Wilpattu National Park, the largest and oldest national park in Sri Lanka, spans an area of 1,317 square kilometers in the country's northwestern region.

The park is renowned for its unique Willus - natural lakes filled with rainwater that serve as vital water sources for wildlife.

Wilpattu is home to a thriving population of leopards, along with elephants, spotted deer, sloth bears, and an array of bird species, making it one of the most biodiverse ecosystems in Sri Lanka.
