5-Day Komodo Liveaboard (5D4N): North & South in One Trip — When Season Allows

How our trips work: Labuan Bajo Diving is the dive-specialist team of our operating partner Komodo Luxury. Prices shown are typical ranges and are confirmed with a fixed quote before you book; conditions, levels and routes are always weather- and season-dependent.

A Komodo liveaboard 5 days 4 nights (5D4N) is the shortest itinerary that can realistically combine the north Komodo current sites — Castle Rock, Crystal Rock, Shotgun — with a proper swing through the south park’s Manta Alley or Horseshoe Bay, all in one trip. It logs roughly 12 to 14 dives depending on your departure day and conditions, and it works on a mid-range or premium phinisi without requiring the 6- or 7-day budget that a longer crossing demands. The catch, and it is a real one: the south leg only happens when the south is open — roughly October through April. In July and August, the route changes, and you should know that before you wire a deposit.

What the 5D4N Format Actually Covers

Five days on a phinisi in Komodo National Park gives you four nights at anchor, usually somewhere between Gili Lawa and the central island passes. A 5 day Komodo dive safari following the standard pattern runs like this: a warm-up day in central waters to run the check dive and settle gear, one day pushing south to the cold-water sites, a day at Pink Beach and Padar, then a two-day north finish through the current-heavy seamounts. That is the ideal sequence when conditions permit.

In practice, skippers read tides and swell forecasts daily. If the south is building a chop at 1.5 metres and the current report says the channel is confused, the south day gets dropped or substituted. A 5D4N trip does not guarantee south access any more than a 4D3N does — it just gives the skipper more flexibility to wait for a weather window. That is a meaningful difference.

On dive count: three dives per day is the Komodo standard, with a night dive slotted in on one or two evenings. Four days of diving at three dives each equals twelve, and a night dive on one evening takes you to thirteen. Some boats squeeze in a fourth morning dive before the final transit home, pushing the count to fourteen. Nitrox is widely available on mid-range and premium boats — often included, sometimes an add-on of around USD 15 per fill on mid-tier operators.

The Season Question — Read This Before Anything Else

Most liveaboard pages bury the season disclaimer in a footnote. I am going to put it here, second section, because it is the thing that most affects whether your specific trip delivers what you came for.

Komodo has two zones with opposite seasonal characters. The north and central park — Castle Rock, Crystal Rock, Shotgun, Batu Bolong, Manta Point — runs best roughly April through October. Water temperature sits at 27–29°C and visibility can hit 25–30 metres or better in July and August. This is when most liveaboards are running and when peak season bookings fill six to twelve months ahead under the park’s 1,000-visitor-per-day cap and SiORA allocation system.

The south park — Manta Alley at the tip of Komodo Island, Cannibal Rock and Horseshoe Bay down at Nusa Kode — works on the opposite calendar. These sites face the Indian Ocean. During the southeast monsoon (June through August), swell rolls in from the south, the channel gets rough, and the water turns murky with surface chop that makes zodiac transfers uncomfortable and underwater visibility variable. Most operators simply do not route south in July and August. The sites are not closed — the park has no seasonal regulatory closures — but the conditions frequently make them poor dives or impractical to reach safely.

The south window opens properly from around October into April. Water temperature drops to 20–25°C, sometimes lower with thermocline intrusions from Indian Ocean upwelling. Visibility is often 10–20 metres, occasionally better. Plankton blooms during this period are exactly what feeds manta rays at Manta Alley’s cleaning stations — the cold, nutrient-rich current is both the reason the site can be uncomfortable and the reason the marine life concentrates there.

The honest summary for a 5D4N trip:

• October through April: full north-and-south route is realistic; south day scheduled, weather permitting.
• May through September: north-heavy route; south may be attempted early or late in this window depending on the year; July–August, assume north-only.

We will tell you the expected route when you plan your trip with us — not after you have paid.

Day-by-Day Route Table

Below is the standard 5D4N routing for a trip with a south window available. The north-only variant for high season is noted at the bottom.

North-only variant (Jul–Aug or adverse south conditions): Day 2 moves to Manta Point (Karang Makassar) and Tatawa Besar; Day 3 adds Tatawa Kecil (advanced) or Wainilu for macro and a night dive. The itinerary is still excellent — it just lacks the south park’s cold-water macro intensity.

Thermocline Honesty: Pack for Both Zones

This is the detail that catches people on a mixed north-south trip. The north water in high season is warm — 27–29°C, and a 3mm shortie is genuinely comfortable. Then you transit south overnight and enter Manta Alley at 6 in the morning in 21°C water with a thermocline at 12 metres dropping you another two degrees. If you packed a 3mm, that is a cold, short dive.

For a 5D4N trip with a south leg, bring or rent a 5mm full suit minimum. A 7mm with a hood is not excessive for Cannibal Rock on a cold day in December or January. Most phinisis carry rental wetsuits; confirm thickness availability when you book, because the fleet varies. Your own suit guarantees the right fit — hoods and gloves especially tend to be limited on rental racks.

