Date: October 25, 2011

November 6, 2011 is the last day of cave tours for the 2011 season. The visitor center will remain open and park rangers will offer guided activities on the surface each Friday, Saturday, and Sunday through the end of November.The visitor center and activities will be available 10am to 4pm on these days. 

It gets cold up here in the mountains in early November - just ask a bat.With the first freezing weather bats seek out warm shelter to hibernate for the winter.If disturbed early in the season, however, they will fly back out into the frigid cold.

During this period of otherwise slow visitation, the caves will close to protect the bats.Early records indicate the cave was once a hibernation shelter for hundreds if not thousands of bats in the winter, and perhaps it will be again.

Up here in the mountains the adventures available to humans never end, however. Trails are open year round for you to explore. A friendly reminder though: chains or traction tires are required on Highway 46, and we do get snow! Safety first! And, have fun as you explore and enjoy your National Monument.

The cave tour season will begin again next year on March 24th, 2012.
