My cousin & I had fun exploring the South Chagrin Reservation. There's a great link at the bottom to some waterfall hikes. We didn't have time to check them all out.
Sulfur Springs area
Henry Church area
I think this is Double Decker Falls - park at Henry Church Rock

Squaw falls - just a trickle when I was there

Zen Falls - no water
Quarry Rock Picnic area
Chagrin Falls
