Formed over 100,000 years ago, the volcanoes were the dynamic finale to a series of fissure eruptions that coated the surrounding landscape in a basalt caprock.
The park is managed by National Park Service . It offers shaded resting benches along the trail and a restroom. Park is open 9 a.m. to 5 p.m. daily, except Thanksgiving, Christmas, and New Year's Day.
To access the volcanoes exit I-40 at Atrisco Vista Boulevard (formerly Paseo de Volcan) (exit 149) and travel north 4.8 miles to park access.
