Petroglyph National Monument is a day-use park, which means the visitor center and each of the trailhead parking lots close at 4:30 pm. Boca Negra Canyon is open daily from 8:30 am to 4:30 pm, with last entry at 4:00 pm daily. Visitors are allowed to hike the trails at the Volcanoes Day Use Area, Rinconada Canyon, and Piedras Marcadas Canyons from sunrise to sunset by simply parking outside of the gated parking lots.
It is important to know that there are no petroglyph viewing trails at the visitor center. (If you are being dropped off at the visitor center, please ask the driver to wait for you since you will need to be driven to the actual petroglyph viewing trailhead.) You do not need to go to the visitor center prior to your hike. If you opt to go to the visitor center it is located at the intersection of Unser Blvd. NW at Western Trail. Please click on the "Directions" link to find the correct driving directions and GPS way points to the visitor parking areas within the monument. The visitor center is located at GPS Lat: 35.139 Long: -106.711
While at the visitor center, park staff will inform you of your trail options based on your timeframe and the degree of difficulty of the trail, then provide you with driving directions to the trail of your choice. Be sure to get your official park brochure and trail maps while there because you may not make it back by 4:30 pm.
Travel time through the park is at least 30 minutes to 4 hours, though the average visit is 1-2 hours.
