Wasgamuwa National Park is one of the best places to observe Elephants. The best time to enjoy the sight of large herds is during November to May. In the rest of the year the elephants tend to migrate to nearby Minneriya and Kaudulla National Parks. Other wildlife includes Purple faced langur monkeys, wild boar, sambar and spotted deer, buffalo and rarely sighted leopards and sloth bears. Among the reptiles are water monitor, mugger crocodile, estuarine crocodile and python.
