Welcome to the Grotto

The Underground Texas Grotto (UTG) is an Austin-based non-profit that explores caves in Central Texas and beyond, keeping alive traditions from 1951. We are the oldest caving organization in Texas and have served as the nexus for cave exploration all over Texas and Mexico for more than fifty years. Members range from total beginners to international expedition cavers. Any central Texan interested in caves is welcome. Learn about our meetings below.

Formal meetings feature presentations by guest speakers, trip reports of recent caving, announcements about upcoming trips and practices, and a chance to mingle afterward.
