We went on a trip with a speed boat as a part of a group. The islands are very beautiful, but there were a lot of boats and tourists (we went in the begining of the high season). It was supposed to be a snorkeling trip, but I wouldn't really agree that it was, there wasn't much to look at in the water. Still worth it, though, because of the beautiful beaches and great views, but don't expect great snorkeling. Going by speedboat was fun. We paid 1000 bath each, incl. water and lunch which was good.
