Okay, so there is a $7 entry fee and I disney personally find any diamonds, however the Crater of Diamonds State Park is still pretty cool. It is the only diamond-producing site in the world open to the public and is located in Murfreesboro, Arkansas . The park is owned by the state and is open as a tourist attraction for the state, which is pretty cool. You can also camp, go to a water park or go to the information centre.
Essentially, you pay your entry fee and then watch a short video about how to find diamonds. You can rent equipment to Mae the job easier, or just walk around and look on the ground. The diamond finds are likely to be small, if you find any. However, you can find a range of other minerals, or just cool rocks.
I didn’t find anything valuable, but I did find lots of rocks that will make cool jewellery when I get home.
