Less visited than Yala but directly adjacent to it, Kumana National Park is defined by its extensive lagoon and wetland system, which makes it one of Sri Lanka’s most important bird habitats and supports significant elephant, crocodile, and water buffalo populations alongside the predator activity at its western boundary. The Kumana lagoon is one of the finest birdwatching sites in Asia, particularly during the April-to-July nesting season when the colony grows into the thousands.
