Maduru Oya National Park lies close to Mahiyanganaya and centers on the Maduru Oya reservoir, one of the major tanks built as part of Sri Lanka's Mahaweli development program. The park protects a rich mix of habitats — forest, grassland, and wetland — supporting healthy elephant populations along with deer, wild boar, and a wide variety of resident and migratory birds drawn to the reservoir. It's a rewarding, less-visited alternative for travelers who want a genuine wildlife safari experience without the crowds of Sri Lanka's more famous parks.
