Sinharaja Forest Reserve
Ratnapura, Sabaragamuwa

Sinharaja is Sri Lanka's last major stretch of untouched primary rainforest, protected as a UNESCO World Heritage Site since 1988, and holds an extraordinary concentration of species found nowhere else on Earth — over 60% of its trees and a large share of its birds, amphibians, and insects are endemic. Guided walks along its network of trails move slowly, since the density of the canopy means most wildlife has to be listened for as much as spotted. It receives rain year-round, so mud and leeches are simply part of the experience rather than a sign of bad timing.
Best time to visit
January to March and August tend to have relatively drier stretches, though rain is possible any time of year.
Visitor tip
Use designated trails and a qualified local guide where required; rain can make trails slippery.
Local pick
Hire a local guide from the villages bordering the reserve rather than a general tour operator — they're trained specifically to spot the forest's endemic bird "wave" flocks that move together through the canopy.
