Sri Lanka's outdoor landscape is concentrated for its size and varied in its registers. The Horton Plains National Park and World's End is a walk through montane grassland above 2,000 metres to a cliff edge dropping 870 metres to the southern lowlands — on clear early mornings the view extends to the south coast 50 kilometres away. Yala National Park in the southeast has the highest density of leopard per square kilometre of any national park in the world, accessible on jeep safari in scrub forest and grassland that makes sightings more reliable than anywhere else in South Asia. The Sinharaja Forest Reserve, a UNESCO World Heritage site of lowland rainforest, is a guided trail system for endemic bird watching of extraordinary quality — the Sinharaja endemic bird wave (15 species moving together through the forest) is a spectacle that draws ornithologists from across Asia. Then the hidden gems start showing up. No rush.
