This photo was taken from the downward trail in the entrance to the Cavern, looking up. There are an estimated 3,000,000 Bats at times, and the flight covers a period of from two three hours. This wonderful sight led to the exploration of the Caverns by Jim White. From the middle of May to early October the Bats emerge each evening at dusk and fly off in a southeasterly direction nine times out of ten. Their return to the Caverns starts around midnight, and lasts until day break. The Bats stay in a remote part of the Caverns and are not seen on the regular trips through the Caverns. The temperature in the Caverns is 56 degrees summer and winter. The Caverns are open the year round |
