The Madu Ganga is a minor watercourse which originates near Uragasmanhandiya in the Galle District of Sri Lanka, before widening into the Madu Ganga Lake at Balapitiya. The river then flows for a further 4.4 km (2.7 mi) before draining into the Indian Ocean. In the Southern region of Sri Lanka lies the Galle district. Balapitiya is a little town in the district and would be quite unimportant; except for the location of a river. The Madu River is very rich in biodiversity. It passes through the wet zone of Sri Lanka opening up into the large Madu Lagoon on its way to the Indian Ocean. The Madu River Safari is a popular activity that has to be on the ‘to do’ list of any respectable Sri Lankan holiday goer. This unforgettable activity lasts for over two hours and gives a visitor a chance to travel the secretive passages through the mangrove forests and see the ecology.
