Crystal Grove Diamond Mine & Campground

5 ReviewsAdd Review

Diamond mining enthusiasts can dig for Herkimer quartz crystals at this wooded campground that combines overnight stays with hands-on mineral collecting. Crystal Grove Diamond Mine & Campground operates its own mining area within walking distance of the campsites, accessible by a bridge over the stream that runs through the property.

The campground accommodates RVs up to 40 feet with electric and water hookups, plus a dump station for convenience. Sites along the creek provide the sound of flowing water, while the wooded setting offers natural shade once trees fully leaf out in late spring. Hot showers and restrooms receive regular cleaning, and a small on-site store stocks basic supplies. A pavilion serves groups or provides shelter during rain.

Campers report the setting stays relatively quiet, with good biking terrain for kids throughout the property. Kerry H. notes "Clean bathrooms, hot showers, diamond mines a short walk from camping." Bug spray proves useful during warmer months. The mining activity requires a separate fee beyond camping costs.

For those exploring the broader region, the campground provides access to places to camp around St. Johnsville. Firewood sells at competitive prices compared to local stores, with larger quantities than typical kiln-dried bundles. The season runs April through October, with reservations available and pets welcome.

Quiet campground

We enjoyed our weekend here. Our site was next to the creek and relaxed to the quiet sound of water flowing by. Purchased firewood that was quite competitive in price compared to local grocery/convenience stores that sell kiln dried wood here in NYS. I’d say about double the amount of wood. Being in May the trees had not fully gotten their leaves so there was a bit more sunshine. I’d imagine in a month or so it will seem more wooded.

All about the Herkimer Diamonds here

A fine campground with it's own Herkimer Diamond Mine walking distance (or you can drive up your vehicle) to the mining area. A fairly small, nicely wooded campground. A bit dated in the free shower/toilet buildings but the staff kept them very clean and stocked. There is a pavilion for group or rainy day activity. Staff is extremely friendly and informative about the mining (extra charge).

Nestled in the woods, a creek and Herkimer Diamonds!

Looking for adventure this is a place to find it. Along with staying at this peaceful wooded campground, one can “mine” Herkimer Diamond quartz crystals adjacent to the campground via a bridge over the stream.

I enjoyed a site next to the stream. The store is small but had what you may need. The grandchildren had a great time and love looking and finding Herkimer Diamonds.
