Cave Tours in Leasburg, Missouri
With more than 6,000 recorded caves, Missouri rightly earned its “Cave State” nickname. In Leasburg, Missouri, the Onondaga Friends Association hosts nighttime flashlight-only tours of the Cathedral Cave at the Onondaga Cave State Park. After a short ⅓-mile hike in the dark down the Deer Run Trail, you’ll enter the Cathedral Cave entrance located along the Meramec River. Hollowed in ancient Gasconade dolomite, the 15,639-feet-long cave has multiple side passages, slump pits, and a natural bridge. Bats, salamanders, spiders, and frogs hide in the nooks and crannies of imposing stalagmites, dramatic stalactites, striking draperies, and impressive flowstones. The cave’s cool 57-degree climate is a welcome respite to Missouri’s humid summers.
