From the launch ramp on Highway 1 in Jenner, one can paddle the wide mouth to where the river meets the ocean, and on a calm day, it's possible to go out through the surf. Otherwise the mouth accesses the wide beach at Goat Rock State Park.
One can also paddle around the large island across from Jenner or even paddle several miles up river (not in rainy season when the river is flowing).
Up river, under the Highway 1 bridge, continue to the south side of the river to explore some wetlands channels.
There are many places to eat and stay on 116 in Duncans Mill and Guerneville. River's End in Jenner is an ideal place to stay, and there is camping a few miles north at Salt Point State Park and a few miles east on 116 at Armstrong Woods.
Located on Highway One where Highway 1 meets Highway 116 in Sonoma County. Reach the area from 116 out of Santa Rosa/Sebastopol or Petaluma via the road to Bodega Bay
There is a public parking lot and launch ramp in Jenner, on Highway 1, easy to spot from the road.
