With its steep shale cliffs, the Rocky River Reservation contains some of the Emerald Necklace's best vistas. But walkers craving a peaceful stroll find that noisy traffic on Valley Parkway never shuts up, cyclists hog the all-purpose trail, and the Nature Center is often overcrowded. So make your way to Morley Ford Loop Trail, a half-mile loop roughly four miles south of the Detroit Avenue entrance. This spot is often overlooked -- but that's the point. The clandestine, overgrown trail hugs the river while letting you take in those towering cliffs. Best of all, thick brush eats up the street sounds, leaving only the serenity of water trickling over jagged stone and the seclusion your body sometimes craves.
