamp Coral Reef State Park (Key Largo)

1 hour south of Miami in the Florida Keys. Glass-bottom boat tours, snorkeling tours, and shallow-reef exploration. The 9-foot-tall “Christ of the Abyss” underwater statue is a unique highlight. See our day trips from Miami guide.

Frost Museum of Science Aquarium — Best in-Miami option. Sharks, rays, and a 500,000-gallon Gulf Stream tank.
Florida Aquarium (Tampa) — 4 hours from Miami; one of the largest aquariums in the Southeast.
Georgia Aquarium (Atlanta) — Worth a regional consideration; among the largest aquariums in the U.S. Whale sharks and beluga whales.

Miami Seaquarium: What’s Next for Virginia Key?

Miami-Dade County continues to evaluate future use options for the former Miami Seaquarium property. Possibilities under discussion in 2026 include:

Marine education and conservation center — Continuing the educational mission without animal captivity.
Coastal habitat restoration — Restoring portions of the property to natural mangrove and shoreline habitat.
Public park and beach expansion — Integrating the land with adjacent Virginia Key Beach Park.
Mixed-use waterfront development — Restaurants, boutique hotel, marine recreation.

Updates are published periodically by Miami-Dade County and local news outlets. As of mid-2026, no permanent decision has been finalized.
