I don't know of any long trails around Chewacla. There are some nice dayhikes, though. There are some longer trails in Tuskegee - like the afore mentioned Bartram.
I found this:
http://www.alabama.travel...am_trail-bikingtrail.htmlThere is an interesting network of developed trails out on wire road but I've forgotten what they're called. It's a park but it has some interesting botanical points.
If you're interested in urban trails, there's a day long trail that runs from Riverview to Shawmut in Valley. There are some interesting points such as the swamps at the southern end (and there's a trail behind the mill in Riverview to the old dam and powerhouse) and the gorge at Langdale.
Also, Pine Mountain isn't far at all and the Pine Mountain trail is well worth the visit. It
is long enough for back packing.
