SCUBA DIVE | Sumbawa Adventure

SCUBA DIVE WEST SUMBAWA AND
MOYO ISLAND

Rugged coastlines, coral reefs, and healthy marine life in a region still off the radar for most divers. Sumbawa is still a yet-to-be-discovered destination which means healthy corals, both soft and hard, seasonal large pelagics, and everything in between.

We are located in Kertasari, 30 minute drive from Poto Tano harbour. Our daily scuba dives take place in the Kertasari and Poto Tano waters, with special excursions down south the West coast, or to the divers' paradise - Moyo and Satonda islands.

Suitable for: All levels, great beginner sites in the safety of islands with colourful reef life, leading up to advanced level sites with passing large animals and strong currents in the Sape straight.

Marine life

Manta rays near Kertasari during dry season and low winds

Whale Sharks frequent Moyo and Saleh Bay waters (We currently do not offer whale shark trips in Saleh Bay, focusing instead on marine experiences that meet our ethical and sustainability standards).

The waters around Kertasari and Poto Tano offer a good mix of diving conditions and marine life. Visibility is often clear, with some sites with drifts and currents, while others are calmer and easier to explore. Divers can expect a variety of soft and hard corals, anemones, and reef structures that attract reef sharks, stingrays, moray eels, octopus and hoardes of schooling fish. Smaller life is also common in certain sites, with nudibranchs and other macro species.

There is also a shallow reef area off the beach of the dive shop that can be reached as a shore dive or with a short boat ride when the tide is high, making it a simple entry level dive. The reef also hosts a coral nursery project, which is worth visiting for those interested in reef restoration efforts.

New dive sites are being explored right at this very moment, and one of the unique points of diving in Sumbawa is diving new, unexplored sites - if that's your jam.

Sustainable Diving Protocol

At our dive shop, sustainable diving isn’t a trend or marketing angle. It’s the foundation of how we operate, guide, and teach. Every dive follows seven non-negotiable protocols.

1. Perfect buoyancy

We train and guide with precision buoyancy control. No kneeling on reefs. No accidental fin damage. We hover weightless, controlled, intentional.

2. No-touch policy

Look, never touch. No coral, no turtles, no shells, no wreck souvenirs. The reef is not ours to handle, it’s ours to protect.

3. Calm, conscious movement

We dive slowly. We stay streamlined. We secure every hose and gauge. Our divers learn awareness of their fins, their body, and the fragile world around them.

4. Leave no trace

Nothing goes into the ocean. Nothing stays behind. If we see debris and it’s safe to remove, we bring it back with us.

5. Ethical photography

Marine life is never moved, chased, or stressed for a photo. The wellbeing of the ecosystem always comes before content.

6. Responsible Choices Above Water

We use reef-safe sunscreen, have zero single-use plastics, maintain our equipment carefully, and choose durability over disposability. Sustainability starts before we even enter the sea.

7. Active Ocean Guardianship

We don’t just avoid harm, we contribute. Cleanups, conservation awareness, and responsible partnerships are part of how we operate. We believe divers should leave a place better, not just untouched.

We are guests in this ecosystem.

And good guests move gently.

If you dive with us, you become part of that responsibility.
