Sri Lanka can be divided into four regions: the central highlands, the southwest, the east, and the northern lowlands. The central highlands, with an average elevation of more than 5,000 feet, dominate the island’s relief. The terrain consists of high mountains and plateaus, narrow gorges, and deep river valleys. Near their center is the highest point on the island, Pidurutala Peak, which is 8,281 feet. The southwestern region is also mountainous and contains a continuation of the Rakwana mountain range of the central highlands. The eastern region is an undulating plain dotted with isolated hills.
