Sinharaja is a UNESCO World Heritage Site and a Reserve of ecological importance and immense natural beauty. The forest shelters an incomprehensible density of endemic species: 95% of Sri Lanka’s endemic birds can be found here, along with hundreds of endemic plants, butterflies, reptiles, amphibians and mammals, many of which exist nowhere else on earth. Trekking through Sinharaja with a skilled naturalist is an immersive experience; the forest is alive with sound, movement and extraordinary detail at every level.
