The Mexican free-tailed bats living under the Congress Avenue Bridge are renowned as the world’s largest urban bat colony. But their cousins in the Hill Country are no slouches either.
New tours are beginning at the Bracken Bat Cave, on the outskirts of San Antonio at the Natural Bridge Caverns, where participants can witness the evening exodus of bats from what’s called the world’s largest summer bat colony -- period.
Unlike the bat watching along Lady Bird Lake, the tours aren’t free: they costs $25. But they're being held in conjunction with Bat Conservation International, an Austin-based group dedicated to preserving bats and their habitat.
