By Boat : Thap Lamu Pier, located 70 kilometres north of Phang-nga at Amphoe Thai Mueang, is the nearest point to Similan. A boat trip takes around 3 hours. There is no regular boat service for travellers to the island. Boats leaving from Thap Lamu are suitable for group tours and the boat rentals range from 8,000-10,000 baht, depending on various factors. It is sometimes possible for individuals to hitch a ride or pay a reasonable fraction of the rental cost on a boat chartered by a group. This method is by no means certain and should be an option only for the adventurers who have time to spare.
