Are you asking how to get from Krabi to Phuket? A private taxi will cost about 2500 - 3000 baht. Or you could take ferry from Krabi via Phi-Phi.

Cheers Sunbear, anything you dont know about Thailand? Given all your experiences in thailand, what 3 places would you choose to do a 3 stop holiday?, well 2 if Bangkok is one of them?

Martin_d,
I only know the prices because I did it this March...although the other way round Phuket to Krabi...took photos of Taxi price schedule in airport...people thought I was a loony...easier than writing it down though. You could probably do it cheaper as some taxi drivers will be open to negotiation...fares have certainly increased with the rise in oil prices though.

3 places I would go to including Bangkok.... Northern Thailand (my favourite part of the country) and Krabi for the beach element.

Still plenty of places I want to get too that I've not managed yet though (Trang, Koh Lanta, Koh Chang for instance)
