The Udawatta Kele Sanctuary is an important bio-reserve on a hillside beside the Dalada Maligawa and spans 257 acres. Tourists can visit three Buddhist monasteries here while trekking through the forest’s dense and diverse vegetation. The toque macaques, barking deer, and slender loris are only some of the animals visitors can come across, while around 80 species of birds make this a birdwatcher’s paradise.
Wide varieties of orchids and several indigenous species of trees and shrubs grow in the forest.
