Pass A L'Outre Light

Pass A L'Outre Light is a lighthouse with a cast iron tower and brick lining standing at the mouth of the Mississippi River in the Birdfoot Delta. The structure sits surrounded by mud, with the tower still visible above the water.

The lighthouse was built in 1852 and first lit in 1855 to guide ships through the Pass A L'Outre channel. It was deactivated in 1930 after serving as a key navigation aid for decades.

The structure shows how important river navigation was for Louisiana's development, and the ruins stand today as a reminder of that era in the Delta.

Access requires boat travel through the Delta National Wildlife Refuge with coordination through the U.S. Fish and Wildlife Service. Visitors should prepare for wet and remote conditions with appropriate gear.

The structure has sunk into the Delta's mud over the decades, steadily losing height. The lantern fell into the water, making the ruins today a striking testament to nature and decay.
