Blue Lagoon Island

Dolphin encounters, sea lion swims, and a private island beach — Nassau's most family-friendly day trip.

Blue Lagoon Island, historically known as Salt Cay, is a privately owned island about three miles from Nassau, famous for its Dolphin Encounters marine facility. For over 30 years, a Bahamian family has operated responsible dolphin and sea lion programs here, offering visitors the chance to interact with Atlantic bottlenose dolphins in a natural seawater lagoon.

Beyond the marine encounters, Blue Lagoon Island features white-sand beaches, calm swimming areas, and full day-trip amenities. The island is a top choice for cruise passengers and families seeking a structured, well-organised excursion with both wildlife and beach time.

Dolphin & Sea Lion Encounters

Dolphin Encounters is the centrepiece of Blue Lagoon Island. Programs range from shallow-water meet-and-greets — where visitors stand on a platform and interact with dolphins at waist depth — to deep-water swims that include dorsal-fin tows and freestyle play. Sea lion encounters offer a similar progression, from introductory sessions to full swim programs.

The facility is accredited by the Alliance of Marine Mammal Parks & Aquariums, and the dolphins live in an ocean-fed lagoon rather than a concrete tank. Educational sessions explain dolphin behaviour, echolocation, and conservation before and after the swims.

Beaches & Island Amenities

Blue Lagoon Island's beaches are pristine and uncrowded, with calm, shallow water perfect for families. Hammocks, lounge chairs, and shaded cabanas dot the sand. A beach bar serves Bahamian cocktails and lunch, typically included in tour packages.

The island also offers kayaks, paddleboards, and volleyball courts. Freshwater showers, restrooms, and changing facilities make it easy to spend a full day. The atmosphere is family-friendly and well-organised, with staff guiding visitors through the day's activities.

Conservation & Education

Dolphin Encounters began as a rescue facility in 1989, and conservation remains central to its mission. Educational programs for students, educators, and families highlight the importance of marine ecosystems and responsible wildlife tourism.

Visitors leave with a deeper understanding of Atlantic bottlenose dolphins and the challenges facing marine life in the Bahamas. The facility's location on a private island — rather than in a resort aquarium — reinforces the connection between healthy oceans and healthy wildlife.

Getting there

Blue Lagoon Island is accessible only by boat through Dolphin Encounters, which operates departures from the Nassau waterfront near the British Colonial Hilton. Packages include round-trip boat transfers, beach access, lunch, and your chosen dolphin or sea lion program. Cruise passengers can book shore excursions through their cruise line or directly with Dolphin Encounters. The crossing takes about 25 minutes.
