Opal Trail

At the end of this trail are two famous opal mines, Nowak's Opal Mine and Barnett's Opals. The very light colored terrain in this canyon consists of volcanic ash. It has yielded many opals over the years. This area used to be BLM land. Back in the day, Barnett's Opals charged $2 a head for a day pass to mine. Currently, rock collecting is not allowed here. Since it is now state property, please check with the State Parks Department before rock hounding within the park as the rules are often subject to change. This is a geologically sensitive area. Please keep your vehicle on the trails and enjoy your stay.
