What campers say
Ace of Diamonds Mine & Campground offers a hands-on Herkimer diamond experience with basic camping across multiple levels that provide good star views. Visitors note friendly, helpful staff, a welcoming community vibe, rentable tools and both sluice and hammer mining methods, plus on-site amenities such as showers, restrooms, and lean-to units. Success varies — finds are more common when fresh rock is being added, and results dip when there’s no active replenishment. Tool rental and entry fees are generally reasonable to fair, though bringing your own tools can save money. Cell service can be weak on lower levels.
