There isnt actually very much to do in the town of Krabi, but it is a really nice, relaxed and cheap place to stay that is close to alot of things. So stayed there a few days, actually a bit longer than I had originally planned, but it was nice. The first full day we went over to Railay bay to have a walk around the beaches/cliffs. Scaled some rocks to get to this view point and ended up finding a way down into this really small secluded lagoon. It was awesome but an effort to get back out of though luckily there were alot of ropes around. Also went over to ao nang one day where you could walk along a sand bar in the sea to a little island. Did some snorkelling and the final day just stayed around Krabi town.
