From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.

A rich blend of the historic and modern, Zaragoza sits on the banks of the Ebro River. Stroll in the centre of town near San Miguel's pedestrian ways or around the Plaza de los Sitios, where you find boutiques, markets and souvenir shops. A centre for gastronomy, Zaragoza offers food and drink for every budget and taste. But tapas is a must! In 2008, Zaragoza hosted the International Exhibition; the Water Tower, Bridge Pavilion and River Aquarium show off of the city's avant-garde architecture.

The town that gave the country (and port wine) its very name, Porto is Portugal’s second-largest metropolis after Lisbon. Sometimes called Oporto, it's an age-old city that has one foot firmly in the industrial present. The old town, centered at Ribeira, was built on the hills overlooking the Douro River, and today is a UNESCO World Heritage Site. The 14th-century São Francisco church is a main attraction, as are the local port wine cellars, mostly located across the river at Vila Nova de Gaia.

This former fishing village on Portugal’s southern coast has become a popular resort. Spend a day on Alvor’s main beach, or find one of the smaller, secluded coves along the coastline. In the evening, stroll through the town’s narrow cobblestone streets, dine on fresh local seafood, and enjoy live music at one of the many lively bars.

As the gateway to Costa del Sol, Torremolinos is a modern city preserving the great charms of the Andalusian tradition. Here visitors enjoy more than 300 sunny days every year, comfortable temperatures (avg. 19ºC/66ºF) and 7km of beaches along the sparkling Mediterranean. Away from the sea and sand, travellers can explore the old fisherman’s district of “La Carihuela,” or sample the city’s cuisine – including regional favourite Pescalto Frito (fried fish) – in hundreds of restaurants and bars.

Founded in 1565 by the Order of St John as a refuge for soldiers returning from the Crusades, Valletta is now the capital of Malta and a piece of living history. With an unsurpassed collection of original Baroque architecture, fortified city walls overlooking the Mediterranean Sea, and the spectacular Co-Cathedral of St John, which features intricately carved stone vaults and a famed painting by Caravaggio, it is no wonder that this smallest of European capital cities is a world heritage site.
