If you currently think your neighbourhood coffee shop is nice, you might want to stay out of Vienna’s coffeehouses. After you’ve gotten used to these palatial, yet welcoming cafes—and their delicious coffee and Sacher torte—your local café will pale in comparison.

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.

Faro is the best-known city in Portugal’s deservedly famous Algarve region. There’s an archaeological museum and a “Bishops’ Palace,” a Renaissance cathedral that was heavily bombed during World War II, but later rebuilt. Nearby in Estoi are Roman ruins, and Albufeira, also nearby, is a formerly quaint fishing village influenced by the Moors in the 8th century. It’s situated in a cliffside location, and has become famous for its beaches (there are 20) and nightlife.

The name "Chattanooga" comes from the Creek Indian word for "rock coming to a point". This refers to Lookout Mountain, one of the city's major attractions.

Back down on the ground, don't miss the world's largest freshwater aquarium: the Tennessee Aquarium. History enthusiasts will love the city's museums dedicated to Civil-War, Native-American and 20th-century history. More than anything, Chattanooga is a scenic city, full of natural wonders waiting to be explored on foot or by car, bike or train.
