It is not near as impressive in pictures as it is in person. I can't describe the feeling that you get as you drive closer and closer to Devils Tower. You can see it from a distance and it seems as if you just can't get enough pictures of it - sort of like the movie, "Close Encounters of the Third Kind." There were park rangers around to answer questions and giving lectures about the monument as well as trails that you can walk on around the tower! Make sure you stop by the museum/gift shop - they have lots of interesting displays and information about Devils Tower. We were even able to see some people climbing the tower (with our binoculars) while we visiting. You will enjoy watching the prairie dogs on your drive up to the monument. Even though this exhibit is 30 min off the interstate, it is well worth the drive!
