A great diversion if you are in the Hershey area. The caverns are beautiful and our tour guide was witty and knowledgeable. He still seemed to enjoy his job even though I am sure he had gone into the caverns thousands of times. The caverns are fascinating and give you a great appreciation for how the earth's geologic forces work. Also try the Gem Mill Junction right outside of the gift shop. You buy a bag of sand and sift through it in a water filled trough. Your kids will think they are truly prospectors looking for diamonds and rare gems. It is good fun.
