Full description
The day begins early, with a van collecting you from Colombo or Kalutara for the run south along the coast road to Balapitiya. Allow around two and a half hours: this is the old road through fishing towns and coconut estates, moving at the pace of the villages it passes.
At Balapitiya the Madu Ganga widens into a shallow lagoon studded with small islands, and the boat cruise takes about two hours. The route leaves the open water for narrow channels roofed over by mangrove roots, passes prawn traps and cinnamon smallholdings, and calls at one of the island temples. Kingfishers, water monitors and troops of macaques along the banks are ordinary sightings rather than lucky ones, and the boatmen know where to slow down.
One of the islands is given over to cinnamon, which is worth understanding while you are standing in it. Sri Lanka grows true Ceylon cinnamon, a softer and more layered bark than the cassia sold as cinnamon in most of the world, and the peeling is still done by hand with a brass rod and a curved knife. Watching a peeler work a stem down to a quill explains why the real thing costs what it does.
The last stop is the Kosgoda Sea Turtle Conservation Project, where a guided hour covers the hatchery tanks, the nesting beach and the Turtle Guardian workshop. Five species come ashore on this stretch of coast, and the talk is honest about what a hatchery can and cannot fix: egg poaching, light pollution from the coast road and net entanglement are all part of the conversation.
Be clear-eyed about the length. This is a ten-hour day, with roughly five of them spent on the road in each direction combined. It suits travellers who want the mangroves and the hatchery without booking a night on the south coast, and it is a long day for very young children.
