Backpacking in International de l’Image Sous-Marine de Mayotte
👌 Worth visitingfestival ranked #4
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

Most screenings and exhibitions at the Festival International de l’Image Sous-Marine de Mayotte are held on land, so you can watch the reef on a big screen in the morning and swim over it the same afternoon. The festival takes place in Mamoudzou, on the main island of Mayotte, the lagoon-ringed French territory in the Comoros archipelago. Expect underwater film and photography, talks from divers and marine naturalists, and a crowd that mixes local dive-club members, photographers, teachers and curious travelers. The mood is relaxed and a little sticky, with ceiling fans turning, flip-flops on concrete and the smell of salt and sunscreen. Rooms fill with chatter in French and Shimaore. It is worth the trip if you care about reefs, turtles and whales, less so if you want a party. Start with a lagoon snorkel to get your eyes tuned, then settle into the first evening screening.

Ranked #4 festival in Mayotte
What makes it a must-see festival

The Festival International de l’Image Sous-Marine de Mayotte gives you a reason to look properly at what is under the water around the island. Mayotte sits inside one of the largest enclosed lagoons in the world, ringed by a double barrier reef, and the festival turns that setting into a program of films, photos and conversations. You hear from people who actually dive these passes, so your own snorkeling and dive days afterward make far more sense.

The other pull is the community. Because the event is small, you end up chatting with photographers, local guides and conservation volunteers in the same queue for the same screening. Those conversations are how backpackers learn which beaches have nesting turtles, which operators run careful whale encounters and where to get a boat without a … read more 👉

The other pull is the community. Because the event is small, you end up chatting with photographers, local guides and conservation volunteers in the same queue for the same screening. Those conversations are how backpackers learn which beaches have nesting turtles, which operators run careful whale encounters and where to get a boat without a tourist markup.

It also fits well into a longer Indian Ocean trip. Pair it with a few days in the Comoros or a stretch of beach time on Mayotte, and the festival becomes the anchor that gives the whole visit shape.

💡 HighlightsMust-see experiences and standout moments

  1. Underwater film screenings: The core of the festival. Documentaries and short films shot in the lagoon and open ocean play in a shared room, and the audience reacts out loud to a manta glide or a shark pass. Seeing the footage among locals who recognize the sites is the best context you can get.
  2. Photography exhibitions: Large prints of reef scenes, turtles, nudibranchs and whales line the venue. You can linger, compare how different photographers handle blue light and ask them directly how they got the shot.
  3. Talks with divers and marine scientists: Short presentations cover reef health, turtle monitoring and whale behavior in Mayotte’s waters. They are the quickest way to understand what you will see when you go in yourself.
  4. Lagoon snorkeling around Mamoudzou: Water time sits alongside the program.

  4. Lagoon snorkeling around Mamoudzou: Water time sits alongside the program. Warm, calm lagoon water, sandy shallows and coral heads close to shore mean you can test your own photo skills straight after a session.
  5. Turtle watching at N’Gouja: The beach in the south of the island is known for green turtles grazing on seagrass near the shore. Slip in quietly with a mask, keep your distance and you may share the water with one for as long as you like.
For a first visit, the underwater film screenings are the best place to start, because they set up everything else you will do in the water.

🌤️ When to go?When is the celebration of Festival International de l’Image Sous-Marine de Mayotte?

The Festival International de l’Image Sous-Marine de Mayotte is held in Mamoudzou, usually over several days in late spring or around the start of the dry season, with dates that shift each edition, so check the organizers’ calendar before booking flights.
  • Best day: Go on the opening evening for the first screenings and the full crowd of photographers and divers. Weekdays are quieter and easier for talking to exhibitors.
  • Weather: Expect warm, humid days around 27 to 30°C (81 to 86°F), with the odd short shower as the rains fade. Bring a light rain jacket, sun protection, a refillable bottle and sandals.
  • Booking: Reserve your bed 6 to 8 weeks ahead, since Mamoudzou has limited rooms and prices can rise 10 to 25% around the event. Flights into Dzaoudzi fill earlier.
  • Crowds and roads: Traffic jams

Book a hotel-area bed and your flight in the same sitting, because both sell out together.

🛏️ Where to stay?Choosing the right base

Mamoudzou is the smartest base for the festival, because the screenings, exhibitions and most of the dive crowd are within a short ride of each other.
The waterfront and town center around the main quay are the most practical choice. You can walk to cafés, ATMs, supermarkets and the barge terminal, and shared taxis (taxis collectifs) pass constantly. Evenings here feel lively without getting rough, though I would keep valuables out of sight and avoid dark side streets after late hours.

Evenings here feel lively without getting rough, though I would keep valuables out of sight and avoid dark side streets after late hours.
Kaweni, just north, is cheaper and more local, but it is busier and less relaxed at night, so it suits only confident travelers.
North of the center, Passamainty and the Tsoundzou side are residential and quieter, with private rooms and guesthouses at fair rates, but you will need rides after dark.
If you want beach time and a social mood among divers, look toward Petite-Terre, around Dzaoudzi and Pamandzi. The barge crossing takes about 15 minutes and runs frequently, but the last services leave earlier in the evening, so plan the return.
Solo travelers meet people most easily in Mamoudzou, where divers, photographers and volunteers gather around the event venues.

🍲 FoodLocal Flavors for Backpackers

Festival evenings in Mamoudzou run on street snacks and quick plates, with grills along the waterfront and small stalls near the venues.
Look for brochettes of grilled beef or chicken, samoussas and bananas fried or boiled, plus cassava and plantain served with fish. Island curries with coconut and ginger are the dishes to order for something truly Mahoran. A plate of poisson grillé with rice and a squeeze of lime is the one I would not skip.
For drinks, go for fresh fruit juices from passion fruit, tamarind or soursop, plus coconut water cracked on the spot. Coffee and mint tea are easy to find. Alcohol is limited in this largely Muslim island, so expect beer mainly in a few bars and restaurants, not at every stall.
Snacks cost about €1 to 3 each and a full plate runs €6 to 12. Cash is smoother … read more 👉

Queues move slowly but politely, so greet the cook first. Portions are generous, which makes sharing a plate with a new festival friend easy and sensible.

We 💚 feedbackSumming up the experience

The Festival International de l’Image Sous-Marine de Mayotte is best caught in the dry months, when the lagoon is calm and clear and whales pass offshore. Go to evening screenings, then spend the following mornings in the water while the sea is flat and the light is soft. Pack a reef-safe sunscreen and a rash guard, and book boat spots early.
