Port
Port Havannah, located on the western coast of Efate, is one of Vanuatu's most significant sanctuaries for dugongs. The sheltered bay features extensive seagrass meadows that serve as the primary feeding grounds for these endangered marine mammals. Dugongs, often referred to as sea cows, can be observed here in small pods as they graze slowly along the seabed. The region served as a strategic US naval base during World War II, which shaped the underwater landscape with sunken relics that are now encrusted with coral growth. Scientific research in Port Havannah focuses on the migration patterns and reproductive behavior of dugongs to establish effective conservation zones. As dugongs have a very slow reproductive rate, protecting this specific habitat from boat traffic and pollution is critical for the species' survival in Melanesia. Collaboration between local villages and conservation groups has led to the establishment of 'tabu' zones, where fishing is restricted to support the marine ecology.

📋 Practical info
What is this place?
Port Havannah is a deep natural harbor whose seagrass meadows provide critical feeding grounds for rare dugongs. It serves as both a marine haven and a potential eco-tourism attraction for visitors interested in marine wildlife conservation.
Visiting
The port area itself is a working harbor, so typical public access is restricted for safety and security reasons. However, the surrounding coastline has opportunities to view the harbor entrance and the seagrass beds from a distance.
Where to view it
Good viewpoints can be found along the coastal road east of the port, where you can see the harbor basin and the lush hills behind it. Alternatively, boat tours from nearby Havannah Harbour village allow closer views of the seagrass meadows (depending on season and conditions).
Local products
Local fishermen occasionally catch fish and shellfish that thrive in the seagrass ecosystem, though dugong-related products are strictly prohibited. Visitors may encounter fresh seafood sold at small markets in Havannah Harbour, especially during the cooler months.
Active season
The seagrass is most productive during the warmer wet season from November to April, attracting higher numbers of dugongs. Boat tours and wildlife watching are typically best during calm mornings in this period, but dugongs can be seen year-round.
Nearby
Combine a visit to Port Havannah with the nearby Havannah Harbour Eco-Lodge or a trip to the Mele Cascades on Efate. The port is also a short drive from Port Vila, making it easy to include in a day tour of western Efate.
