Available now in the VisitorCenter are our NEW! GPS RANGER UNITS. These units work throughout the park and provide a great and easy way to learn about the park. It is like having your own personal ranger with you. As you drive through the park, stop at the various viewpoints, or take the hiking trails, the GPS Ranger automatically picks up videos that discuss the features in that area. All you have to do is listen and learn. They are a great way to spend the afternoon or day. Stop by the VisitorCenter today to learn more about them and rent yours!
