I am flying round-trip from BKK to Krabi on March 9th and returning on the 19th. My plan was to spend a couple of days in various places, maybe offshore here and there and some mainland spots. My interests are mainly reef and jungle. I see some National Parks to the north and south. Can any of you recommend some key spots to hit in a 10 day visit? There must be some great snorkeling/dive spots. There are also quite a few caves listed as natural attractions scattered throughout. I don't mind getting off the beaten path and away from general tourism. Thanks in advance.
