Monolithic gates still protect Amersfoort, a well-preserved medieval city that remains connected to its history. Built into the foundations of 13th-century defensive walls, the Muurhuizen wall houses are one of the city’s most intriguing features. Art enthusiasts should visit the Mondriaan House (birthplace of abstract artist Piet Mondriaan) and the Armando Museum, a collection of works by the famed Dutch painter.

A sizable city in its own right, Arnhem is best known today as the site of one of the most famous battles of World War II. Given city rights in 1233, it has long been at the centre of conflicts because of its strategic location on the banks of the Rhine River. The Battle of Arnhem, part of Operation Market Garden, was fought in September 1944. Advancing Allied forces, in large part due to a series of mistakes, failed to secure a key bridge and suffered defeat, delaying the Allied advance into Germany until the following spring. The 1977 film "A Bridge Too Far" was based on the events here.

Eindhoven is one of the oldest cities in the Netherlands, but you’d never know it from the high-tech industry and cutting-edge design it’s currently known for. If you have kids obsessed by all things wheeled, they will love the trucks at the DAF Museum.

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.

Many people travel through Frankfurt for business, as it's a major transportation hub and an industrial and financial metropolis. Of course we know that business travellers hate to have any fun on the road (wink), but it's worth lingering in Frankfurt if you can. The 2,000-year-old city has much to offer: skyscrapers, the Main River, a famous opera house, thriving theatre district, zoo, pedestrian shopping street, parks, scores of bars and dance clubs, and more than 50 museums.

In Hinduism, Manu was said to have survived a great flood that destroyed the rest of the world. He then recreated mankind in this Kullu Valley town. What a rush, huh? No wonder the towering peaks and verdant terrain of Manali attracts adventure travellers, with heli-skiing, hiking, mountaineering and river rafting the favored active pursuits. Come down from your endorphin high by breathing deeply at the four-story, wooden Hidimba Devi Temple, which sits in the middle of a nearby deciduous forest, or take a medicinal soak in the hot springs burbling from the ground a 30-minute walk from town.
