Hidden beneath the canopy of Sri Lanka’s wet zone lowlands lies a world of astonishing biological richness: the ancient rainforests of Sinharaja and Kanneliya, both UNESCO-protected reserves and among the most biodiverse forest ecosystems in Asia. Sinharaja – meaning ‘Lion King’ – is Sri Lanka’s last viable area of primary tropical rainforest, home to an extraordinary concentration of endemic species found nowhere else on earth: 95% of its endemic birds, rare purple-faced langur monkeys, leopards, fishing cats, and hundreds of endemic plants, trees, and insects. A guided journey into these forests is not merely a nature walk; it is a passage into one of the planet’s most irreplaceable wild places, led by trackers with an intimate knowledge of every sound, track, and shadow.
