Watch 3 Million Bats Emerge From The Devil’s Sinkhole, A Little-Known Cave In Texas

When you think of bat caves in Texas, the Congress Avenue Bridge and Bracken Bat Cave probably come to mind first. There's another place in the Hill Country, however, with a bat colony that's over 3 million strong. Devil's Sinkhole State Natural Area is a little-known park with one of the largest bat colonies in Texas. You can watch them emerge from a 350-foot-deep cavern!

With a name like "Devil's Sinkhole," this is one Texas park you'd probably want to steer clear from - but that would be a mistake.

A little-known natural area located about 130 miles northwest of San Antonio, Devil's Sinkhole is home to one of Texas’ largest colonies of Mexican free-tailed bats.

The sinkhole is 320 feet wide and 350 feet deep, and it harbors approximately three million bats.

While visitors cannot enter the cavern - the person in this photo is a cave researcher - guided bat tours are offered during roosting season, which is late spring through early fall.

Every night, the bats emerge from the cave in search of food - and boy, do they feast! Scientists estimated the colony as a whole consumes 30 tons of beetles and moths daily.

Tours are given from May 1 through October 31, beginning at the park's Visitor Center and leading to a viewing platform over the sinkhole.

Wheelchair-accessible, the tour allows guests to peer into the sinkhole and watch as the bats fly out and blanket the sky in a swirling sea of blackness.

The tour fee is $14 for adults, $6 for children ages 4-12, and $11 for seniors 65 and up. Children under four are free. Morning tours are also offered on select days.
