Cave Lighting Project
We are undergoing a year-long lighting project in the cavern. Please be aware of caution tape along pathways inside the cave and use due care.
Big Room Self-Guided Tour
The basic tour through Carlsbad Cavern is the Big Room route, a one-mile, self-guided underground walk around the perimeter of the largest room in the cave, the Big Room. An audio guide notably enhances the tour. Taking approximately 1½ hours, this circular route passes many large and famous features including Bottomless Pit, Giant Dome, Rock of Ages, and Painted Grotto. Highly decorated and immense, the Big Room should be seen by all park visitors.
Access to the Big Room is provided by elevators located in the visitor center. The relatively level and well-lit trails make this the ideal tour for visitors with limited time or walking difficulties. Approximately two-thirds of the Big Room is accessible to people using wheelchairs with assistance, an access guide is available at the visitor center information desk. Baby strollers are not permitted in any part of the cave. Bring a baby backpack if you need to carry your child.
Just how BIG is the Big Room? The Atlas of Great Caves of the World by Courbon, Chabert, Bosted & Lindsley published in 1989 states that the floor area of the Big Room in Carlsbad Cavern is 33,210 square meters. 33,210 sq. meters equals approximately 357,480 sq. ft. A football field is 360 feet long (including the end zones) by 160 feet wide or equal to 57,600 sq. ft. By dividing 57,600 sq. ft. into 357,480 sq. ft., you roughly get that 6.2 football fields would fit into the Big Room. In acres, one acre is equal to 4,840 sq. yards or 43,560 sq. feet. Divide 43,560 sq. ft into 357,480 sq. ft. and we find that the Big Room is 8.2 acres in size (more or less).
Anyone under 16 must be accompanied by an adult.

Did You Know?
Jim White is the cowboy credited with being the premier explorer of Carlsbad Cavern. He began to explore the cave as a teenager in 1898, using a handmade wire ladder to descend 60 feet into the cave. For more than a decade, he couldn't convince many locals that there was much to Carlsbad Cavern.
