We also took ferries so that we can explore the beaches near Aonang. It was a great experience and it was like taking a water bus. The price wasn't expensive and we enjoyed every minute of it. On the way to another beach, we used to encounter people kayaking. There are many shops from where you can rent a kayak and since we didn't indulge in his activity, I do not know the cost of renting though. We also went for elephant riding because my son loves elephant and it was a new experience for him. After our ride, we also went to feed bananas to the elephants. The cost of banana is, of course, separate and not included in the cost of elephant ride. I would not recommend shopping in Krabi because I feel that similar things are much cheaper in Bangkok than this island. Maybe because this such a popular tourist attraction that they charge more for almost everything.
