Formation at Stark Caverns seen in black light

Stark Caverns is now offering a new cave experience – a Black Light Tour, unique in the Lake Area and one of just a handful in the country. This tour is completely different than our standard tour and focuses on the science and beauty of fluorescent minerals. It’s unlike anything you’ve seen or done before.

You’ll enter the completely dark cave outfitted with a helmet (it’s harder to see those low hanging rocks in the dark), safety glasses (to help protect your eyes from the UV light), and a black light flashlight. Your tour guide will have been trained on fluorescent minerals and of course will know the most spectacular areas of the cave to see in black light.

When you walk in and turn on your flashlight, you’ll feel like you’ve entered another world, awash in purples, pinks and white. Formations that are not normally visible in our standard tour pop out in the black light where there are increased concentrations of calcite.

You’ll also be treated to our growing collection of fluorescent minerals from around the world.

Advance tickets are required with tours offered Tuesday evenings at 5:00 through May and 6:00 during June, July and August.  Call 573-369-3306 to reserve your spot today. We also accept advance reservations for groups of 8 to 15 people if another evening is preferred and other events aren’t scheduled.
