Botanic Gardens at Hakgala were established in 1861 for the purpose of experimentation and promotion of Cinchona cultivation in Sri Lanka. The gardens lying in the hill country among Sri Lanka's tea plantations in the Nuwara Eliya district are located along the Badulla Road, 9.5 km South-east of Nuwara Eliya, the popular holiday resort. Situated at an elevation of about 1745 m above mean sea level, Hakgala Botanic Gardens, about 28 hectares in extent, lie under the shadow of the Hakgala Rock (meaning “Elephant's jaw rock”). This massive rock towers to a height of about 2,200m behind the gardens and the surrounding forest reserve like a solitary giant. The temperature ranges from 3°C to 15° C. While the lowest recorded was 3° C. The gardens receive rainfall from two monsoons. The South West from May to August and the North East from October to December, the annual average rainfall being about 2300 mm. The flora of the gardens is distinctly sub tropical and consists of representatives of the indigenous, montane flora intermingled with those introduced from other subtropical countries, systematically planted in various sections of the gardens. Hakgala Botanic Gardens open daily from 8.00 a.m. to 5.30 p.m.
