El Malpais means "the badlands" in Spanish and this enormous National Monument and National Conservation Area is located south of I-40 midway between Gallup and Albuquerque.
Bat Cave is another lava tube cave home to little brown bats, pallid bats, and Townsend's big eared bats which live and hibernate in this cave and others in the monument year round. The cave is also the summer home to Mexican free-tailed bats. At dusk, bats can be seen flying from the entrance to forage for insects. (Please do not enter bat cave or otherwise disturb the bats).
If visiting this area with small children or on a very hot day, I recommend going back the way you came at this point.
If you are up for further exploring you can continue on to Lava Trench area, then to the El Calderon Cinder Cone.
