Things to Do in Nosy Be, Madagascar: Diving, Islands, and Wildlife

Nosy Be is Madagascar’s most developed tourist island — and deservedly so. A 320 km² volcanic island off the northwest coast, it offers world-class snorkeling, humpback whale encounters, and some of the most diverse marine life in the Indian Ocean.
It is also genuinely laid-back in a way that larger Indian Ocean resort islands are not. Infrastructure varies, the roads are rough, and power cuts happen — but that’s part of what makes it feel real.
When to Go to Nosy Be
- April–November — dry season. Best visibility for diving and snorkeling. Water temperature 26–29°C.
- July–September — humpback whale season. Hundreds of whales come to breed in the Nosy Be channel. This is the main reason to time your visit for mid-year.
- December–March — rainy season. Fewer visitors, lush green interior, lower prices — but some days are rained out and sea conditions can be rough.
Top Things to Do in Nosy Be
1. Snorkeling at Nosy Tanikely Marine Reserve
Nosy Tanikely is a protected islet 10 km south of Nosy Be’s main harbor (Hell-Ville). The marine reserve wraps around the island and contains some of the best-preserved coral in the region.
What you’ll see: green sea turtles (they are habituated and come close), white-tip reef sharks, rays, parrotfish, and dense reef fish. The snorkeling starts from the beach — no boat required once you’re there.
Boats leave from Hell-Ville harbor in the morning. Most tours include snorkel gear, a picnic, and time to climb to the island’s lighthouse.

2. Humpback Whale Watching (July–September)
The Mozambique Channel is a critical breeding ground for humpback whales. Between July and September, hundreds of whales congregate north of Nosy Be. Boats leave Hell-Ville harbor and reach the whale areas in 30–60 minutes.
What to expect: most tours guarantee sightings. Breaching, tail-slapping, and mother-calf pairs are all commonly seen. On calm days, boats drift with engines off while whales surface within meters. Bring seasickness tablets if you’re prone — the channel can be choppy in July–August.

3. Island Hopping: Nosy Komba + Nosy Iranja
The classic Nosy Be day trip visits two nearby islands:
- Nosy Komba — a small forested island home to semi-wild black lemurs. Walk the forest trails with a guide; the lemurs come close enough to climb on you (be respectful, let them come to you).
- Nosy Iranja — two islets connected by a white sand beach at low tide. The beach is stunning; snorkeling off the sandbar is excellent. Spinner dolphins are frequently spotted here.

4. Sunset Catamaran or Sailing
A sunset sailing tour around Nosy Be’s bays is one of the island’s most reliably enjoyable experiences. Most tours include drinks, snacks, and swimming stops. Dolphins frequently join alongside the boat at dusk.

Multiple PADI dive centers operate in Hell-Ville and Ambatoloaka. Open Water certification courses are available.
6. Lemur Encounter in the Interior
Nosy Be’s forested interior has resident populations of black lemurs. Several nature walks and guided treks explore the island’s volcanic hills.

7. Visit a Ylang-Ylang Plantation
Nosy Be is Madagascar’s perfume island — it’s the world’s largest producer of ylang-ylang, used in Chanel No. 5 and other perfumes. Several plantation tours explain the distillation process and production cycle. Tours typically include samples and an opportunity to buy essential oils.

Where to Stay in Nosy Be
Most accommodation clusters in three areas:
- Ambatoloaka — the island’s main tourist strip. Best for nightlife, restaurants, and dive centers. Noisy at night.
- Madirokely — quieter beach area north of Ambatoloaka. More mid-range hotels and family-friendly lodges.
- Andilana — the north tip of the island. Remote, upscale lodges, excellent beach. Requires a vehicle to reach town.
