This park stands on the fringe of the ancient Kaudulla Tank. It established a 6656-hectare elephant corridor between Somawathiya Chaitiya National Park and Minneriya National Park. Just 6km off the Habarana–Trincomalee road at Gal Oya junction, it is already a popular safari tour from Polonnaruwa and Habarana because of the good chance of getting up close and personal with elephants. In October there are up to 250 elephants in the park, including herds of juvenile males. There are also leopards, fishing cats, sambar deer, endangered rusty spotted cats and sloth bears. The best time to visit is from August to December.
A catamaran is available for boat rides on the tank.
