In 1930 the new William Penn Highway was built through the Appalachian mountains to connect Central Pennsylvania. They applied dynamite charges in a hill below Huntingdon, when a drill disappeared into a hole. They triggered the explosion anyway and the hillside collapsed. A big cave was found, which was decorated with stalactites and stalagmites.

Mr. Harry B. Stewart, the farmer who owned the hillside, decided to hire some of the highway workers to open the cave as a commercial attraction. Seven men worked 13 months to develop it. The Lobby Room, the entrance building, was built of steel beams supporting a wooden ceiling. In the cave the future path was marked by poking poles into soft sand and clay, Then sand and clay were removed.

Lincoln Caverns is said to have the largest variety of formations ever found in a Pennsylvania cave.

There is a nearby cave called Whisper Rocks which was opened up to the public in 1961. It is part of the Lincoln Caverns system, but a physical connection has yet to be found. Whisper Rocks has been very well protected and is almost as it was when it was discovered.
