T+L: A New Tour of This Texas Cave Includes a Bridge Over Its Deepest Point and a ‘Natural Theater’ of Colorful Lights — See Inside

Travel and Leisure: A cave in Texas just underwent a major expansion, and is about to open to the public with an incredible new tour.

The Natural Bridge Caverns, which is located just outside San Antonio, completed an 1,100-foot-long expansion of public passageways, complete with a stainless-steel bridge across the cavern's deepest point and a new viewing area, according to the attraction. The expansion, which will open to the public on May 12, takes guests to areas previously only accessible by cavers.
