The 12 Islands Cruise is one of the most popular trips in Turkey, showcasing the islands of postcard-pretty Fethiye Bay. Swim stops pepper the day, giving you a closer look at the ancient frankincense trees of Boynuzbükü and hilly Zeytin. Tersane is the biggest of the islands – its ink spill shape offers a skinny islet with millpond-still waters. Back in Ottoman times, this place was a port famous for its shipbuilding, but nowadays the hills are scattered with sun bleached ruins. This voyage also squeezes in a couple of refuelling stops, including lunch and a coffee break.
