Meramec Caverns

Iconic St. LouisRecreation Facilities

About

Uncover Missouri’s buried treasure beneath the rolling hills of the Meramec Valley. Meramec Caverns, the largest commercial cave in the state and one of the most awe-inspiring caves on the planet, boasts astounding formations, including glistening stalactites, magnificent stalagmites, an ancient “wine table” and a seven-story “mansion,” which were formed from the erosion of large limestone deposits over millions of years. Trained rangers guide captivating tours along well-lit walkways to some of the rarest and largest cave formations in the world – they’ll also show you where an episode of Lassie was filmed in 1966. The underground oasis is a cool 60 degrees year-round, and you can supplement the spectacular experience with ziplining or a scenic excursion on the Meramec River aboard a canopy-topped riverboat. Guided walking tours depart every 20 to 30 minutes beginning at 9 a.m. The cavern tour takes one hour and 20 minutes, covering 1.25 miles.
