The trail system in this park consists of several types suitable for all levels of biking and hiking.

Spring Valley Trail (3.75 miles), begins at the first parking lot near the entrance to the cave which the park is named. It begins with a water crossing followed by a steep and rocky climb to the top of the hill. From here the Spring Valley Trail consists of 2 loops, an outer loop which is the Spring Valley Trail and an Inner Loop Trail contained within.

Both loops are tied together via 3 short connector trails offering a wide variety of riding options. The loops vary from tight and twisty to open and flowing as they weave in and out of the many sinkholes in the area. Both loops are mostly packed dirt, while not technical, the trail design offers riding that is suitable for beginner as well as advanced riders.

The Bluff Trail (1.2 mile loop) is accessed via a climb up the park entrance road. Turn onto the trail at the end of the guardrail on the right. Bluff Trail offers the best technical features for the experienced rider. Several challenging rock gardens present themselves and the climb to the top is rewarded with a beautiful view of the Mississippi River Valley. In the winter months keep an eye out for Bald Eagles.

The Mississippi River Trail (5 miles) consists of two loop trails that are paved, and provides a perfect place for riding with the entire family.  The trail is located in the flood plain wetland area and is mostly flat; it offers views of the bluffs above as well as the Mississippi River. The paved trails also provide an enjoyable place to ride when the natural trails are too wet for use.

The park occupies 525 acres that include a flood plain wetland area, heavily wooded forest with a variety of old growth trees such as the Shag Bark Hickory, a picnic shelter and scenic river overlook. This area is geologically known as a Karst Plain- an area consisting of caves, sinkholes and springs formed from the dissolution of layers of bedrock. The many sinkholes provide a haven for a variety of wildlife including wild turkey, fox, rabbits, squirrel, deer and raccoon.

The trails are open to equestrians, hikers and mountain bikes. Please observe proper trail etiquette when using these trails.


Cliff Cave Park is located on the banks of the Mississippi River in South St. Louis County. Take I-255 to Telegraph road. Go south on Telegraph 1.7 miles to Cliff Cave road. Go left on Cliff Cave road and continue approx. 1 mile into park.


There are composting toilets, and water available at the pavilion overlooking the river.

Park History

Cliff Cave is a historic and archaeological site. The cave is also known as “Indian Cave” and developed in Mississippian St. Louis limestone. With 4723 ft (1514 m) of cave passage surveyed, it is the second longest cave in St. Louis County.  In October of 2009 the cave was gated to protect a population of endagered Indiana Bats which live in the cave.
