Rock Bridge Memorial State Park
A sinkhole-and-cave landscape with a natural rock bridge, underground stream, restored grassland, and routes from boardwalk strolls to wild-area hikes.
Artwork inspired by Frederick Oakes Sylvester
The park protects one of Missouri’s most accessible demonstrations of karst: sinkholes, springs, caves, an underground stream, and the 125-foot natural tunnel called Rock Bridge. Devil’s Icebox Boardwalk is the concise introduction; Gans Creek offers longer, quieter terrain.
Connor’s Cave can sometimes be explored near its lighted opening, while Devil’s Icebox Cave is closed to protect bats. Conditions, water, mud, and wildlife protection rules matter, so “cave park” does not mean unrestricted underground access.

Four deliberate moves through Rock Bridge Memorial State Park
- Boardwalk
- Start with Rock Bridge and the spring.
- Cave
- Enter only where and when explicitly permitted.
- Wild area
- Carry a map and allow more time than mileage suggests.
- Water
- Stay out during flooding and storms.
Good to know
The “rock bridge” is a remnant of cave roof; seeing water disappear and reappear nearby makes the underground plumbing easier to understand.
