Nosy Tanikely National Park

Nosy Tanikely National Park is a small protected island and surrounding marine reserve off the northwest coast of Madagascar in the Diana Region, noted for its coral reefs and marine biodiversity. It is part of the Nosy Be archipelago and is administered as a protected area by Madagascar authorities.

Shallow reefs and clear waters around the island make it a popular site for snorkeling and day-trip diving, with regular sightings of sea turtles, reef fish, and hard and soft corals. There is a short walking path across the island with ruins of a small lighthouse and a few sandy beaches suitable for landing small boats.

The area was designated and managed for marine protection and ecotourism to conserve reef habitats and resident species; local conservation groups and park authorities oversee visits and activities. The island’s uses have shifted from occasional local fishing and informal visitation to regulated tourism and reef protection.

Geographically the island lies off the northwest coast of Madagascar near Nosy Be in Diana Region, set in the Mozambique Channel. Access is by boat from Nosy Be and nearby ports; the surrounding seascape is low-lying and tropical.

• Snorkeling visibility: Best visibility is typically in the drier months when sea conditions are calmer, making snorkeling and diving easier.
• Protection and wildlife: The island is a protected marine reserve with coral reefs and frequent sightings of sea turtles and reef fish.

Nosy Tanikely is reached by boat from Nosy Be (Hell-Ville) or from the beaches/harbours around Nosy Be. Day-trip operators and local boatmen run speedboat and pirogue transfers from Hell-Ville and Andilana Beach; crossings typically take about 20-45 minutes depending on the boat and sea conditions.

When you land on the island you can walk from the small landing/beach area to the marine reserve, snorkelling spots and lighthouse in 5-15 minutes on foot.

• Take the earliest boat from Nosy Be and plan to snorkel around the island first thing; morning trips usually find calmer seas and fewer day‑trip crowds at the best dive spots.
• Choose a licensed operator that pays the marine park fee and follows the reserve rules-they'll know the best snorkel sites for turtles and coral and help you land at the correct beach access point.
• Walk the short coastal path to the lighthouse and viewpoints as soon as you arrive; many visitors skip this quick loop and miss the clear headland views and the chance to see reef life from the shore before boats get busy.
