Copenhagen is one of Europe’s oldest and most popular cities. It’s also one of the cleanest and most metropolitan. The dynamic Danish capital features progressive modern architecture, the must-visit Tivoli Gardens amusement park, stunning palaces, and all the activities and amenities you would expect in a world-class destination. Explore the canals and pretty narrow streets, appreciate beautiful old homes, and find great shopping and people watching on The Ströget.

The Baroque Palace of Oradea is simply epic. Now a museum, the 18th-century building is home to an outdoor bronze and marble statue park, Transylvanian folk art and a collection of animal remains that includes dinosaur fossils. You could spend days here, but try to make some time for other Oradea attractions, such as the beautiful Art Nouveau buildings of Str. Republicii, the astronomical clock of the Biserica cu Lună, and the Băile Felix thermal spa.

This compact Scottish city is perfect for exploration by foot — travellers can easily find their way from the lovely River Ness to historic Inverness Castle and St. Andrews Cathedral, and beyond to the events at Eden Court and the busy Victorian Market. It’s also an ideal base for exploring the Highlands, with the mysterious Loch Ness (and famed local resident Nessie), Culloden Battlefield and the Bronze Age Clava Cairns just a quick drive away.

The “Red City” of Marrakesh is a magical place, brimming with markets, gardens, palaces, and mosques. Exploring the intimate courtyards and snaking alleyways of the historic Medina can easily eat up a day. Find inner peace at the serene Jardin Majorelle or take in the beauty of one of the city’s historic mosques (taking note that, unless you are Muslim, you are not allowed to enter).
