Komodo National Park sits where the Indian and Pacific Oceans meet. The water moving between them feeds everything you see: soft coral in the south, sharks and mantas on the northern pinnacles. It is a UNESCO World Heritage site.
Between dives, organised treks from Labuan Bajo take you to see Komodo dragons in their natural habitat.
When to dive Komodo
April to November (dry season) is the main window. The surface is calm, visibility in the north regularly reaches 25–35 m, and transfers between islands are comfortable.
December to March (rainy season) brings a rougher surface and lower visibility in the north. It is also a good window for mantas in the south, where cooler, plankton-rich water draws them in. The south dives differently then, with lower visibility, stronger thermoclines and 5 mm wetsuit weather, but Cannibal Rock and Manta Alley still deliver.
Mantas: the best months depend on the site
Our season data scores mantas highest in January to March and July to September. Our own guides put Manta Alley's peak at July to September, while other published calendars report it best from January to March and Karang Makassar from August to October. Sources disagree, so ask your operator which sites are working in your week.
Cold water in the south: pack a 5 mm suit
The north runs warm and clear. The south can drop sharply because of upwellings, particularly in the dry season. Pack a 5 mm wetsuit whenever you go: you will use it in the south, even in peak season.
Month by month
May to September is the peak window, and mantas score highest from January to March and July to September.
| Month | Conditions | Go for |
|---|---|---|
| January | Shoulder | Manta rays, the main draw. Wet season: rougher in the north and centre, and the south is the manta zone |
| February | Shoulder | Manta rays, the main draw |
| March | Shoulder | Manta rays, the main draw |
| April | Good | Manta rays (good chance) |
| May | Peak | Manta rays (good chance) |
| June | Peak | Manta rays (good chance) |
| July | Peak | Manta rays, the main draw, and reef sharks (good chance). Southern upwelling brings cold water: 5 mm suit |
| August | Peak | Manta rays, the main draw, and reef sharks (good chance). Highest crowds and prices; Castle Rock is at its best for sharks in July and August |
| September | Peak | Manta rays, the main draw, and reef sharks (good chance) |
| OctoberNow | Good | Manta rays and reef sharks (good chance). Karang Makassar mantas run August to October; a transition month with calmer winds |
| November | Good | Manta rays and reef sharks (good chance) |
| December | Shoulder | Manta rays (good chance). The wet season starts, and mantas build on the central reef |
From our Komodo season record, checked 9 October 2026, which draws on published season calendars and our own Komodo guides. Hammerheads, and reef sharks outside July to November, are scored as occasional sightings, so they are not listed.

Where to dive in Komodo
Choose your zone by what you want to see and how much current you can handle.
| Zone | How it dives | Sites |
|---|---|---|
| North | Clear water, strong current, reef slopes and pinnacles | Castle Rock, Crystal Rock, The Cauldron |
| Central | More accessible, for a wider range of levels | Batu Bolong, Manta Point (Karang Makassar), Tatawa Besar |
| South | Cooler water, richer in macro life | Manta Alley, Cannibal Rock |
Every northern site is Advanced. Tatawa Besar and Manta Point are the most forgiving.
| Site | Depth, level | The draw |
|---|---|---|
| Crystal Rock (north) | 10–30 m, Advanced | A submerged pinnacle that breaks the surface at low tide, known for visibility and schooling fish: grey reef sharks, giant trevally and seasonal tuna |
| Castle Rock (north) | 15–30 m, Advanced | A mound just east of Crystal Rock. Divers hook in to watch sharks, barracuda and jacks hunt in the strong current |
| The Cauldron, or Shotgun (north) | 10–25 m, Advanced | A fast drift through the narrow channel between Gili Lawa Laut and Gili Lawa Darat. The current shoots divers through, often past manta rays and reef sharks |
| Batu Bolong (central) | 5–30 m, Intermediate to Advanced | A small rock outcrop above a large underwater mountain. The current is strong, so divers stay on the lee side, over the colourful coral |
| Tatawa Besar (central) | 5–20 m, All levels | A drift along a coral reef, over fields of orange soft coral, with hawksbill turtles and reef sharks |
| Manta Point, Karang Makassar (central) | 5–15 m, All levels | A drift over a rubble bottom with coral bommies. The main manta site, with dozens of rays at the cleaning stations |
| Manta Alley (south) | 5–25 m, Intermediate | Rocky channels in the far south of the island. In the right season, 20–30 mantas feed and circle in the nutrient-rich water |
| Cannibal Rock (south) | 5–30 m, All levels | A sea mount in Loh Dasami Bay with dense macro life: sea apples, nudibranchs and frogfish |
Depths show the whole site. Dive within the limits of your certification.
Which level do you need for Komodo?
Komodo's drift dives deserve respect, but the park is not closed to newer divers. The central zone works for confident Open Water divers: Tatawa Besar is a manageable drift over soft coral, and Manta Point at Karang Makassar is open to most levels.
The northern pinnacles and passages such as The Cauldron need Advanced Open Water at minimum, and current-diving experience is strongly recommended. Castle Rock and Crystal Rock in strong current are advanced dives, not because of the depth but because the water moves fast and your response has to be instinctive.
