Beat the notorious Bangkok traffic jams by taking the BTS Skytrain - although it has a limited route, it's great for getting around several of Bangkok's hotel and shopping districts. Trains are nicely air-conditioned, run from 6am until midnight and you can get a day pass for 100 baht (about £1.50). There are 3 interchanges with the new subway system - plus the public riverboat service at Saphan Taksin station.
