Diego Suarez Bay and Northern Coast

For a trip combining Port Jasmine diving, Ramena and coastal excursions, late September through October is the strongest planning starting point. The identifiable dive operator says strong Varatraza winds, broadly mid-May to mid-September, often make its outside-bay dive sites inaccessible, even if an occasional sheltered bay trip remains possible. November can work, but the national cyclone season starts that month and extends to April. The exact best departure is always a forecast and boat decision, not a calendar promise. Leave a spare weather day and obtain direct written confirmation of the actual site and vessel.

Possibly, but plan for a smaller choice of sites and uncertain departures. The Port Jasmine operator says its exposed outside-bay outings become impossible or exceptional during approximately mid-May to mid-September. It sometimes considers dives inside Diego Bay when weather permits, with limited operation. That is not an assurance of year-round daily seats. If you travel in June, July or August, ask for the actual boat schedule, whether a protected bay site is suitable for your certification and what refund or alternative activity is offered when the wind prevents launch. Hiking may be a better backup.

Current status is unresolved in the reviewed evidence. Diego Diving Mario Matteo in Port Jasmine publicly claims Ramena scuba clubs have closed, but this is an interested party's claim, not independent proof. Meanwhile Hotel Lakana advertises scuba instruction in Ramena without naming a currently verifiable club or responsible instructor. Madascaph remains in an online directory, which could preserve old offerings. Do not book on the strength of a directory or either assertion. Request the operator's current name, qualifications, dive plan, equipment inspection, exact pickup and written confirmation for your date.

No regular bookable scuba liveaboard for this specific approved area was verified. The Port Jasmine operator describes sailing dive safaris but explicitly says they are suspended after damage to the sailing vessel, with no reopening date. Its other fleet descriptions concern small motorboats for day or half-day excursions. A separate overnight nature visit to Nosy Hara, or a pleasure boat arriving from elsewhere, must not be misrepresented as a scuba liveaboard. Organize a land-based stay with day diving, confirm the current operator schedule, and treat any new overnight scuba offer as unverified until the boat and permits are independently checked.

Start with a named boat operator at Ramena, where the regional tourism office says excursions commonly depart. Mer d Emeraude is reached by boat and features shallow water that changes noticeably with tides and wind. Ask for the embarkation point, licensed captain, passenger capacity, lifejackets, weather limits and included food and water. A site ticket is listed at Ar 10,000 for foreign visitors and Ar 5,000 for Malagasy nationals; check whether this is already in your excursion price. A boat-and-swim day is not proof that scuba, guided snorkeling or a safely supervised freediving session is included.

Diego Diving Mario Matteo lists supervised introductory scuba, age-appropriate training and guided snorkeling, and its gallery includes a shallow wreck used with children. These are evidence of advertised introductory services, not a safety guarantee or confirmation that a given class is available now. Beginners should request a calm, appropriate in-bay site with close instruction, a fit-to-dive check and clarification of medical documentation. The operator specifies different certificate requirements for various ages and course types. Families can separate activities: Ramena beach food, boat sightseeing and nature walks work without needing everyone to scuba dive.

There are two documented planning routes. The Port Jasmine club offers guided fin-and-mask marine nature excursions, and the regional tourism office describes shallow-water bathing stops on Mer d Emeraude boat outings from Ramena. The excursion page alone does not guarantee a certified snorkel guide or a fixed coral route. Farther west, Nosy Hara National Park explicitly lists snorkeling, under distinct park entry procedures. Ask each provider which precise area is legal and safe to enter, whether a flotation vest is available and how wind and tides affect plans. Do not swim into working boat channels or expect turtles on demand.

No dedicated operating freediving school, regular competition or managed depth line was reliably established for Diego Bay and Ramena as of 28 October 2026. The identifiable scuba club advertises snorkeling, but guided fin swimming is not evidence of formal breath-hold training or rescue staffing. A certified freediver could ask a qualified local specialist about a lawful, boat-protected site, but should not plan unsupported depth sessions. Require an actual instructor or trained safety diver, a one-up/one-down buddy method, surface signaling, oxygen/rescue procedures and a current weather assessment. If these cannot be verified, choose surface snorkeling instead.

Plan one condition-dependent Mer d Emeraude boat outing from Ramena, one day exploring the Three Bays coast and fishing-village food, and a guided nature day at Montagne des Francais or Montagne d Ambre National Park. The bays include Sakalava, Pigeons and Dunes, with wind sports and scenic walking. For an easier city stop, Cap Diego offers maritime-history views. Confirm entrance tickets and guides individually, leave a shore-based alternative in the schedule and never assume beach swimming is safe merely because the landscape looks calm in photos. This program is compatible with a scuba traveler doing separate morning dives.

No universal Diego Bay scuba marine-park permit or per-dive conservation tag could be verified from current primary sources. That absence is not proof that every reef is unrestricted. Ask your boat captain or local authority about site zoning, coastal community permission, harbor restrictions and any separate fees. The optional Nosy Hara National Park has distinct managed access and lists snorkeling, not a verified scuba visitor product. The regional office publishes a park entrance charge and guide fees, which should be reconfirmed with park management. Carry cash and comply with specific ranger instructions, wildlife rules and temporary closures.

The local airport is Antsiranana Arrachart (DIE/FMNA). Madagascar Airlines serves the destination, typically requiring a domestic planning connection if arriving from abroad; specific operating flights should be checked directly. The Port Jasmine dive operator advertises airport pickup when arranged in advance, while the tourism office places Ramena about 19 km from town by local road. Reserve the pickup with a named host or qualified driver. Ramena boats for Mer d Emeraude do not necessarily depart from the same place as the dive operator, so verify jetties before reserving lodging.

Seasonal wind and cyclone alerts can alter boat plans; currents and boat traffic must be assessed on the day. The operator describes oxygen and first-aid equipment, but the reviewed sources do not independently confirm its readiness or a working recompression chamber in Antsiranana. DAN recommends urgent local medical evaluation for suspected decompression illness, followed by expert referral and transport planning. Make sure your insurer covers diving and evacuation, and save Madagascar emergency number 117 for mobile calls plus DAN's international dive emergency line. CDC recommends malaria prevention review for destinations outside Antananarivo, including the north.

Expect separate expenses for domestic flights or vehicle travel, lodging, local transport, scuba boats and attraction tickets. A Ramena hotel's 2026 price page starts double rooms at Ar 90,000 per night and separately lists tourist and communal taxes. The Emerald Sea listing quotes an entrance ticket, excluding whatever your boat operator charges. The main dive operator's price page explicitly expired in May 2026, so a current scuba day price cannot responsibly be quoted from it. Obtain written itemized offers, check card acceptance and carry ariary for local fees. Do not assume transfers, rental equipment or park entry are bundled.
