Since the 1890s, people have flocked to White Cliffs in the hope of finding their fortune. With Red Earth, you can go more than 13.5m beneath the ground into a working opal mine within the historic diggings. See how miners are still searching for these glittering gems using modern equipment. You’ll even have a chance to dig at the mine face yourself and may be lucky enough to discover a piece of opal. Tours depart from the Red Earth Opal Gallery and Coffee House at 3pm.
