Rock Hollow is a narrow, deep valley just north of the Meramec River. The park is known for its high quality flora and unique geological formations. Its steep rocky terrain provides many vistas, and scenic overlooks. The relief of the park is over 300 feet. Huge natural rock outcroppings, some 8 to 10 feet tall form walls at the higher elevations of the slopes. The Park consists of one major valley with the park boundaries going up of the surrounding hillsides. The ridge tops are in private ownership. Multiple side drainages feed into the main creek within the valley. The intermittent creek that runs the length of the tract shows evidence of large volumes of water flowing down the creek during times of precipitous events. Numerous seeps and small springs occur along the rocky slopes. The rocky outcroppings attest to the ruggedness of the hills. The rocky outcroppings harbor multiple species of ferns, mosses and lichens. Rock Hollow is known for its steep hills, rocky outcroppings and its showy display of spring wildflowers. During the spring months the valley is a hue of blue from Bluedeyed Marys and bluebells. Generally, mid to late April is the best display for the bluebells. Because of the various different habitats the park harbors many different species of spring wildflower which would include some of the following: shooting stars, green dragon, jack in the pulpit, glade onion, false onion, Solomons seal, birds foot violet, puccoon and a host of many other species. All of Rock Hollow Parksite consists of mature woodland. In the lower elevations of the valley large Ohio buckeyes, oaks, hickories, Kentucky coffee tree can be found. Drought resistant chinkapin oaks, blackjack oaks and other species can be found on the upland west and south slopes. White oaks dominate the east and share dominance with northern red oaks on the north facing slopes. The steep rocky west and south facing slopes, with numerous rock outcroppings house many of the same herbaceous plants that can be found on the savanna sites at Greensfelder. These same rocky areas harbor cedar glades similar to West Tyson. These long linear rock outcroppings occur along the same elevation and may be 4 to 8 feet in height with some reaching 12 feet. Some of the rock outcroppings consist of dolomite while others are made up of sandstone. Located in the north-west portion of the park along a steep south facing rocky slope are numerous lowbush blueberries. Revealed in the 1936 aerial photo the southern portion of the park was a small agriculture field. Open woodlands occurred along the old roadway on both the east and west sides of the road. The old roadway, Lawler Ford, can be seen on maps of the area dating back to the 1870s. The road was used to access a shallow area in which to cross the Meramec. A ferry also operated in the area to connect the north and south sides of the river. This operation apparently was not very profitable and was discontinued in a few years. In 1980 Bakewell Corporation purchased the property and subdivided it with the intent of developing the property. However the development never took place. One hundred and forty six acres of the original property was sold to the Parks Department in 1995. Bakewell Corporation continued to own the remaining 106 acres of land until it was purchased by the Great Rivers Greenway in 2003. Total Rock Hollow Parksite consists of 152 acres. Known for its zombies and bluebells the Rock Hollow Trail follows a narrow creek valley from the Meramec River up to the ridgetop. This 2.2 mile asphalt trail provides some stunning beauty. Each season brings something of interest to the trail user. The entire valley is heavily wooded. A small spring can be found about 40 yards behind the first bench. The spring outlet is at the base of a hill. The moist conditions make the spring pool and run a good habitat for mosses. The spring feeds the main creek but because of all of the creek rock in the main creek the spring water just disappears among the rock. It is still flowing but not on the surface. Some of the largest Ohio Buckeyes can be found just north of the first set of benches. Carrying buckeye seeds in ones pocket has been thought to bring good luck in folklore. However the seeds are toxic to humans and livestock if ingested. The buckeye is one of the first trees to lose its leaves in the fall of the year. Oh yeah! Zombies! It seems there have been some abnormal characteristics discovered by some paranormal groups that have been to the park in years past. Cold areas, mysterious shadows, strange lights all make for a good urban legend.

This is an easy paved trail with multiple side dirt trails. This trail connects to the Al Foster trail, the Rock Bluff Trail, the Zombie Trail and a few others. This trail is well shaded and multiple kinds of animals can be seen - including deer, squirrels and birds. Was a good walk. Not very crowded.

This is a very nice hike. There are many wildflowers, birds and even cacti to view but, stay on the trail. My wife got a lot of chigger bites when she ventured off.
