A mix of gravel, asphalt and dirt trails. My biggest complaint is that my shoes got soaking wet during an unavoidable creek crossing. Generally I stray away from blisters. Nice stretch through the woods but pretty crowded and I ended up crossing roads in a neighborhood. Some pretty areas but not well marked and not what I expected.
Jemison Park is located on a flood plain in Mt. Brook-Birmingham, an expensive section of the city. The path is half paved and half crushed gravel and offers an easy 'walk through the park.' The path is near a main neighborhood road and cars can be heard going by. Even though road noise is heard, about half the trail has HUGE Loblolly Pines five to eight feet in circumfrence. I was amazed at the sheer number and size of the pines. It is rare to see so many in one location. A creek runs the entire path length and is clean. There is one footpath cross over that the hiker has to 'step' on concrete steps to make it across.
The tree canopy keeps the entire path shaded and the benches along the way allow for a rest and reflection. The only drawback is during the hot periods of summer there is no breeze in some sections and it gets as hot as an Asian jungle. But just keeping walking and it gets cooler. Bikes can be ridden, but the concrete path is narrow for bikers and walkers together.
