Wildlife reports say there are more than 500 elephants in the park and they often roam in herds of up to 100. Buffalo, deer and sloth bears keep them company along with mongooses, bandicoots, foxes, water monitor lizards and crocodiles. A few leopards can be found in Udawalawe but they are rarer than Yala. A half-day tour in your own private jeep with driver and guide is the best way to see what the game park has to offer. The landscape is varied, consisting of marshes, scrublands, forests, hilly areas and open grasslands. Most nearby accommodation is mid-range but there are plenty of upmarket choices if you are prepared to drive an hour or two after your safari.

Other species found here include the Common Jezebel, Common Indian Crow, many species of ‘Yellows and Whites’ Common Mormon, and in the riverine forest areas Common Blue-bottle can also be seen. Udawalawe has become a haven for Butterflies in the resent past with the large number of ‘Lantan’ trees which have taken over the vegetation of the park. This being an invasive species to the park it is considered a pest; extensive work is being carried out by the park authorities husband this tree. It cannot be eaten by any of the herbivores in the park and competes with the endemic trees. However the flowers the Lantan are a big favourite of all the butterflies and the birds.
