Top 10 most beautiful cities.British painter Francis Bacon once said that “beauty is in the eyes of the beholder”, so ranking the beauty of cities, and what they have to offer to their visitors, may sound like mission impossible. Some travelers prefer cities where they can spend days exploring ancient wonders and world-class museums, while others are drawn to cities with breathtaking skylines, urban vistas and modern architecture. But although we all have our personal favorites, there are some cities that are so exceptionally beautiful – whether it be because of their historical character or natural setting – that they should be on everyone’s bucket list.  If you’re looking for a destination with urban pleasures, consider visiting one of my favorite 10 cities in the world.No other metropolis in the USA is as loved by its inhabitants as the Bay City, which enjoys one of the world’s most gorgeous settings. Artsy, bohemian and stunningly beautiful, San Francisco’s main draw is it spectacular bay, which is surrounded by 43 hills ranging upward from 200 to 938 ft (60 to 285 m). With an abundance of attractions, such as bell-ringing cable cars, spectacular bridges, infamous Alcatraz, the Ferry Building (a foodies paradise) and of course the sea lions at Pier 39, it’s best to explore this magnificent city on a bike.Without a doubt, Hong Kong, also dubbed the “Pearl of the Orient” has one of the most photographed and beautiful city skylines in the world. The towering skyscrapers and futuristic buildings that are set against the lush mountain backdrop create a breathtaking, urban scenery that is unmatched in the world. Besides its skyline, Hong Kong is also known for its vibrant lifestyle, friendly people, a splendid harbor, loads of shopping and its wide range of restaurants and cuisines.The Czech capital is dubbed “the city of the thousand spires” because of its many historical monuments that have been beautifully preserved and date from practically every period in history. Prague’s most famous attraction are the bridges that cross the Vltava River, especially the amazingly elegant Charles Bridge, but the stunningly beautiful Old Town Square and Prague Castle are equally impressive. Add the cobblestone streets and atmospheric alleyways that zigzag through town, and you know that few other cities delight the senses as much as Prague.
