Being a rich country of natural bio diversity, Sri Lanka elaborates and proves it many times. Udawatte Kele located north of Kandy Lake is an eco-tourism site which expands over 103 hectares. The park was once a forbidden forest called Uda wasala watte (the garden above the royal palace) during the Kandyan kingdom. Visitors can tour the sanctuary every day from 6 am to 5 pm. Though the entire garden was declared as a forest reserve in 1856 and upgraded as a sanctuary in 1938.

This garden has an exclusive collection of avifauna. Other than that it is one of the beautiful bird sanctuaries in Sri Lanka.

Udawatte Kele is on a hill ridge stretching between the Temple of the Tooth and the Uplands- Aruppola suburbs. The highest point of the ridge is 635 meters above sea level and 115 meters above the nearby Kandy Lake.
