Singapore

Singapore is a garden city: hawker centres, a skyline on the bay, and trees taller than some of the buildings.

The trees at Gardens by the Bay are not quite trees. The Supertrees are steel frames up to 50 metres tall, wrapped in more than 160,000 plants, and some of them collect rainwater and solar power for the gardens below.

Trevlo's audio tour of Gardens by the Bay tells how a strip of reclaimed land became one of the city's favourite places to walk. Start when you like. Your first tour is free.
