3 Creeks Conservation area has several trail loop variations. There are various trails heads by the parking area, and beyond the gate down the access road. Some of the loops are short runs, while the outer loop is 8 miles. At various points in your ride you will be able to switch to other loops. Three Creeks trail is for the beginner to intermediate level riders. The hills are short and sweet with some pretty decent downhill runs. There are some fast, flowy sections along the river that you will enjoy. I recommend that you ride this trail a couple of times to find your favorite route. Enjoy.
From Columbia Missouri at the Highway 63 and Interstate 70 Junction. Head South on Highway US 63 for 7.7 miles. Turn right on E. Deer Park RD. (E. HWY AB). You will be on a gravel Road For about 2.4 miles, until you come to the Three Creeks Conservation sign. The gravel road will have some sharp turns so be prepared, and drive slowly.
