The Khlongs of Thonburi in Bangkok

At 6 metres across, only narrowboats like flat-bottom boats and longtail speedboats can navigate the Thonburi khlongs (canals). You can hire a colourfully painted long-tail boat (hang yao) from major tourist piers like Rivercity, Taksin, Chang or Maharaj. Agree on the price before departure (usually between 400 and 500 baht per hour). Even so, bear in mind that he's your driver and not your guide – his English may be minimal but he will know where to go.

Ask to explore Khlong Mon, Klong Bangkok Noi and Klong Bangkok Yai, and also the Royal Barges Museum, which contains splendidly decorated boats and barges that are unique to Thailand. Sound tricky? Try a khlong tour or a canal route tour instead – they're hassle-free and include pick-up and drop-off services at your hotel.

Khlong Mon in Thonburi is as quaint as they come. Old and weathered teak homes alternate with modern townhouses, crumbling shacks and the odd temple. Common sights include saffron-robed monks and verdant patches of morning glory or water hyacinth, as well as people scrubbing clothes, sleeping or throwing scraps to fish. This is an older, simpler and altogether sweeter part of Bangkok.

Khlong Bangkok Noi is wider and bolder – more river than a canal. It is lined with factories, temples, navy installations, and homes. A must-see is the Royal Barges National Museum, where you can check out elaborately gilded barges used in solemn royal ceremonies.
