Sinharaja Forest Reserve: Sri Lanka's Last Rainforest Treasure

About Sinharaja Forest
Sinharaja Forest Reserve, Sri Lanka's last viable area of primary tropical rainforest, is a UNESCO World Heritage Site and biodiversity hotspot. This pristine wilderness is home to over half of Sri Lanka's endemic species of mammals and butterflies, as well as many birds, reptiles, and amphibians. The dense canopy, rushing streams, and symphony of bird calls create an immersive experience for nature enthusiasts and researchers alike. Sinharaja offers guided jungle treks through ancient trails, where visitors can witness rare flora and fauna in their untouched natural habitat.
Deep within Sri Lanka's southwestern hills lies Sinharaja, a living laboratory of evolution and the island's most important biodiversity reserve. This ancient rainforest houses an incredible array of endemic species, including the Sri Lankan blue magpie, red-faced malkoha, and over 20 endemic bird species. Towering trees form a multi-layered canopy ecosystem, while crystal-clear streams cascade through moss-covered rocks. Expert naturalist guides lead visitors along well-marked trails, interpreting the complex relationships between plants, animals, and their environment. From medicinal plants used in traditional Ayurveda to rare orchids and pitcher plants, Sinharaja is a treasure trove of natural wonders that showcases the incredible biodiversity of Sri Lanka's wet zone.Location & Information
