Komodo
Komodo National Park sits between Sumbawa and Flores in East Nusa Tenggara, Indonesia, and almost every trip starts from Labuan Bajo on Flores. Tidal exchange between the warm Flores Sea to the north and the cooler Savu Sea and Indian Ocean to the south drives the diving: water is pushed through narrow channels twice a day, and the currents that result are the main reason to come and the main reason to be careful. The park splits in two. Northern and central sites — Batu Bolong, Castle Rock, Crystal Rock, The Cauldron — are warm at 27-29C with 20-30m visibility in the dry season, and run reef sharks, giant trevally and dense schooling fish on current-swept pinnacles. Southern sites — Manta Alley, Cannibal Rock, Nusa Kode — sit in Indian Ocean upwelling: 22-26C, greener water, visibility often 10-20m, and correspondingly more plankton, more mantas and some of Indonesia's better macro. Reef mantas are in the park year-round, but a peer-reviewed photo-ID study of 1,085 individuals found they shift seasonally — peaking at the central cleaning stations from November to April and at Manta Alley in the south from May to October. Day boats from Labuan Bajo reach the central sites in 1-3 hours; the far south is liveaboard territory. This is advanced-leaning diving: down-currents and up-currents are a real and documented feature at Batu Bolong, Castle Rock and the Shotgun, not an exaggeration, and most operators want Advanced Open Water plus genuine drift experience for those sites. Park entry is fee-based and the rules have changed repeatedly — a daily visitor cap and compulsory advance booking came into force in April 2026.
What makes it special
- A documented inverse manta season inside one park: a photo-ID study of 1,085 reef mantas found peak abundance at the central cleaning stations November-April and at Manta Alley in the south May-October, as animals follow the monsoon and upwelling
- The Cauldron (Shotgun) — a tidal funnel between Gili Lawa Laut and Gili Lawa Darat where the channel accelerates enough to fire divers through mid-channel and out into blue water
- Northern warm-water pinnacles and southern 22-26C upwelling macro sites are dived on the same liveaboard itinerary, which is why boats carry both 3mm and 5-7mm suits
- The park's land half holds the only wild Komodo dragon population; the same entrance fee and ranger system covers both, and most liveaboards build in a dragon trek at Rinca or Komodo Island

Price is per person for a typical trip, excluding international flights ($ under $2,000 to $$$ over $4,000).
Komodo is one of the cheaper ways into serious current diving. Day trips from Labuan Bajo run roughly $145-210 for three dives, typically including park fees, gear and lunch — so a week of day diving plus a budget hotel lands well under $2,000. Liveaboards are around $1,500-3,500 per person for 7 nights on mid-range boats, with premium boats above $4,000; short 3-4 day Komodo itineraries from about $880. Flights to Labuan Bajo via Bali are extra. Park fees are additional unless bundled: budget roughly $20-30 per diver per day, but confirm with the operator, since sources disagree on the line items and many day-trip prices already include them.
Best time to dive
- Current
- Strong
- Water temp
- 24–30.5°C (coldest Jun, warmest Jan)
- Visibility
- 10–30m — Roughly 20-30m on northern pinnacles in the dry season (April-November); 15-25m central year-round; 10-20m and noticeably green in the south, where the upwelling that brings the plankton is the same thing that costs you the visibility. Wet-season plankton can drop inshore visibility to 10-15m.
- Getting there
- Moderate — Reachable but with some friction: 1 domestic flight, a 2h boat crossing.
- Experience
- Advanced-leaning. Batu Bolong, Castle Rock, Crystal Rock, Siaba Kecil and The Cauldron/Shotgun are advanced sites where operators expect Advanced Open Water plus real drift experience and reliable buoyancy; down-currents at pinnacles and walls are a documented risk and increase around full and new moon spring tides. Open Water divers are not shut out — Karang Makassar (Manta Point) at 5-16m, Siaba Besar and Tatawa Besar are dived by confident Open Water divers under guide supervision when conditions allow — but the sites Komodo is known for are not among them. Reef hooks and an SMB are standard.
Nearest airports
- LBJ — Komodo Airport (Labuan Bajo, Flores) (Domestic flights from Bali (Denpasar, roughly 1h20) or Jakarta; day boats and liveaboards depart from Labuan Bajo harbour)
- DPS — Ngurah Rai International Airport (Denpasar, Bali) (Main international arrival point for Komodo; connect onward to Labuan Bajo (LBJ))
Permit required
Since April 2026 all visits must be pre-booked through the official SiORA reservation platform — walk-in tickets are no longer sold — and the park is capped at 1,000 visitors per day, with sub-caps of 250 at Loh Liang (Komodo Island), 150 at Loh Buaya (Rinca) and 60 at Padar. Book at least 2-3 days ahead, or several months ahead for July-October. Most operators handle the booking for you.
Foreign visitors: entrance roughly IDR 150,000 per person on weekdays and IDR 250,000 on weekends and holidays, plus a diving activity fee (sources quote anywhere from IDR 25,000 to IDR 100,000 per diver per day) and smaller conservation and harbour fees. In practice operators quote about IDR 300,000-500,000 (roughly $20-30) per diver per day all-in. Sources disagree on the exact line items — confirm the total with your operator at booking, and check what your day trip or liveaboard price already includes.

Much less predictable than the reef manta and effectively a south Komodo animal — Manta Alley is the site where operators report them, in current-driven conditions, and they are rarely seen at the central cleaning stations. Coded occasional over the southeast monsoon (May-October) to follow the same upwelling that concentrates reef mantas in the south, and rare otherwise. This is an operator-reported pattern rather than a study-backed one; the PeerJ photo-ID work covers reef mantas (Mobula alfredi) only.

