Do you have an organization that would like to go caving?
The Aggie Speleological Society can set up a trip, provide gear and safely lead a group to a cave of your choosing. If you don't know of any caves, we can recommend one (mostly in the Austin area).
Caving is a great way to do something different outdoors and have a very unique experience. Your group will have a rare opportunity to get their hands (and clothes!) dirty as they explore a wild cave otherwise inaccessible to most people.
For more information, contact any of the current club officers.
