Greer Spring is the second largest spring in Missouri. Its average daily flow of 222 million gallons more than doubles the size of the Eleven Point National Scenic River into which it flows. The spring flows from two outlets about 250 feet apart at the bottom of a steep, shaded ravine at the terminus of the trail. The spring run drops 62 feet in elevation for 1.25 miles where it runs into the Eleven Point National Scenic River.
The area around the spring is misty all year long and has a lush growth of many types of ferns, mosses and liverworts. Common hydrangea, Bishop’s cap, wild columbine, and Ebony spleenwort are some of the plants that can be found growing on the dolomite cliffs surrounding Greer Spring.
