What Is Komodo National Park, and Where Exactly Is It?

Komodo National Park lies between Flores and Sumbawa in East Nusa Tenggara, Indonesia, covering roughly 1,817 square kilometres of islands and sea. It has been a UNESCO World Heritage Site since 1991. Its three main islands are Komodo, Rinca and Padar, and the only practical gateway is Labuan Bajo on the western tip of Flores.

Most people arrive knowing two facts: there are dragons, and there is a photogenic ridge. The park is considerably more interesting than that, and knowing its geography changes how you read an itinerary — particularly why boats move at night, why the currents matter, and why the same stretch of water is both a nursery for manta rays and a place captains treat with respect.

What is Komodo National Park, and where exactly is it?

Species figures vary between sources — you will see 1,000 to 1,100 reef fish and 250 to 260 corals cited — which is why the honest form is “more than 1,000” and “more than 250” rather than a false precision.

Why the geography matters to your trip

The park sits in a strait. Water moves between the Flores Sea to the north and the Indian Ocean to the south through a set of narrow channels, and it moves hard. That single fact explains almost everything about the place.

It explains the marine richness: strong tidal exchange pumps nutrients through the reefs, feeding a biomass of fish that divers travel a long way to see, and supporting manta rays at cleaning and feeding stations such as Karang Makassar and Manta Alley. It explains the temperature difference between north and south — the south sits in cold upwelling from the Indian Ocean, roughly 21 to 25 degrees at the peak of the June to September upwelling, against 26 to 29 in the north. And it explains why itineraries are built around tide windows rather than clock times, and why your captain will move a stop by ninety minutes without apology.

It also explains the terrain. These are dry islands — savannah, bare ridges, thorn scrub — not tropical rainforest. Padar’s famous three-bay panorama is a view of a landscape with almost no trees in it. Visitors who expect Bali greenery are surprised; visitors who expect somewhere closer to East Africa with a coral reef attached are closer to the mark.

The islands you will actually visit

Approximate sailing times between these points are set out in our Komodo sailing time table — useful because the park is bigger than a map suggests, and the distances are what force the overnight structure of every serious itinerary.

Diving: why it has the reputation it has

Komodo is a current destination. The famous sites — Batu Bolong, Castle Rock, Crystal Rock, Shotgun, Golden Passage — are pinnacles and channels where that tidal exchange concentrates fish, and where the same force demands real skill. Castle Rock and Shotgun are advanced sites with negative entries and reef hooks, not places to log your fifth dive. Batu Bolong runs 5 to 35 metres with permanent current and dense biomass.

Equally, the park is generous to beginners. Karang Makassar is a gentle drift in 8 to 18 metres where manta rays appear year-round and open-water divers are entirely at home. Siaba Besar is a sheltered bay used for check dives, with turtles and easy macro. Tatawa Besar is a classic soft-coral drift for intermediate divers. The range is unusually wide for one park.

Nobody publishes an authoritative site count. Specialist operators work with somewhere around eighteen core sites, rising to thirty or forty if you count variants and seasonal southern options — so “dozens” is the accurate word.

Seasons in one paragraph

April to June and September to November give the calmest sea and best all-round visibility. July and August are dry and clear but windy in the open straits, and they are the peak price and crowd months. December to March is the west monsoon: rougher, wetter, some vessels off for maintenance, more cancellations — and simultaneously the peak of manta activity, because plankton-rich water is exactly what draws them. The month-by-month detail is in our sea and crowd table.

Park area, UNESCO inscription year and species counts are widely published figures that vary slightly between sources; ranges are stated rather than false precision. Dive site counts are not officially published. Entrance figures follow PP No. 36/2024. See also: the Lombok to Komodo sailing route.
