Hours: Park is open 7 days a week. 8:00am-5:00pm Labor Day-Memorial Day 8:00am-6:00pm Memorial Day-Labor Day Aztec Ruins National Monument is a stunningly well-preserved example of ancestral Pueblo architecture, artifacts, and culture. In addition to original masonry walls towering three stories tall, a number of 900-year old wooden roofs are still intact. On the half-mile self-guided tour, visitors have the opportunity to walk through many original rooms. A reconstructed Great Kiva sits in the center of the plaza and provides insight into the ceremonial lives of the ancient people. Aztec Ruins is still a sacred place to the descendants of its builders, including many modern-day Pueblo tribes in New Mexico and Arizona. The park hosts a number of special events throughout the year: a lantern display in December, an Earth Day celebration in April, Junior Ranger camps throughout the summer, and more. All year there is a free Junior Ranger program available to encourage kids to discover various aspects of the site's history. The entrance fee is $5 per adult. Children 15 and under are free. Interagency annual, senior, and access pass holders and three guests enter free of change. Please check in at the front desk to receive an orientation and a trail guide.
