A wind-shaped northern bay for small-group dives, turquoise boat days and wild coast hikes.
Overview
Antsiranana, also called Diego Suarez, pairs Port Jasmine boat diving with Ramena fishing-village life, the boat-only Mer d Emeraude lagoon and breezy Three Bays landscapes. The identifiable local scuba operator, Diego Diving Mario Matteo, advertises training, guided reef outings and equipment from Port Jasmine. Its sailing dive safaris are explicitly suspended, so this is a land-based day-trip destination, not a confirmed liveaboard hub. Timing matters: the local Varatraza trade wind can prevent exposed boat dives from roughly mid-May to mid-September even when inland conditions are dry. Late September through October is a strong starting point for mixed dive and coast trips, with November increasingly exposed to the cyclone season. The status of Ramena scuba clubs is disputed between local businesses and cannot be treated as verified availability. Reserve with a named current provider, request its emergency plan, and keep no-dive days for beaches or inland walking.
Port Jasmine operator lists small motor vessels, local reef outings and entry-level instruction; confirm available spaces and boat seaworthiness directly. Operator equipment overview.

Ramena beach, Mer d Emeraude boat outings, Three Bays sightseeing and short coastal hikes create worthwhile plans without requiring everyone to scuba dive. Tourism office activity guide.
The Varatraza brings a real access trade-off: dry inland excursions can work while offshore diving is restricted from around mid-May to mid-September. Operator schedule advisory.
Nosy Hara is a managed marine park reached separately from Ampasindava, with guided nature visits and snorkeling described by the park. Park snorkeling is not permission for scuba diving. Park visitor information.
