From what we were able to see, Mannis Branch Falls is quite scenic. Unfortunately when we went to see the waterfall (in the late Spring, early Summer) it was mostly hidden behind the trees. In our photos you really can only see the bottom of the waterfall. The top part is almost completely blocked from view.
It looks to be between 25-35 feet in height and flows into Little River inside the Great Smoky Mountains National Park. The waterfall was rated for the time of our visit and does not reflect other seasons not yet viewed at this waterfall.
To get to Mannis Branch Falls, head toward Elkmont Campground. Just a short distance away there will be a paved pulloff for you to park at. Follow the roadside. Watch for cars as they don’t always leave a lot of space from the edge of the road and are quite close. Look for a fisherman’s trail about 50 yards away from the parking area and make your way down the trail to Little River.
Across Little River you should see Mannis Branch Falls. Do NOT wade into the water or try to cross Little River. There is a strong current here and it is extremely dangerous.
If you hope to get a good view of this waterfall I would recommend the end of Fall after the leaves have changed and started to fall off the surrounding trees or in the Winter when all the leaves have fallen. This way hopefully there will be a better view of the waterfall which will not be blocked by the foliage.
Its not that hard crossing the river, its only maybe 24″ deep. Its well worth the effort to sse it
