Just a few miles northeast of Phuket is the star attraction – Phang Na Bay. Here are more than 100 islands with geology varying from low, gently sloping hills to the sheer-sided limestone Sea Mountains (karsts) that rise vertically out of the water to stunning heights. Images of Phang Nag and its steep, majestic and strange outcrops have travelled the world.While the bay itself is not large, the number of islands, inlets, mangrove channels and sea caves to be explored ensures that no matter how long a yachtsman spends here, new experiences will always be around the corner.
