"BIG ROOM SELF GUIDED TOUR" Top 5 Page for this destination Carlsbad Things to Do Tip by Sharrie

BIG ROOM SELF GUIDED TOUR: Tour the 14 acre chamber of gigantic formations with a roof of almost 200+ feet above ground! A well-paved 1 mile stroll took us about 2 hours or so to complete. One has a choice of descending over 750 feet through the Natural Entrance Route on feet which will take about 1 hour of strenuous walk on steep trail or take the elevator to the Underground Lunch Room & continue to the Big Room from there. For those with limited time to explore the caverns, take the elevator like we did.

The Big Room:
* Largest natural limestone chamber in the U.S.
* Length = 4000 feet.
* Width = 625 feet.
* Greatest Ceiling Height = 255 feet.
* Area = 57 acres.

Directions: 750 feet below ground.
