Scenery in Southeast Asia picture - Clearwater Cave is Asia's longest cave, measuring some 107 km. It has a subterranean river, part of which is navigable by boat. There are two ways of reaching Clearwater. Firstly, you can trek along a 4 km nature trail which takes approximately one and half hours. Alternatively, you can travel by longboat along the Melinau River, usually stopping off at Wind Cave along the way. It normally takes about 15 minutes to reach Wind Cave by boat. When the water level is low the journey takes longer as the boatman often has to jump out of the boat and push.
