Mammoth Cave

If your schedule allows you to be in the vicinity of Mammoth Cave National Park on August 25th, you'll be able to go on one of the cave tour's for free in celebration of the 91st birthday of the National Park Service.

In a bid to make the "Snowball Room" more accessible to park visitors, Mammoth Cave officials are testing a new route to the room located 267 feet underground. Instead of having to endure a 4-mile walk via the Grand Avenue Tour, this route involves a mile-long walk along mostly level ground.

Rainfall at Mammoth Cave National Park this year has been so low -- 10 inches below normal since the start of the year -- that the Green River is too low for the Green River Ferry and Houchins Ferry to operate.
