Sumbawa Liveaboard

Sumbawa liveaboard diving adds whale shark bagans, coral reefs and volcanic islands to the journey between Bali and Komodo. Rather than rushing across the map, the route makes room for Moyo, Teluk Saleh, Satonda and Sangeang, each with a different way into the water.

It is a quieter part of Indonesia, but not an empty one. A surface interval might lead to a waterfall, a crater lake or a volcanic shoreline before the next descent.

Where is Sumbawa?

Sumbawa sits in West Nusa Tenggara, east of Lombok and west of Flores, on the wider route toward Komodo. Mari’s Sumbawa experiences focus on the north-west cluster around Moyo Island, Teluk Saleh and Satonda, then continue east through Sangeang toward Komodo.

These are distinct areas, not one continuous reef system. That is why the passage works well on a liveaboard: the journey can join the island groups instead of turning every move into a return transfer.

Diving in Sumbawa

Sumbawa’s diving moves between calm and current-led settings. Teluk Saleh is sheltered and associated with bagan platforms, while exposed reefs around Moyo can bring drift conditions and more pelagic movement. Satonda and Sangeang add their own volcanic and macro-focused character.

Mari requires Open Water certification plus 30 logged dives for Sumbawa. That does not make every site identical, so conditions, experience and the group still guide the right site and dive plan.

In the Moyo, Teluk Saleh and Satonda cluster, water temperature is typically 27°C to 28°C (81°F to 82°F). A single March source from the separate Sape Strait reports colder 25°C to 26°C (77°F to 79°F) water, so this should not be presented as one uniform Sumbawa-wide temperature.

Top dive regions in Sumbawa

Sumbawa’s underwater map is more varied than its simple location between Bali and Komodo suggests.

Moyo Island

Moyo brings coral slopes, reef life and the Mata Jitu Waterfall excursion between dives. It is the gentler, green-island chapter of the crossing, with conditions that still vary across exposed reefs.

Teluk Saleh

Teluk Saleh is the whale shark chapter. Traditional bagan platforms can draw whale sharks to feed beneath them during the season, with encounters alternating between snorkeling and diving depending on the animals’ positioning and depth.

Satonda Island

Satonda combines soft-coral walls, hard-coral gardens and a manta cleaning station with a crater-lake hike and flying foxes at dusk. It brings diving and a volcanic land experience into the same day.

Sangeang

Sangeang is an active volcano off Sumbawa’s northeast coast. At Bubble Reef, volcanic vents send streams of bubbles through black sand, creating a distinctly different underwater scene for macro and wide-angle photography.

Beyond diving in Sumbawa

Snorkeling in Sumbawa

At Teluk Saleh, whale shark encounters can be experienced from the surface when conditions and animal positioning allow. Other snorkeling is selected site by site, rather than assumed across every dive stop.

Above water

Mata Jitu Waterfall on Moyo and Satonda’s hypersaline crater lake give the crossing a sense of place beyond the reef. At Satonda, flying foxes can leave the forest canopy at dusk in a single wave.

Best time to travel Sumbawa

Mari sails Sumbawa year-round, commonly as part of a route with Komodo. The right departure depends on the itinerary, weather and the balance of experiences you want.

Saleh Bay whale sharks have a source-backed season of April to November, but sightings are wildlife-dependent and no encounter should be promised. Moyo access is generally best from April to December, with January to March more exposed to strong westerly winds.

The current Mari route is planned around the season, weather, sea conditions and the group. Check the itinerary for the exact ports and the individual islands included on your departure.

How to get to Sumbawa

Mari’s finalized Sumbawa–Komodo crossings use Badas harbor near Sumbawa Besar as one end of the route and Labuan Bajo as the other. On the current 9-night westbound itinerary, guests disembark at Badas and transfer to Sumbawa Besar Airport (SWQ).

Best Sumbawa itineraries

Mari’s current Sumbawa–Komodo crossings run for nine or 11 nights between Badas, Sumbawa Besar and Labuan Bajo. The longer route creates more room for Moyo, Teluk Saleh, Satonda and Sangeang before the journey enters Komodo National Park.

Choose by duration, direction and the balance you want between Sumbawa’s whale shark and volcanic-island chapters and Komodo’s more current-led diving. The route cards and upcoming trips below carry the current details and availability.
