Caving
NOTE: All caves and lava tubes are currently closed to the public due to white nose syndrome affecting bats which roost in the caves.
Warning: Always bring multiple independent light sources and wear sturdy hiking boots when exploring a cave!
Caves created from ancient lava tubes are found throughout the park, with some cave systems extending as far as seventeen miles. Several caves require permits for entry; check with rangers for current regulations. When caving, assume that your light source could break or be lost while exploring, and bring at least one and preferably two backup light sources. In addition, be aware that the cave floors are uneven, littered with boulders, and often wet, making sturdy shoes a necessity.
Four Windows Cave
Located in the park's backcountry off of county road 42, four windows cave was named for the four openings near its entrance. travel within this cave is relatively easy due to a fairly smooth floor, and gypsum and calcium formations combine with seasonal ice stalagmites to provide interesting sights along the way.
Hiking
Zuni-Acoma Trail
This ancient puebloan trail follows a prehistoric trade route between zuni and acoma pueblos. this is a strenuous 7.5+ mile one-way hike across 4 of the major lava flows in this region. the trail follows rock cairns over very difficult terrain; plan on taking at least five hours to cover the full 7.5 miles.
