The Brandywine Falls Loop Trail in Cuyahoga Valley National Park, OH, is one of the best hiking trails in the park at 1.4 miles long.
This trail leads you down to the middle of Brandywine Falls -- this spur trail section is missing from this data; however, follow signs for the falls, you can't miss it.
After the falls, the loop trail brings you down to the creek and back to the lot. You will have to cross the creek and when I was visiting, the bridge was down, so you had to cross at your own risk. At the time, the creek was low and easy to cross mid-summer.
