Singapore Botanic Gardens

Singapore Botanic Gardens is a large botanical garden in Singapore listed as a UNESCO World Heritage Site. It contains tropical plants, several themed gardens, and the National Orchid Garden within its grounds. The site held a herbarium and library about 150 years ago, and admission is now free except for the National Orchid Garden, which charges a separate fee. The grounds are very large, hot, and humid, so seeing all of them takes several hours.
