A pre-dawn pickup on Koh Samui hands you a travel mug and a towel as the island’s lights slip behind the speedboat. Within an hour the shoreline thins, and the Gulf of Thailand opens into a bright flat expanse; the boat slices toward islands whose white sand and steep rock draw nearer with each swell.
