Athol Island
An uninhabited island east of Paradise Island where the Bahamas' first marine protected area shelters pristine reefs and historic quarantine ruins.
Athol Island is an uninhabited two-mile stretch of land lying just three-quarters of a mile east of Paradise Island, forming part of the protected waters surrounding Nassau Harbour. In 1892, the waters west of Athol Island became the Sea Gardens, the very first marine protected area established in the Bahamas and one of the earliest in the Western Hemisphere.
Today the island draws snorkelers and boaters seeking crystal-clear waters teeming with tropical fish, sea turtles, and healthy coral formations. The ruins of the 1871 quarantine station — once used to isolate arriving ships during disease outbreaks — add a layer of history to this otherwise wild and undeveloped cay.
Sea Gardens Marine Sanctuary
The Sea Gardens earned their name from the extraordinary underwater landscape visible through the crystal-clear water — coral heads, sea fans, and waving gorgonians creating a living garden beneath the surface. This protected area prohibits fishing and collecting, allowing marine life to flourish just minutes from Nassau's busy cruise port.
Snorkeling tours typically anchor in the shallow protected waters where visibility exceeds 30 feet on calm days. Schools of sergeant majors, yellowtail snappers, and parrotfish swirl around the coral heads, while sea turtles graze on seagrass beds in the sandy channels between reef patches.
Quarantine Station History
Under the 1871 Quarantine Act, Athol Island became home to the Bahamas' first dedicated quarantine station. Ships arriving from ports with suspected yellow fever, cholera, or smallpox outbreaks were required to anchor offshore while passengers and crew underwent inspection and, if necessary, isolation.
The ruins of the quarantine buildings still stand on the island's western shore, weathered by more than a century of hurricanes and neglect. These stone foundations and remnant walls offer a glimpse into Nassau's maritime health history and the challenges of controlling disease in an era before modern medicine.
Visiting Athol Island
Athol Island is accessible only by boat. Tour operators from Nassau and Paradise Island offer half-day snorkeling excursions that typically include the Sea Gardens and a beach stop on Athol's western shore. Some tours combine Athol Island with visits to nearby Rose Island or Blue Lagoon Island.
The island has no facilities — no restrooms, fresh water, or shade structures. Visitors should bring sunscreen, drinking water, and snorkel gear. The Bahamas National Trust recommends protection for Athol Island and advocates for formal national park status to preserve both its marine and historical resources.
Getting there
Athol Island lies approximately three-quarters of a mile east of Paradise Island and is accessible only by boat. Several Nassau tour operators offer snorkeling excursions to the Sea Gardens that include beach time on Athol Island. Private boat charters and yacht crews can anchor in the protected waters west of the island. The crossing from Nassau or Paradise Island takes roughly 15 to 20 minutes depending on your departure point.
