Cahaba River, Free-flowing river system in central Alabama, United States
The Cahaba River is a free-flowing river system in central Alabama that stretches for about 194 miles through varying landscapes. It starts near Birmingham and flows toward Selma, where it joins the Alabama River, passing through forests, open areas, and rocky sections along the way.
The river was home to Cahaba, Alabama's first capital, which sat on its banks from 1820 to 1825. This settlement was significant in the state's early years before the capital relocated elsewhere.
The river's name comes from Choctaw peoples who lived in the valley and called it "water above." This indigenous heritage remains woven into the local identity and the stories people tell about the land.
The best time to explore is spring through fall, when water levels are stable and weather is pleasant. You should know that different sections have different access points, so checking local information or joining a guided visit helps you find the best spots.
The river is home to the rare Cahaba lily, which grows only on rocky bottoms and attracts sphinx moths for pollination. With over 130 fish species, it is an important spot for freshwater diversity in the southeastern United States.
