Madu River: A Mangrove Wonderland
Where the Madu Ganga meets the sea near Balapitiya, between Bentota and Hikkaduwa, lies one of Sri Lanka's most rewarding day experiences: a boat safari through a sprawling wetland of mangrove forests, lagoons and dozens of tiny islands. A designated Ramsar wetland of international importance, the Madu River estuary teems with birds, monitor lizards and aquatic life — and hides cinnamon islands and a centuries-old island temple.
Top Sights & Things to See
1. The Mangrove Tunnels
The highlight of any trip: your boat slips into narrow, leafy tunnels formed by overhanging mangroves, with dappled light, birdsong and the occasional water monitor sliding past. It's serene, jungle-like and wonderfully cool.
2. Kothduwa Temple Island
A peaceful Buddhist temple sits on its own forested island in the river, reached by boat. Quiet and shaded, it's a lovely cultural stop amid the nature.
3. Cinnamon Island
On one of the islands, families demonstrate how Ceylon cinnamon is harvested and peeled by hand — a fragrant, hands-on look at the spice that shaped Sri Lanka's trading history.
4. Birds, Wildlife & the Fish Spa
The wetland is rich in kingfishers, herons, egrets, cormorants and eagles, plus monitor lizards and, occasionally, crocodiles. Many trips include a floating "fish foot spa," where little fish nibble your feet.
