The Petaluma River is perfect for a peaceful paddle and some birdwatching. The San Pablo Bay Wildlife Area covers 11,000 acres from the mouth of the river to Gallinas Creek. By kayak or powerboat, you can venture upstream and quickly find solitude and excellent long-distance views. When the wind is down, stand-up paddleboards and canoes are also a fun option. The mouth of the river is a great spot for fishing from both shoreline and boats.
