- Raise funds to Stop 3009 Vulcan Quarry!
Experience one of the great wonders of the natural world: the spiraling emergence of over 15 million Mexican free-tailed bats—the largest bat colony on the planet—as they begin their evening hunt.

Proceeds from this fundraiser will support the ongoing battle against the 1,500-acre open-pit mine and quarry planned by Vulcan Materials between Bulverde and New Braunfels—just four miles north of Bracken Cave. Bat Conservation International will also receive a small portion of the proceeds.
Tickets are $55 per person (plus fees). Directions and additional event details will be forwarded following ticket purchase.
Hors d’oeuvres, beer, and wine begin at 6:30 p.m. Bats emerge at approximately 8:00 p.m.
Thank you to our sponsors who have graciously donated appetizers and locally grown and brewed flavors of the Hill Country: Oak Valley Vineyards, Dry Comal Creek Vineyards, Guadalupe Brewing Company, and Freetail Brewing Company.
Please join us for an exciting evening you won’t soon forget!
