The highlight of this full-day trip is the Emerald Cave in Koh Mook which is a place of great scenic beauty. Koh Kradan was the first place to be used as the location of the yearly underwater wedding ceremonies that take place in southern Thailand. Nearby Koh Cherk and Koh Ngai are very pretty and a must for snorkellers. For a day out to a peaceful and beautifullocation it is hard to beat this tour.
