Overview
Sinharaja Forest Reserve is the most biologically diverse patch of land in Sri Lanka — a 11,187-hectare lowland tropical rainforest in the southwestern corner of the Sabaragamuwa and Southern Provinces that has been continuously forested since the last ice age and is recognised by UNESCO as a World Heritage Site and a Biosphere Reserve of global significance. The forest is home to 64 endemic woody plant species, 95% of Sri Lanka’s endemic birds, and an extraordinary catalogue of endemic reptiles, amphibians, insects, and mammals found nowhere else on Earth. Walking the trails of Sinharaja — through the cathedral-like understorey of the forest, past streams of crystalline water, under the towering canopy of na, hora, and beraliya trees — is one of the most profound natural experiences available in South Asia. The forest’s endemism levels are so high that virtually every animal and plant encountered here is found in Sri Lanka alone.
