About 1.5 hours south and west of Huntsville is the Bankhead National Forest. Has the 25000 acre Sipsey Wilderness Area ,some good hiking trails and if Sipsey River is flowing good you can float or canoe down it. I think there is a place you can rent canoes, Not far is Houston Recreation Area (Campground) on Lewis Smith Lake sometimes has some pretty good fishing.
