Plan the visit
The place
Devil's Sinkhole is not a conventional state park. The centerpiece is a massive vertical cavern opening that shelters a seasonal colony of Mexican free-tailed bats, and protecting that habitat shapes how visitors experience the site.
Evening bat tours can culminate in thousands of bats spiraling from the sinkhole to feed after sunset. The spectacle varies with season, weather and the colony's behavior, so no wildlife viewing is guaranteed.
Plan this destination around an official reservation rather than simply navigating to the gate. Follow tour instructions closely and confirm meeting locations and seasonal schedules before making the drive.
