Crater of Diamonds in Arkansas is one of the only places in the world where you can prospect for real diamonds. The state park is a one-of-a-kind experience. Visitors to the park search a 37-acre plowed field, the eroded surface of a volcanic crater, for variety of rocks, minerals, and gemstones – and any rock or mineral you find is yours to keep. Even though I have never found a diamond there every time I have been there other people have. It’s a great time and if you are a camper it has a very nice campground. You can also stay in town or a little further away stay nearby at state park lodges.