The north sites at 27–29°C feel like diving in warm soup after two days in the south. That contrast is, for many divers, the best part of the trip. Just be dressed for both.

Experience Level: Who This Trip Is For

The minimum for the full north-south 5D4N route is Advanced Open Water certification plus around 20 logged dives, and that minimum should be taken seriously rather than treated as a formality.

The check dive on Day 1 at Siaba Besar is not bureaucratic box-ticking. It is how the guide assesses whether your buoyancy is trim, whether your air consumption is in a reasonable range, and whether you are comfortable enough in open water to manage yourself at Castle Rock. Guides at Komodo’s current-exposed sites work ratios of roughly 1:4 to 1:6, and they cannot babysit someone who is finning hard to stay in position while simultaneously watching six other divers across a plateau in 2-knot flow.

If your logged dives are all from warm, calm, pool-adjacent conditions and you have not done a proper drift dive, the south sites in particular will be uncomfortable. Manta Alley uses negative-entry technique — you roll in and descend immediately into the current rather than waiting on the surface. That is straightforward if you have done it before, and disorienting if you have not.

Open Water divers are not excluded from the whole trip. Pink Beach, Siaba Besar, Mawan, Tatawa Besar, and Manta Point (Karang Makassar) are all manageable at OW level with solid buoyancy. The issue is that Castle Rock, Crystal Rock, Shotgun, Tatawa Kecil, and the south park sites are genuinely not appropriate for 10-dive OW divers, and a responsible operator will keep you on the boat or send you to a shallower alternate site during those dives. Some guests are completely happy with that arrangement; others find it frustrating. Better to have the conversation before you book.

What 12–14 Dives in 5 Days Looks Like

The dive rhythm on a phinisi is roughly: early morning dive at first light (best for sharks and mantas when the water is coldest and clearest), surface interval with breakfast, mid-morning dive, surface interval with lunch, afternoon dive, surface interval, sunset dive or night dive on designated evenings. Meals, boat briefings, and gear rinse cycles fill the gaps.

By the end of Day 4, experienced divers start to feel the accumulated nitrogen load and the fact that they have been in wetsuits for four days. This is normal. The guide will pace decompression-status dives accordingly, keeping safety stop discipline consistent and reminding you to fly-after-dive windows apply at the end of the trip. If your flight home departs the day you disembark in Labuan Bajo, check the recommended interval — 12 hours minimum after the last dive is the standard recreational guideline, 18–24 hours after multiple days of repetitive diving is more conservative and more sensible.

Per-Cabin Pricing: What to Expect

Observed market brackets for a 5D4N Komodo liveaboard per person, per cabin, are approximately:

Budget phinisi (shared cabin, fan or basic AC, shared bathroom)

USD 150–250 per night / roughly USD 750–1,250 for the full 5D4N. Gear often extra. Nitrox usually extra. Older vessel, smaller cabins, basic catering.

Mid-range phinisi (Komodo liveaboard private cabin, en-suite or shared two-cabin bathroom, AC)

USD 300–500 per night / roughly USD 1,500–2,500 for the full 5D4N. These are the most common boats on this route. A private cabin at this tier gives you a dedicated bunk or double bed, your own AC control, and enough storage to keep gear dry and sorted across five nights. Gear typically included; nitrox varies. Decent camera rinse facilities. Meals included.

Premium / semi-liveaboard (private en-suite, dedicated dive deck, camera room, better catering)

USD 500–750 per night / roughly USD 2,500–3,750 for the full 5D4N. Nitrox usually included. More experienced crew, better safety kit, higher guide-to-diver ratios.

Luxury phinisi and expedition yachts

USD 800–2,000+ per night. All-inclusive, private cabin with real beds, gourmet catering, dedicated dive guide per small group. Charter rates for the whole vessel on request — see our private charter page.

These are observed market ranges, not fixed prices. Actual rates depend on vessel, season, group size, and what is included in the package. Government and park fees of IDR 300,000–400,000 (approximately USD 18–27) per diver per day are typically quoted separately and are not included in per-cabin rates. On a 4-day diving trip that adds USD 72–108 per person. Confirm the fee structure before booking — some operators bundle them, most do not.

A private cabin versus a shared-cabin arrangement makes a significant difference on a 5-night trip. The ability to keep your gear sorted, sleep on your own schedule, and not negotiate bathroom time with a stranger when you are wet and tired at 6am is worth the price step for most people who can afford it. If budget is the constraint, shared-cabin budget boats run the same sites — the experience difference is in the accommodation and catering, not the diving.

Private Cabin and Whole-Boat Charter Upgrade Paths

If you are travelling as a group of four to eight divers and the itinerary matters — meaning you want to spend extra time at Castle Rock, skip the sites that do not interest your group, and set meal times around your dives rather than the boat’s shared schedule — a private charter makes more sense than buying multiple individual cabins on a shared departure.

Private phinisi charters allow you to customize the 5D4N route: add an extra north day, push further south toward Three Sisters or Yellow Wall, or drop the Padar land excursion in favour of another dive. You choose the dive guide, the catering style, and the pace. Rates span a wide range depending on vessel size and specification — contact our desk via WhatsApp for current charter quotes, as these are negotiated directly with operators and change with season and availability.

