Among the most beautiful places in the world, you’ll find black-sand beaches and blue ice caves, granite peaks and glacial ice, the City of Light and a city carved in stone. They include both Mother Nature’s handiwork as well as beauty crafted by human hands.

Keep this list handy for planning your next bucket-list adventure. Here are 21 reasons to plan a trip and soak up some truly superlative sights.
