Hidden away in my treehouse above the sea, I’ve seen very little of the island of Phuket aside from a brief trip to the market. That changed today in a fit of inspired whimsy: I chartered a speedboat off the eastern side of the island and spent the day freewheeling the Andaman Sea. After dropping anchor for a quick picnic and swim on a stretch of beach at Ko Thanan, we headed north towards Phang-Nga Bay, past dozens of islands created by mainland fault movements. Each island is, in fact, a single, massive limestone monolith, upended vertically and pocked round the base with caves which only reveal themselves during the low tide. (Limestone being soluble, the caves are the result of thousands of years of tidal erosion.) You can take a sea kayak and paddle inside the caves if the tide is right, but my timing was off, so I settled for a pee break masquerading as a swim stop beneath the dramatic cliffs before continuing northwards – in a sudden lashing rain – to Ko Phing Kan, or James Bond Island. Used as the setting for the secret lair of Christopher Lee in The Man With the Golden Gun, JBI has become the most famous part of the newly established Ao Phang Nga Marine National Park. In point of fact it’s two islands: the towering Khao Phing Kan, literally “hills leaning against each other,” and Ko Tapu, or “spike island,” where Scaramanga hid the solex laser. If I had to be a super-villain I couldn’t think of a better place to hideaway and plot world domination.
