WATERLOO — Illinois Caverns reopened to the public Wednesday after being closed for 10 years.

Located south of Waterloo, Illinois Caverns was closed in 2010 as a precaution against the spread of White-nose Syndrome, a fatal disease that affects certain types of bats.

"We certainly didn't like to see the site closed, but the closure did allow us to complete some necessary work to ensure the safety and enjoyment of our visitors once we reopen," said Von Bandy, director, Office of Land Management for the Illinois Department of Natural Resources.

Illinois Caverns will be open seasonally from April through October. Weekly, the site will be open Wednesday through Sunday from 9 a.m. to 4 p.m.

"There is no other site like this in the entire state of Illinois. It is right here," said Colleen Callahan, director of the Department of Natural Resources. "As I went through I kept saying how fun this will be for kids, and I felt like a kid. It's a whole other experience to actually see it and feel it in person."

Cave explorer Joe Light, president of Meramec Valley Grotto, one of the largest cave exploration clubs in the Midwest, is excited that the cave is reopening.

"Illinois Caverns has been a treasure enjoyed by generations of residents," stated Light. "The cave also provides an excellent adventure for youth groups, Boy Scout troops, and numerous other visitors and may inspire the youth of Illinois to pursue the study of biology, geology, and other sciences."

Danny Trevathan's spot as the leader on the field of the Chicago Bears defense is challenged by those who think he might be too old now but at 31 is he really much older than some of the best linebackers in the NFL?

Visitors will be required to have the mandatory safety equipment, fill out a permit, and pass a gear inspection before entry. Groups of 25 or more must preregister.

The cave has been left in its natural state, said Mic Middleton, site superintendent of Illinois Caverns. "It is not like a Meramec Caverns or Ruby Falls, those famous caves. It is a natural cave with natural landscape. The steps, just going down are steep, is just not for everybody to do it. Safety is the main thing and we want to stress that."
