Hong Kong is one of the few places in the world where a 700-year-old fishing village sits minutes away from the headquarters of international banks.

The city has more than 300 hiking trails, including the well-known Lion Rock hike, which ends at a dramatic cliff overlooking Kowloon’s dense skyline.

Niagara Falls, New York, is home to one of the most powerful natural spectacles in North America. More than 3,000 tons of water pour over the edge every second, creating a thunderous roar and a rising mist that can be felt from blocks away. Visitors can stand just feet from the American Falls at Prospect Point or take the iconic Maid of the Mist boat tour, which has operated since 1846 and now features all-electric vessels.
