In Sarawak, the Mulu Challenge represents a once-in-a-lifetime opportunity to test your jet ski skills on a wild and virtually unexplored river that flows through virgin rainforest, deep into the heart of one of Asia’s last great expanses of wilderness.

Also known as Personal Water Craft (PWC), jet-skis are fast gaining popularity. Jet-ski tours are organised by various tour operators and can last up to 3 hours. They pass along the Menumbok River as well as circle around Labuan island. There is also the Annual Jet Ski.

Challenge and other privately organised races. Crafts may be rented by the hour from the Labuan Water Sports Centre.
