At the Petroglyph National Monument, there are approximately 20,000 carved images in stone that depict animals, people, crosses, and other images. Set on the western edge of Albuquerque, a hike up the park trail teaches about the local geology, which is dotted with ancient volcanoes. Kids can explore and earn a junior ranger badge; check in at the visitor center. It's rarely if ever crowded at this attraction, and looking west across the mesas, you can see some of the oldest volcanoes.
