Because of the weather in Alabama from May through September, I would only recommend this hike in both directions during the winter, fall, and early spring months when the air temp is still hovering in the 60s. However, in the Summer, the trail is a delight to hike down (starting at Cheaha State Park and hiking towards Talledega) even though the Summer heat is brutal. There is plenty of water along the trail but, a 100 oz camel back should be sufficient. Hiking downhill, the trail can be completed with a moderate pace in 4 - 5 hours. For those in excellent shape, the trail can be hiked both ways (roughly 18 - 20 miles) in 8 - 10 hours. For safety, I recommend bringing at least an LED headlamp, just in case you get caught in the dark.
When I hike round-trip, I start at Talledega and hike to the top of Cheaha making the return trip mostly downhill. I carry my camelbak, a water filter, a headlamp, and some food.
There aren't many views from the trail but there are 2 or 3 waterfalls (this is a creek so they aren't very big but they are still nice to look at) and the trail is kept in pretty good shape all year. It is also rarely hiked from end to end with the Cheaha side being the most frequented because of the waterfalls.
There are also a few excellent camp sites along the trail. I highly recommend this trail for trail runners and hikers.
