Off Madagascar's northwest coast, separated from the mainland by roughly 8 km of the Mozambique Channel, Nosy Be is a volcanic island of about 320 km², roughly 30 km long and 19 km wide — one reason it's the country's most accessible resort island. Its highest point, Mont Lokobe, rises to 450 metres. Nicknamed the "Perfume Island," the name traces back to the island's ylang-ylang tradition — its flowers still scent a good part of the local economy through essential-oil production.
Nosy Be's earliest documented inhabitants belonged to the Antankarana and Zafinofotsy peoples, later dominated by the Sakalava. France colonised the island from 1840, founding the settlement that became known as Hell-Ville — today's Andoany, the main port and commercial town, home to roughly 109,465 people per the 2018 census. During the Russo-Japanese War, the island served as a supply station for Russia's Second Pacific Squadron. The economy, once built on sugar production, has shifted toward ylang-ylang cultivation and tourism: Nosy Be is now described as Madagascar's busiest tourist destination, and the only place in the country with large all-inclusive resorts. On Sunday afternoons, it's still common to watch traditional moraingy bouts, a popular fighting sport up and down the Malagasy coast.
The island's interior hides eleven volcanic crater lakes. In the southeast, the Lokobe reserve was established in 1927 as one of Madagascar's five original Strict Nature Reserves and is now managed as a national park (IUCN Category II). It shelters species including the black lemur, the Nosy Be mouse lemur, the Nosy Be sportive lemur, and the Nosy Be panther chameleon, several of them found only in this corner of the country. Visits are usually made by traditional dugout canoe from the coastal village of Ambatozavary.
Nosy Be also serves as a base for exploring a small archipelago of nearby islands — Nosy Komba, known for its semi-wild lemurs, Nosy Sakatia, Nosy Mitsio, and the more distant Nosy Iranja — most reachable on a day trip by catamaran or speedboat from the main island's west coast.
The west coast holds the island's most sought-after beaches and beach towns: Andilana in the north, Madirokely — the island's main nightlife hub — and Ambatoloaka further south. CoveTrip currently covers two of these beaches: the quiet Andilana Beach and the livelier Ambatoloaka Beach, with its bay-facing restaurants and bars, where Villa Les Orchidées is also based. Offshore, the Nosy Tanikely Marine Reserve is one of the region's most popular diving and snorkelling sites. Between September and December, peaking in October and November, juvenile whale sharks come close to Nosy Be's waters to feed on plankton; local dive operators run small-group outings to limit disturbance to the animals, and the island's offshore waters are also home to the little-studied Omura's whale. Worth noting: coral reefs around Nosy Be are under pressure from urbanisation, sugar-industry discharge, and unregulated tourism, according to Wikipedia — context worth keeping in mind rather than expecting untouched reef conditions everywhere.
Nosy Be has a tropical savanna climate, with a wet season from October to May and a dry season from June to September; daytime temperatures hover around 30°C year-round. The dry season is generally preferred for diving, though whale shark season runs into the wet season. Fascene Airport (NOS) receives flights from Ethiopian Airlines, Airlink, Air Austral, and, seasonally, Neos from Italy. Travellers arriving overland from the mainland can take a speedboat crossing between the port of Ankify and Hell-Ville, a journey of roughly 45 minutes. On the island itself, there are no traffic lights — traffic runs entirely on roundabouts.
The dry season, June to September, brings milder temperatures and clearer diving visibility; for swimming with whale sharks, the recommended window is October to December, already into the wet season, peaking in October–November.
By air, through Fascene Airport (NOS), served by Ethiopian Airlines, Airlink, Air Austral, and seasonally Neos from Italy; by sea, via a roughly 45-minute speedboat crossing between the mainland port of Ankify and Hell-Ville.
Local dive operators run boat trips between September and December (peaking October–November) out to the island's offshore feeding grounds, following small-group rules to avoid disturbing the animals.
