Kalong Island
Pulau Koaba, which is also known as Kalong Island (Fruit Bat Island), is a low-lying circular island measuring 500 metres across and appearing to comprise a core of taller trees surrounded by dense mangrove. At dusk, the sight of thousands of bats leaving their roost and heading for their feeding grounds is a magnificent spectacle.
The best time to get around the island is in the evening. Lots of bats start looking for foods. They leave their nest and fly in a group. No wonder, the sky is will be covered by these creatures. They are quite majestic. Another great time to witness these bats is in the morning. At this time, they come back to their nest. You can witness this moment from your boat. Since the island is covered by the mangroves, you aren’t able to explore it by foot. Not to mention there is no pier.
