Friendship Park

Friendship Park splash fountain area at Carlsbad Caverns National Park with shaded pavilions and picnic tables.

The Big Room stretches before you as a vast limestone chamber with passages weaving along the walls. It measures about 4,000 feet in length, 625 feet in width, and 255 feet at its highest point. The cave formed when sulfuric acid dissolved Capitan limestone, and later carbonate processes produced stalactites, stalagmites, and other speleothems.
