This was the start of a week long vacation through some of our wonderful national parks. I wasn't certain what to expect when I got to Craters of the Moon. I am facinated by lava flows and this National Park blew my mind! What a bizarre place of beauty and so surreal! There are so many different formations to view that I needed and extra day to enjoy all that the park had to offer. I can see why the astronaunts used this location before going to the moon. This is a must see for anyone that travels through in the Idaho or west Wyoming area.