No one can pay to change what we publish here. If you use our free planning help and proceed with an operator through us, they may pay us a referral fee at no extra cost to you.

What You Will Not Find on This Page

Guaranteed manta sightings. Mantas are wild animals that move with food, current, and cleaning behaviour — their presence at any given site on any given day is not contractual. Manta Alley and Manta Point (Karang Makassar) are genuine manta hot-spots with year-round resident populations and aggregations that peak roughly from September through May, strongest December through February when plankton blooms are richest. But conditions vary, and no honest operator guarantees a sighting. The park-wide manta population is healthy and encounters are frequent — that is all anyone can responsibly say.

Similarly, Castle Rock will not always have sharks in the current. Some days the seamount is relatively quiet. The conditions that make the north sites spectacular — strong currents concentrating baitfish and the apex predators that follow them — are also the conditions that make them challenging dives. You are booking access to exceptional habitat, not a marine theme park.

Before You Book: A Practical Checklist

• Certification and log book: AOW card plus a log showing at least 20 dives, with drift dives listed if possible. Some operators require 50+ logged dives for Castle Rock and Shotgun — confirm before booking.
• Medical fitness: Liveaboard diving requires a completed medical declaration. Heart, lung, and equalisation issues are common exclusions. See a dive-medicine physician if you have any doubts.
• Wetsuit thickness: 5mm minimum for a mixed north-south route; 7mm with hood for the coldest south conditions (December–February).
• Dive computer: personal dive computer is expected, not optional. The guide cannot track your nitrogen load for you across 12–14 dives.
• DSMB: carry your own surface marker buoy and know how to deploy it. The north sites in particular require it — getting separated from the boat at Castle Rock is a real scenario that the local safety culture takes seriously.
• Dive insurance: DAN or equivalent. The nearest hyperbaric chamber is at Siloam Hospital Labuan Bajo (operators report it is the primary DCS treatment facility for the park). Bali is the higher-level backup. Evacuation time from remote sites can be 1–3 hours. Insurance is not optional.
• SiORA slot for land visits: if you want the Padar sunrise hike or a Komodo dragon trek at Loh Liang, confirm the operator handles SiORA time-slot allocation for land access. Popular slots fill ahead of the tourist season.
• Fly-after-dive buffer: plan your departure flight at minimum the day after you return to Labuan Bajo, ideally with a 12–18 hour buffer after your last dive.

Frequently Asked Questions

Is 5 days enough to see both the north and south of Komodo?

Yes, in the right season — roughly October through April. The standard 5D4N routing includes one full south day at Manta Alley and Horseshoe Bay, followed by two north days covering Castle Rock, Crystal Rock, and Shotgun. In July and August when the southeast monsoon makes the south sites rough and murky, the route shifts north-heavy and the south day is replaced with additional central and north dives. We will tell you which routing applies to your dates before you commit to a booking.

What is the water temperature in south Komodo and do I need a thick wetsuit?

South Komodo runs 20–25°C, sometimes cooler with thermocline intrusions from Indian Ocean upwelling — particularly in the December–February peak season at Manta Alley. A 5mm full wetsuit is the realistic minimum; 7mm with a hood is sensible for the coldest conditions. The north sites on the same trip run 27–29°C, so you may find yourself changing suit thickness between days. Most phinisis carry rental wetsuits but stock is limited on hood and glove sizes — bringing or renting your own suit guarantees the right thickness.

Do I need Advanced Open Water for a 5-day Komodo liveaboard?

AOW plus around 20 logged dives is the advised minimum for the full route. Open Water divers can join liveaboards and will dive comfortable sites like Siaba Besar, Tatawa Besar, Pink Beach, and Manta Point, but will be kept off Castle Rock, Crystal Rock, Shotgun, and the south park’s current sites. Some operators set the bar higher — 50+ logged dives for the north seamounts is common. The Day 1 check dive is how the guide calibrates which sites are appropriate for each diver in the group.

What does a 5D4N Komodo liveaboard cost per cabin?

Observed market ranges run from approximately USD 750–1,250 total per person on budget phinisis with basic shared-cabin arrangements, through USD 1,500–2,500 on mid-range private-cabin boats, up to USD 2,500–3,750 on premium vessels. Luxury options run higher. These figures are before park and government fees, which add roughly USD 72–108 per diver for four days of diving (approximately USD 18–27 per diver per day). Gear rental, nitrox, and land-visit ranger fees may be quoted separately depending on operator. Contact us for current operator rates and availability.

Can I book a private cabin rather than a shared departure?

Yes, most operators offer private-cabin bookings on shared-departure phinisis, and whole-boat private charters are available for groups who want full itinerary control. A private charter on a 5D4N route lets you customise dive sites, set your own pace, and avoid sharing the boat with strangers. Charter rates depend heavily on vessel size, specification, and season — reach out via our enquiry form or WhatsApp for current quotes tailored to your group size and dates.
