Phuket is an ideal base from which to explore the Andaman region. Many boats leave Phuket for trips around Phang Nga Bay, with its impossibly sheer limestone outcrops that rise out of the sea, many caves and odd shaped islands. Other popular destinations are Phi Phi Island, Racha Islands and the Similan Islands. The Similans are considered to be among the top ten dive sites in the world. Phuket is not all about beaches. If you have time, the interior is definitely worth exploring. There are rice paddies, rubber plantations and small slices of Phuket's remaining rainforest. Phuket Town  is definitely worth checking out.
