Petroglyph National Monument
Petroglyph National Monument information
The lava field preserved in this large desert park, west of the Rio Grande, is adorned with more than 20,000 ancient petroglyphs. Take exit 154 off I-40 to reach the visitor center, 5.5 miles northwest of Old Town, and choose a hiking trail. Boca Negra Canyon is the busiest; Rinconada Canyon – the longest at 2.2 miles round-trip – offers the most solitude; and Piedras Marcadas holds 300 petroglyphs. Smash-and-grab thefts have been reported, so don't leave valuables in your vehicle.
