A private sailing charter from Lombok to Flores normally runs four days and three nights eastward across the Alas and Sape straits, calling at Sumbawa’s northern bays before entering the Komodo island group and finishing in Labuan Bajo. On a private boat the stops, timings and pace are yours to set, which is the main thing that separates the charter format from a shared cabin ticket on the same route.
The geography explains the itinerary. Lombok sits at the western end of the Lesser Sunda chain; Sumbawa lies immediately east across the Alas Strait; Komodo and Rinca sit between Sumbawa and Flores. A boat working eastward therefore has natural overnight anchorages roughly a day’s sailing apart, and the classic four-day route strings them together. This guide sets out what that route looks like day by day in 2027, what a private charter changes, and how to plan the crossing so you arrive in Labuan Bajo rested rather than relieved.
What does the standard four-day route look like?
Most eastbound charters leave from Lombok’s east coast rather than the tourist west, because starting closer to the Alas Strait removes several hours of sailing on day one. From there the sequence is broadly consistent across operators, with the exact anchorages chosen on the day according to wind and swell.
| Day | Typical zone | What it usually involves |
|---|---|---|
| Day 1 | East Lombok to northern Sumbawa | Crossing the Alas Strait, afternoon swim stop, first night at anchor |
| Day 2 | Moyo and Satonda area | Island walks, freshwater or crater-lake style stops, snorkelling on reef edges |
| Day 3 | Sangeang and western Komodo waters | Long passage past the volcanic island, arrival in the park’s outer anchorages |
| Day 4 | Komodo island group to Labuan Bajo | Ranger-led walk, viewpoint climb, reef snorkelling, afternoon arrival in port |
Boats going the same route in reverse — Flores to Lombok — run the identical anchorages backwards, and a private charter can be booked either direction. If you want that itinerary as a fixed package rather than a bespoke plan, the private charter lombok to flores page sets out the 4D3N structure and what the charter rate covers.
Why choose a private charter over a shared boat?
On a shared boat the schedule is fixed because twenty strangers have to be somewhere at the same time. On a private charter the boat waits if the light is good, skips a stop nobody enjoyed, and leaves an anchorage at dawn if you want the site to yourselves. That control is the product; the cabin quality is secondary.
- Departure and arrival times set around your flights rather than a fleet schedule.
- Stops added, dropped or extended by agreement with the skipper.
- Meal times and menu built around your group, including dietary needs.
- The whole deck, tender and snorkel gear available to your party only.
- Realistic option to reach quieter anchorages the group boats pass by.
The trade-off is cost per person: a private boat is priced as a whole vessel, so a couple pays far more per head than a group of eight filling the same cabins. Groups wanting maximum service on top of that control usually look at the vip sailing lombok tier, which adds crew ratio and concierge arrangements rather than simply a bigger boat.
When is the best window to sail east in 2027?
The dry season, roughly April to October, gives the most reliable crossings, because the straits between Lombok, Sumbawa and Komodo are where this route is most exposed to swell and current. August tends to bring stronger trade winds, which is fine on a well-found boat but noticeable on the longer passages. April to June and September to early October are the calmest practical windows.
From late December through February the picture changes. Squalls are more frequent, visibility for snorkelling can drop, and skippers will change the plan more often. Some operators pause the eastbound route entirely in the deepest wet-season weeks. If you are travelling then, treat the itinerary as indicative, build a buffer day before onward flights from Labuan Bajo, and confirm the operator’s weather and rescheduling policy in writing before paying.
How should you plan the logistics around the crossing?
The single most important logistical fact is that this is a one-way journey: you fly into Lombok and out of Labuan Bajo, or the reverse. Booking a return ticket to the same airport is the most common and most expensive planning mistake on this route.
- Book flights open-jaw, and leave at least one night in Labuan Bajo before any onward international connection.
- Confirm the departure harbour on Lombok; east coast starts often need a road transfer of a few hours from Senggigi or the airport.
- Pack in a soft bag — cabins have limited space for hard suitcases.
- Bring cash for park and conservation fees where these are not prepaid, and confirm current rates with the operator, since they are set by the authorities and change.
- Expect intermittent or absent mobile signal for large parts of days two and three.
What can you realistically expect on board?
Boats on this route range from traditional wooden phinisi with basic fan cabins to modern charter yachts with air conditioning, ensuite bathrooms and a full crew. The gap between those tiers is wider on a multi-night crossing than on a day trip, because you sleep, eat and shelter from the sun on the same vessel for three nights straight.
Ask specific questions before booking rather than accepting general descriptions. How many cabins share a bathroom? Is the air conditioning on all night or only while the generator runs? Is there shaded deck seating for everyone at once, or only sun loungers? Does the boat carry a tender for beach landings, and how many crew are on board? These answers shape the experience far more than the boat’s age or the photographs of the sunset deck.
Lombok to Flores charter questions, answered
How long is the sailing time between Lombok and Flores?
Four days and three nights is the standard, covering roughly the length of Sumbawa plus the Komodo island group. Faster crossings exist but they turn the trip into transport rather than a voyage, because the interesting anchorages get skipped. Slower six- to eight-day charters add southern Sumbawa bays or extra days inside the park, which suits groups who want snorkelling time rather than distance.
Can we change the itinerary once we are on board?
On a private charter, yes, within the limits of weather, fuel and daylight. Skippers will happily swap an anchorage, add a swim stop or start earlier for better light. What they will not do is add a destination that requires several extra hours of unplanned passage, because fuel and crew hours are calculated for the agreed route. Raise any wish-list stops before departure so they can be built in.
Do we need diving certification to enjoy the route?
No. The reef stops on this route are snorkelling sites reachable from the surface, and most charters carry masks, fins and buoyancy vests. Certified divers can usually arrange dives separately in Labuan Bajo or through a dive operator that joins the boat, but that is an add-on and must be arranged in advance rather than requested mid-trip.
Is the crossing rough?
The straits between islands can be lively, particularly in the afternoons and during the stronger trade wind months. Nights at anchor are generally calm because boats shelter behind headlands. Anyone prone to motion sickness should take medication before the first crossing rather than after, and choose a larger boat or a catamaran, which handles chop with less roll than a small single hull.
What happens if we run late for our flight from Labuan Bajo?
Skippers plan the final morning to reach port with a margin, but weather can compress that margin. The safe approach is never to book a same-day onward flight, especially an international one. Spend the last night in Labuan Bajo, or at minimum leave a long afternoon buffer, and tell the operator your flight time at booking so the route is planned backwards from it.
