Carlsbad Caverns National Park
The otherworldly subterranean landscape of Carlsbad Caverns National Park is—justifiably—New Mexico’s most famous attraction. Take the self-guided audio tours of the Natural Entrance and Big Room (tickets and headphones are available at the park visitor center). Then sign up for a 1.5-hour ranger-led tour through the four Kings Palace chambers, which lie some 830 feet beneath the park’s surface and contain hundreds of eerie geological formations.
Tune in on Wednesdays at 10PM ET for Top Chef: Boston, the 12th season of Bravo's Emmy-Award winning, hit reality series.
