Horton Plains National Park
Horton Plains National Park is noted for elephants, big-eyed, nocturnal slender loris, sambar deer, leopards—some of them black or melanistic—and big, shaggy bear monkeys with purple faces and white beards. (Melanism can occur more frequently at high-altitude light exposure.) Endemic birds include Ceylon white-eyes, dusky blue flycatchers, yellow-eared bulbuls, and powerful mountain hawk-eagles. Scenically the park is famous for stunning World’s End precipice dropping startlingly from 7,200 feet (2,200 m) almost straight down for 2,300 feet (700 m).
The altitude variations encourage plants possible only here.
