Head to Yellowstone National Park, where you can see an ancient volcano framing a dramatic landscape and showing natural phenomena.

In addition, there are over 12 campgrounds for a camping experience you will never forget.

The San Antonio River Walk is another spot you can’t miss. It’s ideal for wandering around, enjoying some local food, or looking for souvenirs.
