Being such a large country, with different states, all unique in their own way, the US has lots of tourist attractions that bring in billions of dollars and millions of people each year. But let’s take a look at some of the least known ones, the natural wonders this big country has to offer.
#1 Great Sand Dunes National Park, Colorado
Here you can trek up a 4 km (13,000 ft) mountain, as these are the tallest sand dunes in North America. You can also chill in the Medano Creek, with an awesome background of mountains and dunes.
