UT Grotto

The Underground Texas Grotto (UTG) is an Austin-based 501(c)(3) non-profit. Our members explore, restore and conserve caves, 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 seventy years. Members range from total beginners to international expedition cavers. We offer training, meetings, trips, parties, and on-going restoration projects. We also participate with fellow organizations to support local conservation efforts. The Underground Texas Grotto is proud to further cave education in and around Austin.

meeting information

We meet twice monthly on 1st and 3rd Wednesdays. The first meeting of the month is a formal meeting, held in-person at a rotation of venues. Details are available on our email list, calendar, and Facebook page. Formal meetings feature presentations by guest speakers, trip reports of recent caving, announcements about upcoming trips and practices, and a chance to mingle afterward. Informal meetings are all about getting to know the grotto. We meet at The Posse bar and restaurant, honoring a long-time grotto tradition, to discuss all things cave related.
