The Udawattekele Sanctuary is a historic forest reserve and is located behind the Temple of the Tooth. Consisting of 257 acres of lush vegetation, the forest was once a garden reserved just for the royals but has been opened to the public in the more recent times. The Udawattekele Sanctuary is home to many species of animals such as monkeys, wild boars, hare and porcupines to name a few. There are many tours that can show you around and the sanctuary is a great place for bird watching.
