My boyfriend and I came in a long day and had a solo tour with the owner. The staff are *very* knowledgeable and friendly. The history is as interesting as the gorgeous cave. From the gift shop to cave exploration, to gem mining, we had a wonderful and unforgettable day. After I expressed interest in rocks and minerals, the owner actually gave me a lot of information about the rocks in and around the cave. Since I am a rock lover, he even gave me a small piece of mineral for free as a souvenir! We love all the items in the gift shop, it is difficult to control the purchase of all items by ourselves! The neatest place ever and great staff. We like it!
