The Sinharaja Forest Reserve, a UNESCO recognized World Heritage site is the best-known Rain Forest and an important biodiversity hotspot in the country. The vegetation at Sinharaja is that of a tropical wet evergreen forest with large trees believed to have unbelievable genetic potential.
This tropical rain forest draws thousands of visitors wanting to explore and experience this natural wonder that is rich in endemism, an inevitable treasure trove bursting with various species of flora and fauna.
