This Udawaththa sanctuary is a royal park with about 257 acres which is considered as an essential biological reserve in Sri Lanka. This forest was used by the Brahmins in the past and was later used as a pleasure park by the upland kings. It is the belief of the villagers that the water comes to these royal ponds, which were used for bathing by the royal families, through tunnels connected to the Kandy lake. The reserve contains a variety of plant species, especially lianas, shrubs and small trees. In addition, many small and medium sized mammals, snakes and reptiles can be found in Sri Lanka. Also, very old monasteries and caves can be seen in this Udawattakele Forest Reserve.
