On the spur of the moment we decided to see Devil's Tower. My husband and I were on a long trip out west and we had done the Badlands and Mt. Rushmore the day before. I didn't quite know what to expect as it is a tower of rock. It was really cool getting views of it as we drove up. The entrance fee was $10, but we had the America the beautiful pass and that can be used here. On the drive to the visitor's center we passed a prairie dog town and those little fellas are so cute! We did the 1.3 mile paved hike around the base and that was very interesting, yes it is a big rock but there is a lot of character in that big rock, there was a nice over look of a valley/river, and we saw some climbers climbing the tower. We did get to see a deer too, which isn't a big deal to us because in Wisconsin there are tons of deer. We went early in the morning which was good because there weren't many people and it was cooler temperature wise for walking. There was a tour group that was on the trail at the same time as us, I think it was a Japanese tour group, they seemed to be enjoying themselves but they were running and snapping pictures as quick as possible it was kind of funny. The trail did take us about 50 minutes and we took our time and talked to the mom of the people who were climbing the tower. We didn't spend much time in the visitors center, but I did spend about 10 minutes in line for the bathroom (bad timing with a tour groups). If you are in the area definately check it out.
