Clinging to a hillside above the highway running south east out of Nuwara Eliya, Hakgala Botanic Gardens date back to 1861. For the modest entrance fee (2,000 rupees for an adult), you get fine views over the Uva Valley below as you wander around the terraces, flowerbeds and arboretums, complete with bands of monkeys. With about 28 hectares to explore, these gardens should occupy you for at least an hour or two.
