Sinharaja is designated as both a UNESCO World Heritage Site and a Biosphere Reserve. Its dense interior shelters endemic wildlife, including over 50% of Sri Lanka’s endemic bird species, making it one of Asia’s premier birdwatching destinations, as well as rare amphibians, reptiles, purple-faced langurs and leopards. A guided walk through Sinharaja forest, alive with the calls of endemic birds and the sounds of the jungle, is one of Sri Lanka’s most extraordinary natural experiences.
