Visit the only tropical botanic garden on the World Heritage list
Inscribed 2015, founded 1859
Founded in 1859, the Singapore Botanic Gardens covers 74 hectares in the middle of the city and holds more than 10,000 types of plant, including the most significant living orchid collection in the region.
Why it's unique
It was inscribed by UNESCO on 4 July 2015 and remains the first and only tropical botanic garden on the World Heritage List. That is a specific and checkable distinction — Kew and Padua are on it, and neither is tropical.
The reason it qualified is scientific rather than scenic. This is where Henry Ridley worked out how to tap rubber trees without killing them, and the plantations that followed reshaped the economy of the whole peninsula. The gardens are a working research institution that happens to be free and open from five in the morning.
Before you go
Free, except the National Orchid Garden, which is ticketed and is the part most worth paying for.
Open 5am to midnight. Go early — it is genuinely cool before eight and unbearable by noon. Enter at Tanglin Gate for the heritage core rather than Bukit Timah Gate, which is the modern end.
