The underground world can hide many mysteries and beautiful things. Under the rocky slopes of Carlsbad Caverns National Park in the Guadalupe Mountains in southeastern New Mexico there’s an ample system of caves consisting of 118 caves and many hundred miles of caverns and tunnels, which were formed after the sulfuric acid dissolved the surrounding limestone. The Big Rom is actually the largest of them, being 1.2 km long, 191 meters wide and 78 meters high at the highest point and covers a floor space of 33,210 square meters.
You will also find here a cafeteria – 750 feet underground, which is located at the head of the Left Hand Tunnel, where the elevators from the visitor center exit into the cave.
The Underground Lunchroom was established in 1928, two years before the cave became a national park, and it all started because at that time it was a desperate need for food and drink for the tourists exhausted by the six hours walk needed for getting in and out the cavern’s Big Room.
Aside from serving food, here can be found also a souvenir store from where you can buy t-shirts and a small selection of other items. An interesting thing you can do here is to write and send postcards from underground because there is a mailbox in the caverns and you can stamp your postcard “Mailed from 750 feet below underground”.
