Fun dirty activity, bring your own shovels and rakes and wagon, don’t wear white pants like I did. You may also want to wear rubber boots, rubber gloves and some clothes you’re comfortable with getting dirty. The diamonds are hard to find, I have found the volcanic rocks and jasper that I’m very happy with. You may also enjoy cleaning your car rugs after visiting this park, or have extra shoes to change. Otherwise, it was interesting and unusual activity, I liked it.
