Seoul is a city with the perfect mix of old and new, historic and modern. The ancient temples and palaces are lit with modern neon lights, creating an almost fantastical vibe. One of your first stops should be Seoul’s Bukchon Hanok Village.
Among other very visit-worthy sites are the Jogyesa, a 620-year old Buddhist temple, the Gyeongbokgung Palace and the Dongdaemun Design Plaza, a modern shopping mall with seven levels.
Budapest, Hungary
Even though Budapest has a bitter history, it has certainly managed to rebuild and turn itself into a city that's definitely worth visiting. The capital of Hungary, Budapest has tons of sites to see, including the famous Parliament, the beautiful Chain Bridge and the ancient Buda Castle, a palace that dates back to the 13th century.
If you're in the mood for stepping into a fairytale land, visit the Neo-Gothic Fisherman's Bastion.
Amsterdam, Netherlands
Amsterdam is a world-famous tourist destination, housing history, culture, art, and beautiful nature. With its incredible canal system, and its extremely narrow, 17th century houses, this city is the grand capital of Netherlands.
Rent a bike and ride around the city, stopping to see the Rembrandt Museum, the Anne Frank house and the impressive Van Gogh Museum. If you happen to be lucky enough to visit during springtime, make sure to not miss the wondrous tulip festival.
Chicago, USA
Dubbed the Windy City, Chicago has astounding views of the grand Lake Michigan, unique gastronomy and ultramodern skyscrapers. If you're looking for the complete experience, go have some Chicago-style hot dogs or a deep-dish pizza at any of the local eateries.
Take the "L" train to see Chicago's famous neighborhood of Wrigleyville, or visit some of the city's best restaurants at Hyde Park.
Toronto, Canada
Canada has a few cities on this list, and Toronto should definitely be one of them. The waterfront views, the stunning green nature and a vibrant modern city center make Toronto one of Canada's most visit-worthy cities.
Visit the Cloud Gardens Conservatory, the Edwards Gardens or the Allan Gardens to soak up some beautiful nature. Another thing you can't miss when visiting Toronto is the magical ferry ride to the gorgeous Toronto Islands.
