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.

During the South west monsoon gusts of strong winds blow across the Gardens towards the Uva Valley, making weird sounds. During October to December, when thick mist envelope the gardens, heavy downpours of rain falls more frequent in the afternoon and evenings. The best time to see the gardens is probably from about mid March to the end of April, popularly known as the Nuwara Eliya seasons. The gardens put up their best display of temperate annual flowers, Roses and Orchids during this period.
