2 Best Sights in Carlsbad Caverns National Park, New Mexico

The third Saturday in July each year, early risers gather at the cave's entrance to watch tens of thousands of bats return home from their nocturnal search for food. Nature walks and other special ranger programs are offered as well during this free event.

Coinciding with the new or first-quarter moon of every other month, star parties are held outside Living Desert Zoo & Gardens State Park about six times a year. A laser tour and powerful telescope bring the heavens closer. Call for dates.
