What To Do
Eat seafood: Dine in open-air taverns and restaurants next to the spectacular caldera. Local specialties such as octopus in onion sauce and mussels with rice and raisins will keep you coming back night after night.
Take in the views: Peer into a live -- and at times smoldering -- volcano on an excursion to Nea Kameni, one of the two Burnt Isles. Hike to the top of the 430-foot tall mountain and walk around the edge of the crater for an once-in-a-lifetime view.
Go to the opera:
Even if you're not a fan, it's worth seeing an opera at the Prague National Theatre if only to admire the space's auditorium. Check NationalTheatre.cz for performances and tickets during your trip.
Visit landmarks:
Santorini is punctuated with blue-topped domed cathedrals, but don't miss the modern Greek Orthodox cathedral of Panagia Ypapantis in the southern part of the town of Fira. Another not-to-miss is the monastery of Profitis Ilias, located at the highest point on Santorini, boasting views of Crete's mountains on a clear day.
Shopping
The narrow pedestrian alleyways of Firá and Oía are lined with souvenir shops and jewellery stores selling handcrafted gold and silver pieces. Buy Santorini's renowned white wine and vinsanto (dessert wine) at a vineyard, where you also get to try a few glasses before buying.
Island hopping in the Cyclades
From Santorini, enjoy a day trip to one of the nearby islands or stay longer to explore sugar-cube villages and relax on stunning beaches in Mykonos, Naxos and Ios.
Discover the surreal lunar landscape of Milos and the undulating hills and beautiful Venetian buildings of Siros. Get in touch with Greek history by wandering around the archaeological wonders of tiny Delos Island.
