The good part about Garden of the Gods was that it is free to get in. The best way to really see the entire park is to walk thru it, but this will take all day to do. If you drive thru the park, you can finish very quickly and you may not see all the rock structures and formations. The red rock formations are really nice to see, but if you are not much into rock viewing, Garden of the Gods won't be much excitement for you. In addition, if it is hot outside, you can get discouraged very quickly and leave without see all the formations.
The best rock formation to see if the "Balancing Rock". It is fun to take pictures of this, especially when you have friends and family climbing all over this rock. The only rock formation we coudl not find was the "Siamese Twins". We circled the park three times via car and could not find it, so we gave up and left.
In general, this was a nice place, but definately not my favorite place in Colorado. Be prepared to carry water and food in your backpak as you hike thru this park.
