Can anyone give me info on using the train system to get from Bangkok to Krabi

Krabi is not the easiest place to get to by train. You can take an overnight train to Trang and then by bus on to Krabi. I have not done this route as I usually fly to there.

I just returned from Krabi 10 days ago and it is definetely worth your time to fly there. We flew on Thai Airways and purchased tickets on expedia.com - I think they were $115 round trip. Bangkok Airways and PB Air also fly to Krabi, but I believe with each you need to connect in Phuket.<BR><BR>Enjoy you time in Krabi - its amazing!

PB no longer fly to Krabi. Train to Surat Thani and take the bus, about 3 hrs

There are definitely flights with Thai Airways from Bangkok to Krabi but they get full quickly, as there are only a couple of flights a day. We got stuck taking a "super VIP" bus b/c the flights were sold out. 11 hour overnight bus - leaves at 6:30ish PM arrives around 5:30AM. You can book the bus through a travel agent. A little bumpy, but otherwsie not too bad of a ride. Cheaper than flight $20ish vs. $60.

Do note that Krabi is not that far from Phuket. The beaches of Krabi are mainly around Ao Nang. From Phuket airport to your beach hotel would take less than 2 hours. Bangkok-Phuket more than 12 flights per day. Thai flys just 2 x daily Bangkok to Krabi.
