Question

What famous subterranean tourist site is located in New Mexico?

Answer 1

Carlsbad Caverns. But for your information, New Mexico is not in Mexico, but in fact is in the U.S.A.

This is my help from Washington, DC, United States of America

Answer 2

Carlsbad Caverns National Park

Carlsbad Caverns National Park is located 23 miles south of Carlsbad, New Mexico. Take an elevator or footpaths on a 750 foot decline down into the one of twenty World Heritage sites and experience a place like none other. It is estimated that the birth of the caverns dates back 250 million years. There are several tours available at the National Park both guided or self directed. Base entry fees are good for three consecutive days and range from six dollars for adults to three dollars for children ages 6 to 15. Cameras are welcome but no flash photography please. Regardless of how hot the summer outdoor temperatures may be bring a jacket or sweater. The caves stay a constant 56 degrees year round. Carrying a bottle of water is adviseable. There is a good bit of walking to do even on the shortest tours so wear appropriate shoes with good tread. There are both a gift shop and a restaurant at the park. Don’t miss the flight of the bats at sunset during the summer season. Summer Hours Memorial Day through Labor Day are daily from 8AM to 7PM with the last cave entry at 3:30PM. Winter Hours Labor Day to Memorial Day are daily from 8AM to 5PM with the last cave entry at 3PM.
