"One of the last relatively untouched tropical rainforests and a UNESCO Biosphere Reserve, this remote reserve is a biodiversity hotspot bordered by the Koskulana Ganga and Gin Ganga rivers and reachable only on foot with an accredited guide. Hikes reveal endemic flora and fauna—including elusive Sri Lankan leopard, purple‑faced langur, toque macaque and rare butterflies—making it a hushed, species-rich destination for committed nature lovers. The requirement to be accompanied by a park ranger preserves both safety and the quiet, focused experience of the forest." - Tamara HinsonandErica Fong
