Diving and Snorkeling in Komodo Island

Part of the Komodo Island travel guide — see every topic in All Komodo Island Guides.

Komodo National Park sits in the Sape Strait between the Flores and Indian Ocean water masses, and enormous volumes of water push through the gaps between the islands on every tide. That current is the reason the diving is world-class: it delivers nutrients, which feeds an extraordinary density of soft coral, which feeds everything else. It is also the reason Komodo is not a beginner destination. Sites here include drift dives, down-currents and washing-machine conditions that require experience and a guide who reads the tide tables properly.

The signature sites

Batu Bolong is a pinnacle in the middle of a channel, dropping from a metre below the surface to seventy, with the current splitting around it; you dive the sheltered side and it is one of the most densely covered reefs anywhere. Castle Rock and Crystal Rock in the north are current-swept seamounts where grey reef sharks and giant trevally hunt in the flow. Manta Point and Karang Makassar in the centre are the manta cleaning stations. Cannibal Rock and the Nusa Kode sites in the south are cold, nutrient-rich and macro-heavy — frogfish, pygmy seahorses, rare nudibranchs.

North and south are different oceans

This is the thing to understand when choosing a trip. The northern sites are warm — twenty-seven to twenty-nine degrees — with excellent visibility and big pelagic action. The southern sites draw cold upwelling from the Indian Ocean and can drop to twenty or twenty-two degrees with much lower visibility and far richer macro life. A five-millimetre wetsuit or a hooded vest is genuinely necessary in the south, and most day boats from Labuan Bajo only reach the north and centre. The south requires a liveaboard or a long day.

Snorkelling

You do not need to dive to see a lot here. Manta Point works for snorkellers — the mantas feed near the surface and the cleaning stations sit in five to ten metres — and it is one of the few places in the world where that is reliably true. Pink Beach, Taka Makassar, Siaba Besar for turtles and Kanawa island all snorkel well from a day boat. The caveat is the same as for diving: currents between the islands are serious, and you snorkel where the boat crew tells you to, when they tell you to, with the boat following.

Costs and logistics

A three-dive day trip from Labuan Bajo runs 1.8–2.8 million rupiah including equipment, lunch and park fees. Liveaboards are 3–8 million rupiah per person per night depending on the boat, with three to four dives a day, and are the only way to reach the southern and far northern sites properly. Most operators require an advanced certification and a logged minimum for the current sites, and a good one will ask. There is a hyperbaric chamber in Labuan Bajo, which is a meaningful safety consideration in a place with this much current.
