Underground Texas Grotto

The Underground Texas Grotto (UTG) is a 501(c)(3) non-profit from the Austin area that explore caves in Central Texas and beyond, keeping alive traditions from 1951. Members range from raw beginners and occasional cavers to hard core international expedition cavers. All community members interested in caves and caving are welcome.


Our meetings allow for hybrid attendance in person or via Zoom. Events, trips, and meeting links are posted on our facebook page.
