Terry Keefe Falls is a really great waterfall that is a short hike off of Falling Water Road - or as a spur trail off of the Ozark Highlands Trail.
To get there, take the turn on Falling Water Falls Road as described here.
After turning on Falling Water Falls Road, take the road 5.3 miles to the bridge crossing across Falling Water Creek. Continue on this road for another 1 mile to a spot where a creek comes in from the right and flows under the road. This is about 2.8 miles from the Richland Creek Campgroudn if you're coming from that direction. Park where you can here.
The trail starts off on your right and heads up into the woods. It's a well-worn trail and pretty easy to find (there was also pink tape marking the spot). The trail goes up the hill with the creek to your right. The creek here has a lot of large rocks and water features. Before you get to the top of the hill, you'll cross the Ozark Highlands Trail. This is at the 141 mile point of the OHT.
Continue straight at the intersection up the hill. The trail is marked with white circles painted on the trees (not to be confused with actual white blazes that mark the OHT). The trail will go back down the hill and bend to the right, and then back up a hill. As you cross this hill you'll begin to see an amazing bluffline on your left.
The trail will then bend to the left and follow a creek bed and then proceed to cross the creek bed multiple times on the way back to the falls. The creek is mostly dry here, so it's easy crossing.
A little ways up the dry creekbed and you'll get to a huge rock hollow and Terry Keefe Falls in the middle of this hollow.
Terry Keefe Falls is 78 feet tall and had a nice flow to it while we were there. It's definitely one of the taller falls in the area.
Distance: 1 mile round trip
Footwear: Trail shoes or tennis shoes would be fine.
