South-west beach resort on the Bentota river, close to the mangrove islands of the Madu Ganga wetland
Bentota lies where the Bentota river meets the Indian Ocean, about 65 km south of Colombo, and its wide beach of golden sand has made it one of the south-west coast's classic resort areas. The calm river behind the beach is ideal for boat rides and water sports, and the coast nearby has turtle hatcheries and Bevis Bawa's Brief Garden.
A short drive further south, at Balapitiya, the Madu Ganga widens into a lake scattered with mangrove islands. A boat safari here glides through narrow mangrove channels to a sacred island temple and a small island where cinnamon is still peeled by hand. Together, beach and river make a relaxed short break or the first stop on a journey down the coast.
In the seventeenth century the Portuguese built a small fort at the mouth of the Bentota river, and the river marked the southern limit of their territory on the island. Bentota later developed as a beach resort, and Brief Garden, about 11 km inland, was created from 1929 by the landscape architect Bevis Bawa on a former rubber plantation.
The Madu Ganga is a short river whose estuary forms a wetland with the smaller Randombe Lake. It was designated a Ramsar wetland of international importance in 2003. Its islands are home to small communities who produce peeled cinnamon and cinnamon oil, and the sacred islet of Kothduwa holds a Buddhist temple reachable only by boat. Studies of the wetland have recorded around 300 plant species and nearly 250 vertebrate species.
Fishing, coir work and cinnamon cultivation have long supported families along this stretch of coast. On the Madu Ganga, a few island communities still live from cinnamon peeling and fishing, travelling by boat. Buddhist temples on the islands and the riverbanks remain active places of worship, so dress modestly when you step ashore.
Spend lazy mornings on Bentota beach and try water sports on the river. Take an early boat safari on the Madu Ganga, when birdlife is most active, to drift through mangrove channels, visit the Kothduwa temple island and watch cinnamon being peeled; look out for monitor lizards, water birds and, with luck, crocodiles.
Book boats with licensed operators and agree the route and price before you set off. Combine the trip with a visit to a turtle hatchery at Kosgoda, about 11 km south of Bentota, or a stroll through Brief Garden.
Bentota is on the south-west coast, where the sea is generally calmest and the weather driest from about December to April. During the south-west monsoon, roughly May to September, the sea is often rough and swimming can be unsafe, though river trips on the Madu Ganga can still run between showers.

Most of Bentota's hotels and guesthouses line the beach and the river, with restaurants serving seafood and rice and curry. Most coastal trains stop at Aluthgama, about 2.5 km north, while Bentota itself has a small halt on the coastal line. Madu Ganga boat trips typically start near the bridge on the Colombo-Galle road at Balapitiya, about 88 km from Colombo.
