Wasgamuwa National Park is a dry zone park which is home to over 150 floral species, many of them endemic. The park also houses 23 species of mammals and over 140 species of birds. The number of reptile species is not low either. The park is especially popular for its elephant herds that you may see especially in the evenings. The Marsh elephant is a subspecies only seen near the Mahaveli River. You may also get to see two of the endemic monkey species found in Sri Lanka, or water buffalo, or even the rare sloth bear or golden palm civet. Some of the bird species that you may see are the endemic red-faced malkoha and the Sri Lankan junglefowl. You could also catch an elusive look at colorful peafowl, a painted stork, a black-headed ibis or even a Sri Lankan frogmouth. There are many reptiles you may see on the banks of water bodies, such as the Mugger Crocodile or water monitors. There are quite a few species of skinks, lizards, and snakes as well. There are around 50 species of butterflies in Wasgamuwa Park that may interest butterfly enthusiasts. Eight of these species are endemic.
