Kalong means fruit bat in Indonesian, and the island that carries the name is a mangrove-covered islet in the waters off Flores where a very large colony of flying foxes roosts by day. At dusk the bats lift off in streams and fly across the water toward the larger islands to feed on fruit. Watching the exodus from a boat as the sky turns orange is one of the most memorable things you can do in the area, and it needs no strenuous walking or early start. This sunset trip leaves Labuan Bajo in the afternoon, cruises out to the island and waits for the flight, then returns by dusk. It is a short, atmospheric outing that fits easily around a day of other activities, or into the end of a day when you have had enough of heat and effort.
The bats are wild and their timing depends on light and weather. Expect them to start leaving in the last half hour of daylight, with the peak flow as the sky darkens. Boats keep a respectful distance, and you should stay quiet and avoid bright lights, which can disturb the colony. A camera with good low-light performance helps, as does patience.
The boat ride itself is part of the attraction, passing small islands and fishing platforms in the golden light. Bring a layer, because the breeze on the water is cooler after sunset, and a repellent for mosquitoes near the mangroves. Check what is included, since some trips offer snacks or drinks on board and others do not.
Sunset trips can be canceled or shortened in rough weather, and the number of bats varies through the year. If you want to fit in more, combine this with a snorkeling stop or choose an open trip that includes a sunset finish.
