    Singapore's public transport system is one of the best in the world, so you should have no problem finding your way around like a local. There are three main forms of public transport that you would find in any other major city－trains, buses and taxis.

TRAINS

    Trains run from 6:00 am to midnight. Single trip tickets start at 80 cents. If you buy an EZ-Link card for $15, you can ride the trains and buses as you like.

If you need more information, just call Transit Link on 1800 767 4333.

BUSES

    There are several bus services in Singapore and fares start at 80 cents. Be sure always ask the driver the cost of your ticket as he cannot give change.

If you need help, just call Transit Link on 1800 767 4333.

TAXIS

    There are three main taxi companies－City Cab (6552 2222), Comfort (6552 1111) and Tibs (6552 8888). Booking can also be easy by calling the numbers listed above.

RENTAL CARS

    Driving in Singapore is a pleasure and if you like to travel at your own pace, renting a car is a good choice. Renting takes away the hassle of getting to places around Singapore. Just sit back and enjoy the city. It also means you'll get to see a lot more that a trains or a bus won't let you see.

    For car rental, call Avis on +65 6737 1668.
