Coosa County is home to Lay Lake, Lake Martin, and Mitchell Lake. They were created as part of a hydroelectric power system developed in the early twentieth century. Recreational opportunities are found at all three lakes. Flagg Mountain, the most southern mountain of the Appalachian chain, is in Weogufk a State Forest. In addition to a loop trail for hiking and birding, there is a historic tower built by the Civilian Conservation Corps during the 1930s. Old Rock Jail, in Rockford, is listed on the National Register of Historic Places as the oldest jail in Alabama. The county’s largest town, Goodwater, retains many elements from its days when coal powered trains stopped to refuel there.
