angelina marottaWas great priced!!! Had an amazing time!! Found some cool pieces and got rings made! It's great for all ages but I would say real young ones might have trouble with the rock braking. Other then that, I would definitely go again!

carolann herbstWhat a great place to bring your family. There was a husband and wife and he said he was there for 50 days mining and his wife would come on the weekends.. The knowledge that that that couple had was mind blowing. They both took your time to explain it to my family and myself what we needed to look for in the proper way to dig. Overall, our experience there was wonderful. I have a 16-year-old boy that said he didn’t wanna go cause it looks stupid really got into it and he really enjoyed the knowledge of that couple gave to us and it’s just the act of kindness that those two didn’t have to share, but did and now My Son is wanting to go back for a full day Thank you for such a great time

Inga RozinWhat an amazing experience! Searching for Herkimer diamonds was so much fun, and finding your own crystals is incredibly rewarding. The staff were friendly, everything was well organized, and the whole experience was unforgettable. We can't wait to come back for another adventure!

Atalanta ProductionsWe prepared as much aa possible with protective gear, hats, gloves, sun blocking clothes, goggles etc and it was a great experience (first time) - we didn’t set any huge expectations as to what we would find, but sure enough ended up finding real crystals/Herkimers to take home! The gift shops and campground - as well as area restaurants - are very nice, clean, and we want to make another trip here soon!
