I am an advocate of U.S. road trips as a cost-effective and adventurous way to spend one’s summer vacation. One of my favorite things to do while I’m on the road is to enjoy the variety of “natural wonders” the U.S. has to offer. Here are some of my top picks for you to check out the next time you find yourself on the road and in search of some natural beauty. Many lodgings in these areas fill up quickly for the summer months, so I recommend planning your natural getaway in advance
