Saint John is said to have written the Book of Revelations in a cave on Patmos, and today the spot is marked by the hillside Monastery of the Apocalypse. As well as spirituality, the island is known for its beaches and upmarket vibe, with a scattering of stylish restaurants and bars.

Marmaris is one of Turkey’s biggest beach resorts, with the crowds to match. It’s easy to see why so many are drawn here, with a great location on a mountainous bay, but we’d recommend heading further along the coast in search of quieter beaches and picturesque fishing villages.

Antalya is the biggest and busiest city on the Turkish Riviera, though there’s more to this place than just roasting on a beach. The historic Kaleiçi district is full of lovingly restored Ottoman mansions, and top attractions include the superb collection of classical treasures at the Antalya Museum, with pieces from the nearby archaeological sites of Perge and Aspendos.

Named European Capital of Culture in 2017, Paphos actually consists of two towns. Ktima, the Upper Town, is home to elegant colonial architecture and several museums, while Kato Pafos, the Lower Town, is more geared towards tourism, with bars, souvenir shops and the impressive Archaeological Park.

Haifa is Israel’s third city, a bustling and multicultural place where six different faiths live side by side. The city is the spiritual centre of the Baha’i Faith, and the beautiful Baha’i Gardens are a must-see. Many cruise visitors opt to skip Haifa and take an excursion to Jerusalem and Bethlehem, two to three hours’ drive away.

It's difficult to overstate the spiritual significance of Jerusalem, a holy city to three different faiths: Christianity, Islam and Judaism. Whatever your personal beliefs, it's impossible not to be moved by sights such as the Wailing Wall, the Dome of the Rock and the Church of the Holy Sepulchre.

Sun-kissed Rhodes, the largest of the Dodecanese islands, is steeped in history; the medieval heart of Rhodes Town was once home to the crusading Knights of St John, and later fell to the Ottoman sultan Suleiman the Magnificent. The hillside village of Lindos, with its pretty whitewashed houses, is another highlight.

The volcanic island of Santorini (known officially as Thira) is one of the most spectacularly beautiful in the Mediterranean. The pretty village of Oia, with its whitewashed houses and windmills tumbling down the hillside, is particularly photogenic.
