Mississippi Greenway: Cliff Cave Park

The Mississippi Greenway trail in Cliff Cave Park is a 4.6-mile paved, loop asphalt trail that circles the floodplain bottomland. Outdoor enthusiasts can walk, run or ride along the trail and enjoy scenic views of the Mississippi River.

There are two other unpaved trails that connect with this section of greenway - the flat, one-mile River Bluff Trail, which offers an outstanding view of the river and surrounding valley from atop the bluff; and the three-mile, moderately hilly Spring Valley Trail. All three trails lie within Cliff Cave Park.

Recreational Opportunities

Cliff Cave Park in the Mississippi Greenway offers stunning views of the Mississippi atop rocky bluffs that tower 170 feet over the river. It lies within one of the most naturally diverse plant and animal communities in the region, offering rocky, droughty hillsides, as well as woodlands and wetlands.

This unique park within the greenway gets its name from the cave tucked in the bluffs of south St. Louis County. There is tremendous folklore surrounding the area, including stories from its past as a riverside tavern during the early exploration days of Missouri, a hideout for horse thieves as well a summer camping area for native Americans. It is known for its Karst topography – a region where the bedrock has been dissolved or collapsed, leading to caves or sinkholes.

The park offers hiking, mountain biking and equestrian trails, as well as picnic areas, grills and shelters. After a snowstorm, this area is perfect for cross country skiing. This area attracts hundreds of migratory birds in the spring and fall. In the summer, Great Blue Herons and Egrets can be seen, and some bottomland woodlands and wetlands can be found along the greenway.
