The Muthurajawela Marshes are situated just south of Negombo and covers an area of approximately 6,000 hectares inclusive of the Negombo lagoon. The daily high tide brings in seawater from the ocean into the wetland. Continuous mixing of these two waters over thousands of years, has led to a brackish, integrated coastal ecosystem that is biologically diverse and teeming with life. A variety of mangroves and other types of flora including medicinal plants are found alongside numerous types of birds, butterflies and fish, some of which are endemic. Crocodiles, monitor lizards, and Sri Lanka’s largest snake, the Python, are also native.
