Carlsbad Caverns in August: what the park service says
In August, plan a Carlsbad Caverns day in two halves. By day, a timed entry ticket gets you into the cavern; you can walk in through the Natural Entrance between 9:30 a.m. and 2:30 p.m. and must be out by 3:30. Come back at dusk for the free, no-reservation Bat Flight Program at the Natural Entrance amphitheater, and leave phones and cameras in the car: devices are banned to protect the bats.
