Day 1 Dubai, United Arab Emirates

Dubai sits on a golden sandy coastline in the Arabian Gulf, where the warm azure waves of the sea meet the desert. A high-rise oasis, this city is a pleasure-dome surrounded by dunes; one of the most fashionable on the planet thanks to its ability to satisfy the needs of legions of demanding vacationers. Dubai is about having fun—and it's one big adult playground.Nature plays her part here, with year-round sunshine, gorgeous beaches, dramatic arid landscapes, and warm waters, but it's the man-made attractions that make Dubai so alluring. You can launch yourself into high-adrenaline desert adventures, diving and water sports, and some of the world's best golf courses. The 5-, 6-, and 7-star hotels offer the ultimate in luxury, and the party scene is hot. Shopping malls are the biggest in the world and are packed full of high-class merchandise. And with hundreds of restaurants with cuisine from around the world, you can munch your way from Mexico to Malaysia.Dubai is an Arab country with a long history as a trading port. Traces of its traditional life, customs, and architecture can still be seen and explored, but today and tomorrow are much more important than yesterday. Almost every building in this metropolis is less than 20 years old and the most dramatic developments—groundbreaking megaprojects—have just been completed or are still under construction.The city is certainly unique. Islam is its anchor, but it has opened its doors to the rest of the world and has invited them in to work, rest, and play, which creates a truly international atmosphere. Unashamedly modern and materialistic, life here takes place at breakneck speed. The landscape is stark, the confidence is sky high, the can-do spirit is palpable, and the bling is in your face. Dubai produces strong reactions in people, but one thing is certain—love it or loathe it—you will not forget it. It is without a doubt, one of the world's true must-see destinations.Shisha: Smoke Without Fire. Emirati men love socializing, but as they don't drink alcohol they get together over coffee and shisha instead of a drink at the bar after work. The shisha, or hookah, is a smoking device, usually made of glass, that filters smoke through water before it reaches the smoker's mouth. Shisha tobaccos are aromatic and are often mixed with apple, cinnamon, or cherry, so their taste isn't as strong as other tobaccos. Smoking shisha is said to induce relaxation—but you'll have to decide if it's for you!

Day 3 Muscat, Oman

Oman's capital city is hemmed in on one side by spectacular jagged-peaked mountains and on the other by royal blue sea. The architecture is a traditional, sophisticated arabesque blend of white-washed, low-rise buildings surrounded by manicured palms, intricately designed domes set atop the minarets of the mosques, sand-colored villas, a surprising blend of modern art installations, like a giant incense burner that towers over the Corniche, and ancient forts set in the rocky hills. Though tradition abounds, from distinct, local cuisine to the widely worn national dress, the dishdasha, Muscat is a completely modern city, featuring opulent luxury hotels, international restaurants, excellent cellular and data service, sprawling shopping malls, pristine beaches, lively nightlife, world-class performing arts, and a highly educated population, most of whom speak English, Arabic, and often Hindi. Muscat is the ideal base for exploring other areas of the country since many of the most desirable destinations are within a few hours' drive.

Day 8 Jeddah, Saudi Arabia

Day 10 Safaga, Egypt

Port Safago has been undergoing a transformation, slowly metamorphosing into a holiday rsort. Like other cities on the Red Sea, the commercial port town sits close to great offshore dive sites. Unlike others, however, tourist development hasn't taken off in a meaningful way. But if the mass tourism in Hurghada is a turnoff, Safaga offers a small-scale and much more low-key alternative, though the best dive sites can still be seen on a day trip from Hurghada. Safaga is also the closest beach resort to Luxor and the Valley of the Kings, which lies 200 km (124 mi) to the southwest; when cruise ships offer land excursions to Luxor, they often do so through Safaga.

