Peterson Cay National Park is a small offshore cay located near Grand Bahama and offers visitors a chance to explore the island's marine environment.

The cay is identified as the smallest national park in The Bahamas and is accessible only by boat. Its surrounding waters provide opportunities for snorkeling, diving, marine-life viewing and photography.

Because Peterson Cay is not accessible by road, visitors typically experience it as part of a boat excursion. The clear Bahamian waters and surrounding reef areas make it especially appealing to snorkelers, divers, boaters and adventure travelers.
