Yala became a national park on 25 February 1938 and is divided into five zones for administrative convenience. It is known for elephants and leopards, as well as birdlife, and safaris run at first and last light, when the animals are most active.
Wildlife is wild, so no sighting can be promised. Parts of the park can close in the dry season, and a Ministry of Environment document describes it as conventional practice to close the park from 1 September to 15 October. We plan around the position for your dates.
