The Mine


Come prepared for outdoor activity, rain or shine. Wear old clothes, shoes suitable for climbing over rocks and walking in mud, gloves, hats, safety glasses, collecting containers, sun block or rain ponchos. Bring your own hammers, chisels & small garden tools if you have them. However, we do sell or rent prospector's tools.

Mining for Herkimer Diamonds is an outdoor activity enjoyed by people of all ages. Prospector tools are available for rent or for sale. They are desirable, but much can be accomplished with small hammers and garden tools. Visitors should come in clothing suitable for digging in the earth. For the more serious mineral collectors we also offer guided mineral collecting.

If you like, bring your lunch and rest in our picnic area. The Rock Shop keeps cold soda, ice cream, candy, etc., for a quick snack.

Our season starts April 1st and ends October 31st.
Campsites are available right where you dig.
Visitors may prospect daily from 9:00 a.m. to 5:00 p.m.
Your ticket entitles you to enter and leave the digging area as many times as you like. Within walking distance you will find a luncheonette, grocery stores, post office, trout fishing and much more. Plan to stay all day.

The crystals have been waiting 400 million years for you to find them. Diggers take home all the diamonds and rock specimens they find.

Mining Fees: age 7 and under $5.00, age 8 and older $10.00 per day.
