Amsterdam is truly a biker’s city, although pedaling along the labyrinthine streets can get a little chaotic. Stick to walking and you won’t be disappointed. The gentle canals make a perfect backdrop for exploring the Jordaan and Rembrandtplein square. Pop into the Red Light District if you must—if only so you can say you’ve been there. The Anne Frank House is one of the most moving experiences a traveller can have, and the Van Gogh Museum boasts a sensational collection of works.

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.

In the "city of dreaming spires", academia takes centre stage. Gaze out at Oxford's world-famous colleges from the top of St Mary's Church tower before heading into the city's pedestrian-friendly streets. The University's Botanic Garden and Ashmolean Museum are Britain's oldest. Follow your nose to the Covered Market for the makings of a picnic to enjoy on a punt or in the University Parks. Mix the historic and modern with visits to the 12th- century village church of Iffley and trendy Cowley's ethnic shops and music venues.

Over the centuries, many cultures have added their mark to this prized piece of land. Today, you can experience those influences firsthand by exploring Istanbul’s mahalles (neighbourhoods). From the holy sites of Sultanahmet and the 19th-century European elegance of Beyoğlu to the high fashion of Nişantaşı, the vibrant café society of Kadıköy and the football-loving streets of Beşiktaş, it’s easy to see why travellers say that Istanbul isn’t just one city, but many cities within one.

Ronda’s most striking feature is the Puente Nuevo, which spans a gorge over 300 feet deep. Can you guess when the "new bridge" was built? 1793. That should give visitors an idea of how unchanged Ronda has been over the years. It’s also known as the birthplace of modern bullfighting. The town’s bullfighting ring is only used once a year, at the Feria Goyesca, but it’s also a museum where you can learn about the history of this traditional (yet controversial) sport.
