BEST WAY TO SPEND A DAY:
Charter a sail with Captain Ted. A Bergen County transplant, the sailor and his first mate will take you out on the 41-foot catamaran Blue Lagoon for a sail around the island. Highlights include swimming in the hot springs and the crew's barbecue dinner-a fantastic spread of Greek salad, grilled calamari and shrimp, fresh eggplant salad, and steak.
A clutch of nearby islands are also worth exploring. There is Thirassia island with the whitewashed village of Horio perched at the top of 250 stairs. And don't miss the volcanically active Palea Kameni and Nea Kameni with their smouldering sulphur craters, natural hot springs and bubbling mud pools.
Sail in style with Captain Ted on board one of his gleaming white catamarans. Trips include daytime or sunset tours with seafood and steak barbecue in a private bay, from £88 per person (00 30 694 424 1162; www.santorinisailing.com).
