Overview
Muthurajawela is a large coastal marsh at the southern end of the Negombo lagoon, between Negombo and Colombo. It is one of the most important wetlands in Sri Lanka, with mangroves, reed beds and channels linked to the old Dutch canal. Its name is often translated as "supreme field of pearls".
What you see
A boat trip through the channels takes you past mangroves and reeds full of life. Birds include kingfishers, herons, egrets, cormorants and brahminy kites, with migrants from about September to April. Water monitors, crocodiles, monkeys and colourful dragonflies and butterflies are common. The marsh has a rich variety of plants, including several species of mangrove.
How a visit works
A visitor centre at the marsh has run guided boat trips, usually lasting about an hour and a half. Some operators in Negombo also include Muthurajawela on longer lagoon trips. Ask your hotel which option is running and the current price.
How long it takes
About two hours including travel from Negombo.
When to go
Early morning and late afternoon are best for birds and comfort. Migrants are present from about September to April.
Getting there
The marsh is about 20 to 30 minutes south of Negombo and roughly 30 to 45 minutes from Colombo, depending on traffic.
Practical tips
- Bring binoculars, a hat and insect repellent.
- Keep hands inside the boat; there are crocodiles.
- Do not feed the wildlife.
