Muthurajawela is a vital component of the local ecosystem. It is a marshland that sustains the local flora and fauna, in addition to being a natural mode of water regulation. According to historical sources, Muthurajawela was a rice farm, over which the Dutch had built a canal. This caused it to become a saline marshland over time, ending up being the stretch of saline haven that it is today. Boat rides can be arranged to tour the marshes. Ideally, these tours should take place either early in the morning or late evening, where the Sun can cast the whole place in a new light.
