Compact Singapore takes less than an hour to drive from end to end but there’s a lot packed into this small country. For a first-time visitor, three to four days is usually sufficient to see the main highlights and get a feel of the top things to do in Singapore.

If you’re really short on time, plan a layover with at least 5.5 hours and you can join one of three free transit tours organized by the excellent Changi Airport for a quick taster of what the country has to offer.
