Every evening, thousands of flying foxes stream out of Kalong Island’s mangroves at sunset — the signature closing scene of a Komodo sunset cruise and the classic first-night anchorage on a liveaboard. Kalong sits near Rinca Island, close to Labuan Bajo, so day boats and overnight charters both reach it easily.

Sunset cruises are one of the fastest-rising trip types in Komodo National Park, and the Kalong flying-fox exodus is the reason. In 2026 the scene became one of the most-shared Komodo moments on social video, and operators across Labuan Bajo added dedicated evening departures to meet demand. Here is how the exodus works, which trips include it, and how KomodoBoatCharter builds it into charters from a single evening to a full week on board.
What happens at Kalong Island at sunset?
Kalong is a small mangrove islet near Rinca Island — “kalong” is the Indonesian word for flying fox, the large fruit bats that roost in its mangroves by day. As the light drops, they lift off in waves and stream toward Flores to feed overnight, thousands of silhouettes crossing the sky above the anchored boats. The exodus happens every evening of the year; what changes is the sea state, the clouds and the color of the sky behind them.
Boats do not land on the islet. Captains anchor a short distance off the mangroves, guests watch from the deck — usually with tea, snacks or dinner served as the bats fly — and the show runs until dark. Our Kalong Island page covers the anchorage itself in more detail.
Where is Kalong and how do you get there?
Kalong sits on the Labuan Bajo side of the park, near Rinca. That location is why it works two ways: as the final stop of day one on a multi-day liveaboard route, and as a stand-alone evening cruise from town for travelers who are not sleeping aboard. On the classic 3D2N route, day one runs Kelor Island, a Rinca dragon trek, then the Kalong sunset before the boat anchors for the night — the full sequence is in our 3D2N Komodo itinerary guide.
A standard Komodo island day trip, by contrast, focuses on Padar, the dragon trek and the snorkel stops and returns to harbor around sunset — Kalong is the single best reason to add a night on the water.
Which trips include the Kalong sunset?
| Trip type | When you see Kalong | Nights aboard | Guide price |
|---|---|---|---|
| Evening sunset cruise from Labuan Bajo | Same evening, return after dark | 0 | Per-boat quote |
| 2D1N charter | Sunset of day 1, then night at anchor | 1 | Per-boat quote |
| 3D2N liveaboard | Close of day 1 (Kelor–Rinca–Kalong) | 2 | USD 300–450 per person shared |
| Private phinisi or yacht charter | Any evening you choose, repeatable | Flexible | From USD 800–1,500 per day, mid-range phinisi |
On a private charter the captain can position for the exodus more than once — many guests ask to repeat it on the final evening, since it costs nothing extra beyond the standard route.
When is the best time of year for a sunset cruise?
The bats fly year-round, so the real variable is the sailing. The dry season, roughly April–November, brings the most reliable conditions, with April–June and September–November offering the calmest seas in the park. December–March sailings still run — the harbor master reviews wind and wave conditions daily and boats sail in light-to-moderate rain — but evening trips are more weather-dependent, and captains keep plans flexible. July–August adds the most boats at the anchorage, so shoulder months give you a quieter deck and a clearer horizon.
How do you photograph the flying fox exodus?
Three practical notes from our crews. First, be anchored and settled before the light drops — the first waves come quickly, and boats arriving late motor through everyone else’s frame. Second, shoot silhouettes: expose for the sky, not the bats, and the wing shapes carry the image; video clips of the streaming colony are what performed so well on social feeds through 2026. Third, leave the drone in its case unless you have paperwork — drone use in Komodo National Park requires a paid special-activity permit, commonly quoted around IDR 2,000,000, and unauthorized flying risks confiscation and fines.
Is a dedicated sunset cruise worth it?
If your schedule allows a night on board, the liveaboard version wins: you get the exodus plus the anchored night and a sunrise start inside the park. If you are hotel-based in Labuan Bajo, the evening cruise is the most memorable few hours you can add to a land itinerary — and it pairs naturally with a celebration. Crews regularly arrange candlelit deck dinners and proposal setups timed to the bat flight; couples planning a bigger trip around it should read our Komodo honeymoon charter guide for routes built around exactly these evenings.
Either way, book the evening slot ahead in peak months — July, August and Indonesian public holidays fill first — and confirm dinner service when you reserve, since galley plans are set before departure.
What should you bring on an evening cruise?
Less than you think, but a few items matter. A light layer for after sunset — the breeze picks up once the sun is down and the boat is at anchor. Motion-sickness tablets if you are prone; the crossing to Kalong is short, but evening water can be livelier than a midday millpond. A power bank, since you will shoot far more video than planned. And a dry bag for phones and cameras on the tender ride. On overnight charters, meals are full board with water, tea and coffee as standard; alcohol is usually excluded from packages but sold on many boats, and some allow you to bring your own — confirm your vessel’s policy with the operator before departure so the sundowner plan matches the sunset.
