I prefer the idea of the train than a mini bus from Bangkok, but wonder if the train times would make a trip quite limit in, time wise.
We are interested in doing the Erwan falls, River Kwai and war museums, maybe rafting and possibly seeing some elephants (although that could wait tip our 5 days in chi nag Mai, maybe).
Anything else that I'm missing that would be a nice compliment to 5 days in Chiang Mai straight afterwards?
Would you suggest an organised tour or is it very doable independently? 1 day or 2? (I think if we are spend only one day in Kanchanaburi, i'm worried we might have too long in Bangkok city).
All advice appreciated!
