About this activity
Explore two of Negombo's most scenic waterways on a 6-hour guided boat safari through the Hamilton Canal and Maha Oya River. This immersive journey takes you deep into Sri Lanka's tropical countryside, where you'll encounter traditional fishing villages, lush bamboo forests, and abundant birdlife while tracing routes steeped in colonial and trade history.
Take a day trip from Negombo in the Hamilton canal and majestic Maha Oya to experience a tropical countryside boat trip to witness the riverine village life of fishermen, a Bamboo forest, and birds.
Follow the historic route of the spice traders along the Hamilton canal and then cruise upstream on this spectacular Maha Oya river to experience a tropical countryside boat trip and witness the riverine village life of fishermen, a Bamboo forest, and birds.
We can stop at a sandy beach for a swim in the freshwater.
The British Agent of Revenue and Commerce in 1802, Garvin Hamilton started a new canal to the east of the earlier cut canal by the Sinhalese king and the Dutch.
This canal was meant to link the Dutch canal by a series of parallel canals designed to drain the Muturajawela, what happened was the opposite as the high tide brought salinity not only from the Negambo lagoon but also from the Kelani River.
Thus the Hamilton Canal was born, named after Garvin Hamilton and stretching 14.5km from Colombo to Negombo.