If you are an Open Water diver, base yourself at a resort in Labuan Bajo with access to the central sites, and build confidence there first. With Advanced certification and 30+ dives but little current experience, tell your operator. Most run a good briefing and will match you to suitable sites.
Always carry a surface marker buoy (SMB) and know how to deploy it. Currents can carry you away from the boat, and being visible matters. The buoyancy lesson in our Academy covers the basics worth getting right before a current-heavy trip like this.
What you'll see in Komodo
Mantas are the stars. Manta Point at Karang Makassar and Manta Alley are both dedicated manta sites, and mantas gather at cleaning stations across the park through the year.
Fusiliers and snappers form a wall of fish at Batu Bolong, which in turn draws giant trevally and reef sharks. The northern pinnacles hold grey reef sharks, giant trevally and seasonal tuna.
The cooler south is the macro zone: flamboyant cuttlefish, rare nudibranchs, sea apples and frogfish. Also seen: pygmy seahorses, eagle rays, sea turtles, blue-ringed octopus and moray eels. If you shoot photos, our underwater photography tips cover the basics.
Komodo: liveaboard or resort?
A serious diver on a first Komodo trip should take a liveaboard. The three zones are spread across a large park, and a boat that sleeps on site gives you four dives a day without the daily transfers.
| Liveaboard | Resort in Labuan Bajo | |
|---|---|---|
| Zones | All three, in one trip | Mainly the central zone |
| Transfers | None; the boat parks on site overnight | A day-boat run to Crystal Rock and back, then Manta Alley the next day, eats a lot of time |
| Best for | Serious divers on a first trip | Returning divers, or travelling with non-divers |
The best Komodo liveaboards cover all three zones efficiently, and some extend into Raja Ampat for a combined two-week trip. A Labuan Bajo resort works well for central-zone diving and for non-divers.
Boats, costs and what to expect are in the Komodo liveaboard planning guide.
Still choosing between destinations? Raja Ampat vs Komodo compares the two. Raja Ampat is known for biodiversity, and the Banda Sea for its hammerhead migration.

Questions
Is Komodo suitable for beginner divers?
Only the central zone, and only for confident Open Water divers. Tatawa Besar is a manageable drift over soft coral, and Manta Point at Karang Makassar suits most levels. The northern pinnacles (Crystal Rock, Castle Rock, The Cauldron) are Advanced Open Water territory, with strong, fast current. If you are newly certified, start with a resort in Labuan Bajo focused on the central sites, get comfortable with drift diving, and work up from there.
What is the best time to dive Komodo?
April to November for calm seas and good visibility in the north. December to March brings a rougher surface but good manta encounters in the south, and Manta Alley and Cannibal Rock perform in any season. There is no bad time to dive Komodo: the choice is which zone and which animals you are prioritising.
Can you see manta rays at Komodo?
Yes. Karang Makassar (Manta Point) in the central zone and Manta Alley in the south are both dedicated manta sites. Karang Makassar suits all levels and works as a cleaning station year-round. Manta Alley can produce 20–30 rays on a dive in the right season. Sources disagree on the best months, and our season data scores January to March and July to September highest.
Liveaboard or resort for diving Komodo?
Liveaboard for the full park: north, central and south in one trip, with four dives a day and no long daily boat commutes. Resort if you want to mix diving with land-based exploration or you are travelling with non-divers. The central sites are good without a liveaboard.
What wetsuit do you need for Komodo?
A 5 mm suit, whatever the month. The north runs warm and clear, but upwellings can cool the south sharply, particularly in the dry season.
How deep is the diving in Komodo?
The average dive is 15–25 m, and the sites in this guide run from 5 m to 30 m. Open Water divers stay at or above 18 m (60 ft) and Advanced Open Water divers at or above 30 m (100 ft) (PADI). The depths in the site table show the whole site, not what you should dive. The northern pinnacles are Advanced dives because the current is fast, not because of the depth.
Which are the best dive sites in Komodo?
It depends on your level. In the north, Castle Rock, Crystal Rock and The Cauldron are Advanced dives in strong current, for sharks, giant trevally and fast drifts. In the centre, Tatawa Besar and Manta Point (Karang Makassar) suit all levels, and Batu Bolong suits Intermediate to Advanced divers. In the south, Manta Alley and Cannibal Rock are the mantas and macro sites. The site table above gives depths and levels.
Can you see sharks diving Komodo?
Yes. Grey reef sharks, giant trevally and seasonal tuna patrol the northern pinnacles, and Castle Rock is at its best for sharks in July and August. In our Komodo season record, checked 9 October 2026, reef sharks are a good chance from July to November. Hammerheads, and reef sharks outside July to November, are scored as occasional sightings.
Do you pay a park fee to dive Komodo?
Yes. The national park charges fees, and on a liveaboard the park fee is usually paid on board, on top of the day rate, and harbour fees depend on the operator. The Komodo liveaboard planning guide lists the amounts operators quoted, as of May 2026. Ask your operator for the current figures when you book.
