Tucked away in the serene mountains of the hill country in Sri Lanka, Horton Plains is unlike any of the other 21 national parks scattered throughout the tropical island nation. The highlight of the park is World's End, a sheer cliff with a drop of 4,000 feet, which pulls droves of tourists into the national park every year. Let your inner adventurer loose by embarking on an exciting hike through the montane grassland and cloud forest of Horton Plains to World's End, where you are greeted with mind-blowing panoramic views.
