If you are thinking of running white water, see
Alabama Whitewater Paddling Guide, and look for "Town, lower" in the Run Index. If you are thinking about paddling the lake backwaters of Town Creek, the only put-in access I know of is the take-out described in the whitewater run. It's been a long time since I've been there but it used to be a 1/2 mile or more carry down a washed out forest road and then through the woods. The Birmingham Canoe Club meets monthly and I'm sure they would be glad to help. They are at
Birmingham Canoe Club. No matter what you end up doing, be sure to check out High Falls on Town Creek. See picture at alabamawhitewater.com. Good luck. It's a beautiful area.
