It is very shaded (it is a wooded area) and thus helps against the heat. Some of the trail is paved, but not the majority. The total trail is around 2.7 miles, we walked about 2 miles worth of it.
The falls themselves
A spring house
A very nice walk/hike. A bit out of the way for visiting often, but both of my kids enjoyed exploring the area with me at the time. There are civil war earth works scattered throughout, so watch for those as well (they're not well marked). My favorite part (other than the walk itself) is the little spring house above.
