Bazaruto Archipelago: The Indian Ocean’s Last Dugong Stronghold

The dugong - a marine mammal related to the manatee, feeding on seagrass beds in shallow tropical water - exists in viable populations in very few places on Earth. The Bazaruto Archipelago off the coast of Mozambique holds one of the last significant East African populations, estimated at around 250-300 individuals in the protected seagrass meadows around the five main islands. This is the specific reason conservation organisations consider Bazaruto globally important; it is also the specific reason the archipelago has been a Marine National Park since 1971, with strict limitations on development and extraction that have protected the reef systems and the seagrass habitat.

For visitors, Bazaruto means extraordinary diving, the possibility of dugong encounters on boat excursions, white sand beaches that very few people reach, and a logistical commitment that keeps the crowds manageable. The gateway is Vilanculos on the Mozambican coast, a 90-minute flight from Johannesburg; from there, speedboats or light aircraft reach the islands in 30-120 minutes depending on destination.

The Islands

Bazaruto Island is the largest and most accessible, with the archipelago’s main lodges and the best-developed diving infrastructure. The coral reef quality around the island remains high relative to comparable Indian Ocean sites, a direct result of the park’s protection.

Benguerra Island is smaller and known for consistently good diving conditions. The Benguerra Lodge is one of the better coastal properties in southern Africa by most accounts.

Magaruque Island is quieter and sees fewer visitors. Dugong sightings in the seagrass shallows on the island’s lee side are more common here than at the more developed islands.

Santa Carolina Island (Paradise Island) was formerly a holiday resort under Portuguese colonial rule; the ruins of that development and a lighthouse remain. Rarely visited outside day trips.

Diving and Wildlife

The Bazaruto diving season runs April through October, when visibility is best. The outer reef has consistent populations of rays, turtle species, and reef fish; the more unusual sighting is the dugong encountered while snorkelling in the shallow seagrass lagoons. Seeing a dugong in the wild is not guaranteed on any single trip but is realistic over a 3-4 day stay. The park enforces strict approach distances for boats.

Getting There and Staying

Fly into Johannesburg, connect to Vilanculos on LAM Mozambique Airlines or Airlink. From Vilanculos, speedboat transfers to the islands run 30 minutes to 2 hours. Accommodation on the islands runs primarily in the upscale lodge model: Anantara Bazaruto Island Resort and Azura Benguerra Island are the established options, both all-inclusive or full-board. Budget accommodation does not exist on the islands themselves; Vilanculos town has guesthouses for visitors island-hopping on a tighter budget.

June through September is the best visiting window: dry season, calm seas, best diving visibility, and comfortable temperatures. November through March brings the cyclone season and higher temperatures; Mozambique can experience significant weather events in this period.
