Kitulgala
Kitulgala is a small town in the west of Sri Lanka. It is in the wet zone rain forest, which gets two monsoons each year, and is one of the wettest places in the country. Nevertheless, it comes alive in the first three months of the year, especially in February, the driest month. The Academy Award-winning The Bridge on the River Kwai was filmed on the Kelani River near Kitulgala, although nothing remains now except the concrete foundations for the bridge (and, supposedly, the submerged train cars that plunged into the river in the climactic scene). Kitulgala is also a base for white-water rafting, which starts a few kilometres upstream.