Napoleon wrasse are reported cruising past at Batu Bolong, Crystal Rock and German Flag through the year. Individually large and often solitary, so encounters are per-dive luck rather than seasonal — coded occasional, year-round, with no month weighting. Listed Endangered on the IUCN Red List, and Komodo's protected status is part of why they are still here.

Present in Komodo year-round, but where they are changes with the monsoon. A photo-ID study of 1,085 individuals (2013-2018) found peak abundance at the central cleaning stations — Karang Makassar and Mawan — from November to April on the northwest monsoon, with the lowest counts in August-September. At Manta Alley in the south the pattern inverts: peak May to October on southeast monsoon upwelling. Animals move between the two, roughly 35km apart. Park-wide the season is therefore close to flat, which is why no single peak is coded — pick the site to match the month, not the other way round. Densest aggregations reported at central stations are 10-20+ individuals in January-February. June-September at the central sites still produces individual mantas, just not the large aggregations.

Concentrated on the northern seamounts — Castle Rock and Crystal Rock, where operators report them patrolling daily — rather than spread through the park. Also reported at Langkoi Rock in the far south. Year-round; no seasonal pattern found in the sources reviewed. Best seen hooked in on the current-facing side, which is why this is an advanced-site animal.

Southern Komodo only in practice — Cannibal Rock and the Nusa Kode sites, on gorgonians. Resident year-round with no documented seasonality, but access is the real constraint: the south is liveaboard-only and southern itineraries are more common May-October. Cold water (22-26C) and a guide who knows the specific fans are both required.

Year-round and current-dependent rather than season-dependent — they hunt where the flow concentrates baitfish, so the northern pinnacles and Batu Bolong on a running tide are the reliable places.

Worth knowing before you book
- The currents are genuinely strong and not always predictable. Down-currents and up-currents at Batu Bolong, Castle Rock and the Shotgun are a documented hazard, worst within two to three hours either side of full and new moon spring tides. Operators cancel or move sites when conditions exceed the group — take that seriously rather than pushing for the famous site.
- Southern Komodo is cold and green. Upwelling drops Manta Alley, Cannibal Rock and Nusa Kode to 22-26C with visibility often 10-20m, and thermoclines can fall 5-8C without warning. A 5-7mm suit with a hood is the standard recommendation, and divers expecting warm tropical water are regularly caught out.
- Mantas are not guaranteed on any given day. Peak season means 10-20+ at a cleaning station on a good day, not every day, and June-September is the low period at the central sites — individuals still patrol, but the large aggregations are unlikely.
- Park fees and access rules have changed repeatedly and are still moving. A hike to IDR 3.75 million (about $250) was imposed on 1 August 2022, triggered a month-long operator strike in Labuan Bajo, was postponed, then cancelled in December 2022 — and April 2026 brought a 1,000-per-day cap and compulsory SiORA pre-booking. Current published fees vary between sources; treat any figure as provisional and confirm at booking.
- Labuan Bajo and the central sites are busy. Tourism at the central manta sites rose 34% between 2014 and 2017, and Karang Makassar takes the day-boat fleet from town daily; liveaboards get there first, day boats arrive into a crowd. The new visitor cap is a response to this, and it also means peak-season slots for July-October fill months ahead.

Note on the data: Manta seasonality is the one claim worth flagging as resolved rather than uncertain. Operator sites conflict badly — variously 'Dec-Feb in the south', 'Sept-Jan at Manta Alley', 'Jan-Mar at Manta Alley', 'the August upwelling is the biggest feeding event of the year' — and several of these contradict each other outright. The peer-reviewed PeerJ study (Germanov et al., 1,085 individuals photo-identified 2013-2018) is the strongest source available and finds the opposite of the common 'Dec-Feb in the south' claim: central sites peak November-April (northwest monsoon), Manta Alley peaks May-October (southeast monsoon upwelling), with animals moving between them. Region-level reef manta seasonality is therefore coded flat/resident rather than given a park-wide peak, because the park-wide total genuinely is roughly flat — the peak just moves between sites. The study itself notes limited December-February data at Manta Alley due to access difficulty, so the southern low season is under-sampled rather than confirmed absent. bestMonths follows the April-November dry season for all-round conditions and visibility, but manta-focused divers should weigh November-March for the central cleaning stations — the site's best-months field cannot express that split, so it is stated in the intro. Park fee figures are the weakest data here: no primary Indonesian government regulation was fetched, and operator sites disagree on both the entrance split (flat IDR 250,000/day vs IDR 150,000 weekday / IDR 250,000 weekend) and the diving surcharge (IDR 25,000 vs 100,000 vs 350,000). A range plus a confirm-at-booking caveat is used rather than a false-precision figure; this needs a primary-source check. The April 2026 visitor cap and SiORA requirement are well corroborated across news outlets (Jakarta Globe) and many operators, but were not verified against an official park page. Site coordinates are approximate. The 34% tourism increase figure is from the PeerJ study and covers 2014-2017 only. Water temperature: Two-temperature park: northern/central pinnacles run a warm 27-29C, but southern sites (Manta Alley, Cannibal Rock, Nusa Kode) sit in Indian Ocean upwelling and drop to 22-26C with thermoclines 5-8C colder, strongest in the Jun-Oct dry season. The satellite SST table (seatemperature.info) only captures the warmer surface average, so the dry-season low ends here are pulled down to reflect the documented southern upwelling from the region's operator sources rather than the table. Access: International arrival is via Bali (Denpasar), then one domestic flight to Labuan Bajo (LBJ); the harbour is ~10-15 min from the airport and day boats reach the central marquee sites in 1-3h, so headline diving is not liveaboard-only — only the far south is liveaboard territory. Independently verified 2026-07-20 (confidence high).
