The Taylorsville reserve has a set of concentric oval trails that range in length from .8 miles to 4 miles, the orange trail.  The oragne trail loop starts at two different trail heads along st. rte 40, on the eastern side of the taylorsville dam.  The eastern length of the trail runs north/south through the edge of the reserve.  Don't be fooled by the layout of the local trail map, this is far from an easy section of trail.  With continuous, and at times steep, elevation changes this section of trail is pretty strenuous.  As you pass through the last of steep grades the trail levels off a bit and pass through a pine/cedar grove with a nice look out point at the northern tip of the trail.  Along your way back the lower portion of the trail runs along the Great Miami river with plenty of spots to stop and enjoy the senery.  About half way back along the lower portion of the trail is a set of switch backs that are pretty tough when it's dry, and down right dangerous when it's wet.  After you get through the switch backs you have hike straight up hill, with the aide of a few steps and a well kept gravel trail the trail then continues back down and along the river until you complete the loop with one last long up hill hike.
