Sinharaja is Sri Lanka’s most irreplaceable natural treasure – the island’s last significant area of primary lowland rainforest, a UNESCO World Heritage Site of breathtaking biodiversity. Over 60% of Sri Lanka’s endemic trees grow here, alongside an extraordinary concentration of endemic bird species that makes it one of Asia’s top birdwatching destinations. Guided walks through the forest move through a world of ancient trees, epiphytes, stream crossings, and the calls of species found nowhere else on earth. A genuinely rare and profoundly beautiful natural experience.
