Sri Lanka is one of the best places in the world to watch Asian elephants in the wild. There are a number of National Parks where these gentle giants can be watched in their natural splendor. The Sri Lankan elephant (Elephas maximus maximus) is one of three recognized subspecies of the Asian elephant, and native to Sri Lanka. Since 1986, Elephas maximus has been listed as endangered by IUCN as the population has declined by at least 50% over the last three generations. It is estimated that Sri Lanka has the highest density of elephants in Asia. This is a seasonal event which takes place at Minneriya National Park during August and September. Other than Minneriya National Park, you can see large heard of elephants inside the Udawalawe National Park, Yala National Park, Lunugamvehera National Park, and Wilpattu National Park.