Day 15 Santorini, Greece

Undoubtedly the most extraordinary island in the Aegean, crescent-shape Santorini remains a mandatory stop on the Cycladic tourist route—even if it's necessary to enjoy the sensational sunsets from Ia, the fascinating excavations, and the dazzling white towns with a million other travelers. Called Kállisti (the "Loveliest") when first settled, the island has now reverted to its subsequent name of Thira, after the 9th-century-BC Dorian colonizer Thiras. The place is better known, however, these days as Santorini, a name derived from its patroness, St. Irene of Thessaloniki, the Byzantine empress who restored icons to Orthodoxy and died in 802. You can fly conveniently to Santorini, but to enjoy a true Santorini rite of passage, opt instead for the boat trip here, which provides a spectacular introduction. After the boat sails between Sikinos and Ios, your deck-side perch approaches two close islands with a passage between them. The bigger one on the left is Santorini, and the smaller on the right is Thirassia. Passing between them, you see the village of Ia adorning Santorini's northernmost cliff like a white geometric beehive. You are in the caldera (volcanic crater), one of the world's truly breathtaking sights: a demilune of cliffs rising 1,100 feet, with the white clusters of the towns of Fira and Ia perched along the top. The bay, once the high center of the island, is 1,300 feet in some places, so deep that when boats dock in Santorini's shabby little port of Athinios, they do not drop anchor. The encircling cliffs are the ancient rim of a still-active volcano, and you are sailing east across its flooded caldera. On your right are the Burnt isles, the White isle, and other volcanic remnants, all lined up as if some outsize display in a geology museum. Hephaestus's subterranean fires smolder still—the volcano erupted in 198 BC, about 735, and there was an earthquake in 1956. Indeed, Santorini and its four neighboring islets are the fragmentary remains of a larger landmass that exploded about 1600 BC: the volcano's core blew sky high, and the sea rushed into the abyss to create the great bay, which measures 10 km by 7 km (6 mi by 4½ mi) and is 1,292 feet deep. The other pieces of the rim, which broke off in later eruptions, are Thirassia, where a few hundred people live, and deserted little Aspronissi ("White isle"). In the center of the bay, black and uninhabited, two cones, the Burnt Isles of Palea Kameni and Nea Kameni, appeared between 1573 and 1925. There has been too much speculation about the identification of Santorini with the mythical Atlantis, mentioned in Egyptian papyri and by Plato (who says it's in the Atlantic), but myths are hard to pin down. This is not true of old arguments about whether tidal waves from Santorini's cataclysmic explosion destroyed Minoan civilization on Crete, 113 km (70 mi) away. The latest carbon-dating evidence, which points to a few years before 1600 BC for the eruption, clearly indicates that the Minoans outlasted the eruption by a couple of hundred years, but most probably in a weakened state. In fact, the island still endures hardships: since antiquity, Santorini has depended on rain collected in cisterns for drinking and irrigating—the well water is often brackish—and the serious shortage is alleviated by the importation of water. However, the volcanic soil also yields riches: small, intense tomatoes with tough skins used for tomato paste (good restaurants here serve them); the famous Santorini fava beans, which have a light, fresh taste; barley; wheat; and white-skin eggplants.

Day 17 Messina, Italy

Home to the Museo Regionale of Messina, known for featuring two of Caravaggio's paintings, the city is also famous for having been the capital of the ancient kingdom of Sicily.

Day 18 Sorrento, Italy

Sorrento may have become a jumping-off point for visitors to Pompeii, Capri, and Amalfi, but you can find countless reasons to love it for itself. The Sorrentine people are fair-minded and hardworking, bubbling with life and warmth. The tuff cliff on which the town rests is spread over the bay, absorbing sunlight, while orange and lemon trees waft their perfume in spring. Winding along a cliff above a small beach and two harbors, the town is split in two by a narrow ravine formed by a former mountain stream. To the east, dozens of hotels line busy Via Correale along the cliff—many have "grand" included in their names, and some indeed still are. To the west, however, is the historic sector, which still enchants. It's a relatively flat area, with winding, stone-paved lanes bordered by balconied buildings, some joined by medieval stone arches. The central piazza is named after the poet Torquato Tasso, born here in 1544. This part of town is a delightful place to walk through. Craftspeople are often at work in their stalls and shops and are happy to let you watch; in fact, that's the point. Music spots and bars cluster in the side streets near Piazza Tasso.

Day 19 Olbia, Italy

Amid the resorts of Sardinia's northeastern coast, Olbia, a town of about 60,000, is a lively little seaport and port of call for mainland ferries at the head of a long, wide bay.San SimplicioOlbia's little Catholic basilica, a short walk behind the main Corso Umberto and past the train station, is worth searching out if you have any spare time in Olbia. The simple granite structure dates from the 11th century, part of the great Pisan church-building program, using pillars and columns recycled from Roman buildings. The basilica has a bare, somewhat somber interior, its three naves separated by a series of arches.

Day 20 Mahón, Menorca, Spain

The capital of Menorca since 1721, Mahon has a impressive natural deep water harbour, which is one of the largest in the world. This, coupled with its strategic location, has made it a stronghold for many nations throughout history. Mahon has an abundance of historical buildings, the oldest being the Arch of Saint Roc which is all that remains of the wall that once encircled the whole town. The island was occupied by the British during the 18th century and Lord Nelson is thought to have stayed there. Indeed, San Antoni Mansion, located on the north side of the harbour, houses a collection of Nelson memorabilia. The legacy of colonial rule can be seen in the muted Georgian style of some of the buildings, but Mahon still boasts attractive examples of neo-Classical, Baroque and Romanesque architecture. With narrow streets to explore, pleasant shaded squares and welcoming pavement cafés, there is something for everyone to enjoy. Please be aware that most shops in town close for a siesta between 1330 and 1730.

Day 21 Barcelona, Spain

The infinite variety of street life, the nooks and crannies of the medieval Barri Gòtic, the ceramic tile and stained glass of Art Nouveau facades, the art and music, the throb of street life, the food (ah, the food!)—one way or another, Barcelona will find a way to get your full attention. The capital of Catalonia is a banquet for the senses, with its beguiling mix of ancient and modern architecture, tempting cafés and markets, and sun-drenched Mediterranean beaches. A stroll along La Rambla and through waterfront Barceloneta, as well as a tour of Gaudí's majestic Sagrada Famíliaand his other unique creations, are part of a visit to Spain's second-largest city. Modern art museums and chic shops call for attention, too. Barcelona's vibe stays lively well into the night, when you can linger over regional wine and cuisine at buzzing tapas bars.
