If you are a nature lover and looking for adventure, a trip to Sri Lanka would not be completed without a boat safari or a boat trip along the Madu river which gives you a totally different perspective of wildlife and the wild natural surroundings from inside a boat. Make your way to the Madu River, where this tour begins at 9am. Board a boat into the mangrove marshes of the Madu River, traveling through shadowy caverns formed by the trees, and interspersed with bright open stretches of water. Madu Ganga has high ecological, biological and aesthetic significance, being home to 303 species of plants belonging to 95 families and to 248 species of vertebrate animals.
