Walk on the wild side

Get that stale air out of your system at Changi’s five themed gardens. Our faves include Terminal 2's Sunflower Garden, where you'll find over 500 cheery flowers. But perhaps the best is Terminal 3’s Butterfly Garden, where butterflies flit around and sip on ripe pineapple all day. Terminals 1, 2 and 3

Catch 24-hour movies

Free movies—what’s not to love? The airport's movie theaters are open 24/7 and constantly play Hollywood blockbusters, so you can nip in for a free screening at literally anytime of the day. Terminals 2 and 3

Take a dip in the rooftop pool

You’d never have thought that you could fit in a workout while waiting for your flight. The Ambassador Transit Hotel at Terminal 1 has a rooftop pool that overlooks the runway, as well as a gym and Jacuzzi (free for hotel guests, a tad steep at $13.90 for non-guests). There are shower facilities for afterwards, too. Terminal 1

Get your game on

The Entertainment Deck at the Terminal 2 Departure Transit Lounge is a haven for gaming geeks. There’re LAN gaming, Xbox Kinect and PlayStation consoles, as well as a 50-inch plasma television and music system. Terminal 2

Take the ultimate selfie

Get snap-happy at Terminal 1’s The Social Tree, a snazzy high-tech interactive installation surrounded by eight touch-screen photo booths. You can superimpose your photos onto the colorful tree structure, email snapshots to friends and family, and even upload them onto social media. Terminal 1

Drink up

Sip on beer, wine or cocktails at the La Cave Wine Bar at Terminal 1, which is an outdoor bar located in the Cactus Garden. Other places to drink include Harry’s and Hari’s Pub. Terminal 1

Get a rubdown

Book yourself an invigorating treatment at Wellness Spa—we can't think of anything better to do before or after a flight. The Oxygen Therapy is especially recommended for travelers suffering from jet lag and cabin pressure-induced headaches. Terminal 2
