this november i'm going to thailand, malaysia and maybe kambodcha for 3 to 3and a half weeks. started doing a bit research cause it's my first time going to asia. basicly the route should be bankok-chiang mai-phnom penn(kambodcha)-phuket-kuala lumpur (malaysia). what would be the best way to travell to all these places?? train or plain?
I'd have to say by train: it isn't the easiest (long distance buses would have to be the easiest and cheapest) but it's almost certainly the most interesting. Make sure you stop at plenty of local places if you have the time, like here for example: http://journals.worldnomads.com/simon_monk/post/35426.aspx about 8 years ago
Personally the best way to travel anywhere in Asia is on a motorbike - not the little 150cc scooters you can hire but a proper motorbike. I just rode my BMW R1150GS (i.e. Long Way Round, Long Way Down) from Singapore through Malaysia, Thailand and Laos over Christmas. Having said that, you can also rent good quality Honda Baja 250cc bikes in Thailand and Laos too - these will get you anywhere, especially off the beaten track.
Otherwise it great to take the local busses - and I use the term bus very lightly. I've ridden on everything from a luxurious overnight coach to a utility truck (ute). It's how the locals travel and you get to see and experience much more of the local flavor this way. You might be accompanied by elderly villagers with their weeks supply of dried fish, live ducks and chickens in bamboo cages, sacks of rice, fresh vegetables to boxes of packaged biscuits, scooters, bicycles and even fresh seafood on ice in leaky polystyrene boxes. It's all part of traveling Asia. about 8 years ago
