Petaluma River Turning Basin

Petaluma, CA

The Petaluma River turning basin is a widened section of the navigable river in downtown Petaluma where historic boats and small craft moor. The calm water provides mirror-like reflections of the surrounding Victorian-era waterfront warehouses, particularly at dawn. The McNear Building and other brick structures along the basin date from Petaluma's 19th-century river commerce era.
