Nosy Hara National Park
Island Small marine national park famous for diving and islets
Nosy Hara off Madagascar’s northwest coast protects coral reefs, snorkelling sites and small limestone islets. Divers and naturalists visit for clear water, endemic reptiles and sea turtles.
Nosy Hara National Park is a protected island and surrounding marine area in Madagascar’s Diana Region, centred on the island of Nosy Hara off the northwest coast. The park conserves coastal forests, rocky island habitats and adjacent marine ecosystems.
Recreational uses are focused on low-density nature activities such as snorkeling, diving and small-boat visits to view coastal wildlife and marine biodiversity. The area supports coral reefs and coastal species typical of Madagascar’s northwest islands.
The park was established to protect both the island’s terrestrial habitats and nearby marine life, and it is managed as a conservation area with regulated visitor access. Nosy Hara lies off the northwest Malagasy coastline in Diana Region, accessible by boat from regional coastal towns.
- Habitat diversity: The park combines terrestrial and marine habitats with coral reef and coastal forest systems, making it of interest for snorkelling, diving and species observation.
