Mercer Caverns

Steep and tight. Goes down about 16 stories. Cave found in 1885 and tours started almost immediately with candlelight. Classic old school roadside cave tour. Free bumper sticker at the end if you complete the tour.

Air is so fresh in the cave! Very steep steps you must climb both up and down. Though not that long or intense of a tour, I would not recommend for the frail or easily winded. A fun little stop.
