Carlsbad Caverns in July: what the park service says

July holds Carlsbad Caverns' big bat event. On the third Saturday of the month, the park gathers at dawn, around 5 a.m., in the Bat Flight Amphitheater to watch the bats dive back into the cavern, followed by bat activities in the visitor center through the day (some need signing up the day before). Every evening in July, the regular Bat Flight Program typically starts around 7:30 p.m. Both are free.
