Very easy hike (and I'm not an experienced hiker at all). Really glad I had time to kill and saw the sign.

I used to live about 45 minutes away from Natural Tunnel. If you are looking for places to stop for the night, the campground is very nice, has some of the cleanest bathrooms/showers I've ever seen at state campgrounds, accommodates both tent and RV campers, and includes passes to the on-site swimming pool (with decent slides for the young and young at heart). There are also hiking trails.

For those less inclined to hike down the steep but relatively short trail to the natural tunnel, there's a lift. You can pay a little for one round trip or about twice that for an all-day pass(It's fun enough to pass as an amusement park ride for many kids).

The railroad is still operational. I was fortunate to see a train pass through the natural tunnel at my visit.

Natural Tunnel State Park

Natural Tunnel, was called the Eighth Wonder of the World by William Jennings Bryan, and today is the focal point of Natural Tunnel State Park. The million year old tunnel was created as groundwater ate through limestone and dolomite via crevices, and later as a creek diverted underground and carved the large passage.

You can't walk through the tunnel -- trains run through it -- but the Park has an overlook where you can admire this formidable water-eaten hole. Sept. 2013: Photo added.
