Carlsbad Caverns in April: what the park service says
April is when Carlsbad Caverns' bat season starts: the park service says hundreds of thousands of Brazilian free-tailed bats live in Carlsbad Cavern from April through October, and watching them stream out at dusk is a park tradition. Going into the cavern itself still needs a timed entry ticket; reserve your entry time ahead, then pay for the entrance ticket at the visitor center (open 9 a.m. to 5 p.m.).
