Mobile-Tensaw Delta
5200 Battleship Pkwy, Spanish Fort, AL
Spanish Fort, AL
A watery wilderness of cypress swamp, marsh, and winding bayou spreads north of Mobile Bay here, one of the richest and least-known deltas in North America.
The Mobile-Tensaw Delta is one of the largest river deltas in the United States, a sprawling maze of swamp, marsh, bayou, and floodplain forest that fans out where the Mobile, Tensaw, and several other rivers converge before emptying into Mobile Bay. Its size and its astonishing richness of life have earned it the nickname America's Amazon.
Stretching across some 250,000 acres, the delta is a labyrinth of waterways lined with bald cypress and tupelo, opening into wide marshes near the bay. It is one of the most biologically diverse places in North America, home to an extraordinary range of fish, birds, reptiles, and plants, much of it protected in state and federal wildlife areas and best explored by boat.

Learn about Mobile-Tensaw Delta
America's Amazon
The delta earns its nickname through sheer abundance. Fed by rivers draining a huge portion of Alabama and beyond, it collects sediment, nutrients, and life from across the region and concentrates it in a shifting mosaic of open water, marsh, and forested swamp. Scientists count the delta among the most biodiverse spots in the country for fish, turtles, snails, and other freshwater life.
This richness is not obvious from the highway. The causeway across the bay hints at the marshes, but the true delta lies to the north, a green wilderness reachable mainly by water. Winding through its bayous by boat or kayak, past knees of cypress and curtains of Spanish moss, is the only way to really grasp its scale and quiet.
A crossroads of history
Long before Europeans arrived, the delta and the bluffs along it were home to Native peoples, ancestors of the Muscogee, Choctaw, and other Southeastern nations, who fished its waters and built settlements on its edges. The delta later became a contested frontier among French, Spanish, and British claims, and towns like Spanish Fort and Blakeley grew up along it.
The upper delta was also the setting for one of the last major battles of the Civil War at Fort Blakeley, and its waters carry another sober piece of history: it was here, at the head of Mobile Bay, that the Clotilda, the last known ship to bring enslaved Africans to the United States, was scuttled and sunk in 1860. Its wreck was confirmed in the delta's muddy waters in recent years.
Wildlife of the swamp and marsh
The delta teems with life. American alligators bask on the banks, and the marshes and open water host wading birds by the score, herons, egrets, ibis, and roseate spoonbills, along with ospreys and bald eagles that hunt the shallows. Migrating and wintering waterfowl fill the lower marshes in the cooler months.
Below the surface, the delta is a nursery for fish and shellfish that feed Mobile Bay and the Gulf, and its swamps shelter turtles, snakes, otters, and mink. Black bear range the wilder upper reaches. The plant life is just as varied, from towering cypress and tupelo to floating mats of vegetation and the pitcher-plant bogs found nearby, making the whole delta a living catalog of Gulf Coast wetland life.
Season by season on the water
Spring brings mild weather, blooming wildflowers, and nesting birds, one of the finest times to paddle the bayous before the heat sets in. The delta is green and alive, and the water is comfortable.
Summer is hot, humid, and buggy, best tackled early in the day and with plenty of repellent, though the wildlife is abundant. Fall cools things down and brings the first waves of migrating birds, an excellent season for a boat tour. Winter is quiet and often mild, the marshes filling with waterfowl and the bare cypress opening long views across the swamp.
