Makandawa Rainforest, near Kitulgala, Sri Lanka, is a lush 1,155-hectare tropical paradise within the Kelani Valley Forest Reserve. Home to towering dipterocarp trees, rare orchids, and medicinal plants, this biodiversity hotspot shelters purple-faced langurs, Sri Lankan leopards, and endemic birds like the Sri Lanka blue magpie. Bordered by the Kelani River, the forest offers adventure and eco-tourism opportunities, including white-water rafting, jungle trekking, birdwatching, and swimming in natural pools. The best time to visit is December to April, when guided tours provide deeper insights into its rich ecosystem.

Visitors can help preserve its beauty by practicing sustainable tourism. Easily accessible from Colombo, Makandawa Rainforest is a must-visit for those seeking an immersive nature experience in Sri Lanka’s wild heart.
