Sri Lanka’s waterways offer a quieter, more intimate perspective on the island’s landscapes and wildlife than any road can. Venture Ceylon arranges slow boat safaris through the Madu River mangrove ecosystem, kayaking through Kalpitiya lagoon’s flamingo channels, catamaran rides on the east coast, and sunset lagoon cruises through Negombo’s Dutch canal system. Water-level Sri Lanka is a different and very worthwhile island.
