Klias Wetland is a mangrove forest reserve and a destination quickly gaining popularity with tourists. Catch it before it becomes a tourist hotspot and experience the best of Kilas while it's still quiet and pristine. One of the major attractions is, of course, the chance to spot the rare Proboscis Monkeys. The tree-dwelling celebrities typically show up after sunset, so make sure you keep your eyes out for them as you sail along the river. You'll also enjoy a delicious dinner onboard and watch fireflies dance in the night sky.
