Hemmed-In-Hollow Falls, the highest waterfall in Mid-America, is a spectacular piece of nature in the Buffalo National River area. This is considered a complicated area to access.

I do have to say the hike was beautiful, although it was a bit long, steep and hard. Once there, the hollow is in a valley closed in on three sides by 200 foot bluffs, the waterfall is 209 feet high. It took us 5 hours 15 minutes to get in and then back out. The 1200 foot climb down was a little more tricky because of the rain that had made it pretty slick. Coming back it had dried some and was much easier for all of us.
We didn't know it at the time and wouldn't have had the time or strength but on the same bluff line is Diamond Falls, the second tallest in the state at 148 feet. Maybe another day-
