The Louisville Loop-in the east end, is not too far from me. And some sections are relatively flat while others have some hills. Paved, no motorized vehicles (other than the occasional e-bike). Fairly decent shade in most sections. The east end sections are 20 miles from one end of the park to the other. Eventually it is supposed to encircle Louisville and be a 100 mile loop. In heat such as is on us now, it can be a good diversion-no cars, decent scenery, and some shade are good ingredients for a ride on a hot day.
