  • First time going for Herkimer diamonds here, awesome experience. Staff in the office were forward and helpful with where to go and what to do to find treasures. Entry fee very reasonable and tool rentals available for nominal charge ($1 for a hammer, etc). Availability of multiple different ways to mine, open pit, rock breaking, mini g from the rock face, sluicing, lots of fun, kept the kids (7 and 5 years old) active and happy for hours and they allow you to keep all you find. Awesome experience, will be back again.
  • We tried both mines and had A LOT more luck here. They have a sluice set up that allows you to process quickly find specimens and my kids loved it!
  • First time being here was a pleasant experience. The lady at the desk was helpful and friendly. Found some cool sparkles
  • Easy pickings. Great price.. Family owned
  • Great way to spend the day.
