Picturesque Phang Nga Bay is surrounded by several dozen small islands, a few of which have cruise ports. Most however dock at Phuket and some itineraries include overnights, which allows visitors plenty of time to explore the bay, most of which is part of the Phang Nga Bay Marine National Park. The bay is home to dozens of species of flora, fauna and sea life. Any number of water-based excursions, including snorkeling and diving, are on offer.
