Our spacious, wooded campground is right next to our own “Herkimer Diamond” mines.   We invite you to enjoy a natural campground setting with modern conveniences.  Spend the day collecting beautiful “Herkimer Diamonds” and then stroll across the footbridge back to your campsite for a leisurely dinner.  Whether you are a tenter, an RVer, or would prefer to stay in a comfortable cabin, we have a space for you.  Or just come for the day to visit our three collecting areas.

The mines and campground are open daily from mid-April through mid-October.  The camp store sells ice, firewood, camping basics, mining tools, gift items, and beautiful mineral specimens from around the world, as well as an extensive assortment of our own “Herkimer Diamond” crystals and matrix specimens.

While you’re here, enjoy the many attractions of central New York and the nearby Adirondack State Park.  This area is rich with historical sites, beautiful birds and wildflowers,   outdoor activities, and natural wonders; there is sure to be something for everyone.

We stayed here and it was wonderful! So clean, bathrooms are clean, even fully rented it wasn't overcrowded or loud. We had a beautiful stream running right behind our tent too! The staff was friendly and helpful, mining was fun and we have lots of nice stones to bring home. I highly recommend it!!

I absolutely love Crystal Grove. Last year, my girlfriend and I visited to mine for a day, this time we mined, camped the night, and mined again the next day. The staff here is super-friendly and very helpful. They remembered us from last year and greeted us as if they'd known us for years. Tool rental is easy and quick. Even if you break it, they'll take it back and return your deposit. They offer firewood and ice after-hours on the "honor system" - drop the money or square-up in the morning, which is really handy. As far as the camping grounds, we really enjoyed how nice they were - just the right amount of privacy in the woods. We were assigned one space and fell in love with the neighboring one and they changed our reservation with a smile. We ended up staying in the "primitive tenting" (no hook-ups), which goes back to the creek, and we set up our tent creekside. The ambiance and privacy were worth way more than the small amount we spent to camp. 20/10 - Absolutely would recommend this place time and again.

We had such a great time! My bf first time and he is hooked!! Can't wait to go back!! The couple that run the place are very nice and so laid back, If you want to experience mining I suggest Crystal Grove. We camped by the creek it was beautiful :) Thanks Crystal Grove!!!!

Campground was neat, clean and well maintained. Staff was friendly and knowledgeable. New owners were friendly and talked about the changes under their management and future plans. Camp sites were large and shady. Mines were open and active for campers or day use. We explored 3 campgrounds in the area to find a place to camp and after checking them all out, returned to Chrystal Grove for a true camping experience. Cannot wait for our weekend at camp!
