My husband and I hiked this trail together. We are in our 50s and overweight but we managed to make it. Some parts were difficult but we survived and enjoyed it. We had no problem staying on the trail. We just followed the paint markings on the trees.
This trail is obscured in many areas due to trees down from lingering tornado damage, and the trail junctions are unclear, resulting in my following animal trails accidentally instead of the real trail. I took 2 dogs, and while we completed the loop around the island, we weren't on the trail for about 70% of the hike, it wasn't without a fair amount of difficulty. I had to lift my oldest of my large dogs over many tree trunks.
This trail is one of the nicer trails at the State Park, after the recent tornado. The scenary is beautiful, the trail follows along side the guntersville lake, crossing several creeks. When we walked the trail, the creek beds were dry. The trail ends at a large rock bed creek, that enters lake guntersville, even though it was dry as well, it was very beautiful. The trail is approx 2.2 miles in. Then you return on the same trail, it took us about 2 hours to complete the in/out trail.
