If you're the adventurous type of couple, go big by visiting the largest waterfall in the world. As water pours down the height of 167 feet, mist rises around you and rainbows form in your view. It's something truly mystical that will leave you speechless. Stay at the nearby Tongabezi Lodge to extend your romantic mood further, and perhaps even take a boat ride to Livingstone Island to see the spectacular falls.
10. Quebec City, Canada
Quebec city is known for its cold and snowy winters, which can actually offer the perfect romantic atmosphere for the couple who wants to cuddle for warmth. You may visit the historic Old Quebec to feel immersed into a 17th century era due to its quaint, cobblestoned streets and a walled fortress surrounding the city, reminiscent of a characteristic European village. Add an extra excuse to stay warm by booking a room in the city's Ice Hotel - it's not you'd need any more ice, but it makes for a unique experience the two of you will never forget.
