Set within the lush, bird-rich rainforest surroundings of Sri Lanka’s Wet Zone, this full-day experience offers a genuinely refreshing escape from the heat and pace of coastal or cultural tourism. Kitulgala is best known as the filming location for David Lean’s Bridge on the River Kwai, but its real appeal lies in the extraordinary biodiversity of the surrounding forest, the beauty of the Kelani River and the optional white-water adventure that makes this one of the most versatile day experiences available from Colombo.
