Sinharaja, meaning “Lion King,” spreads over 11,187 hectares of lowland tropical rainforest. As Sri Lanka’s only remaining primary rainforest, it has earned UNESCO World Heritage status for its rich biodiversity and ecological significance. Nearly 60% of the trees here are endemic, while countless birds, reptiles, insects and mammals find refuge under its dense canopy. 

One of Sinharaja’s marvels is the phenomenon of mixed species bird flocks, where dozens of bird species move together through the forest, a breathtaking experience for birdwatchers. Endemic highlights include the crimson backed flameback, Layard’s parakeet and Sri Lanka drongo. The forest also protects endangered mammals like the purple faced langur and giant squirrel. 

Trails through Sinharaja are often humid, shaded and alive with sound, frogs croak, cicadas hum and water trickles through rocky streams. Waterfalls such as Kudawa Falls add to its allure. 

Sinharaja is more than an ecological treasure, it’s also cultural. Local villagers gather medicinal plants and forest produce sustainably, reflecting centuries old traditions. Conservation efforts continue to safeguard this fragile ecosystem against encroachment. For visitors, Sinharaja is both humbling and inspiring, a reminder of how vital rainforests are to the planet’s balance and to our collective imagination.
