The Singapore Botanic Gardens is a 74-hectare (183-acre) botanical garden in Singapore. It is half the size of the Royal Botanic Gardens in Kew or around one-fifth the size of Central Park in New York. It is the only botanic garden in the world that opens from 5 a.m. to 12 midnight every single day of the year, and does not charge an admission fee, except for the National Orchid Garden. The garden is bordered by Holland Road and Napier Road to the south, Cluny Road to the east, Tyersall Avenue and Cluny Park Road to the west and Bukit Timah Road to the North. The linear distance between the northern and southern ends is around 2.5 km (1.6 mi).
