Take Route 1 north through Jenner, and continue on an hour or so to Sea Ranch or Gualala. Take 101 north from Golden Gate Bridge to East Washington St. exit in Petaluma. You will continue north on East Washington St., which turns into Bodega Bay Highway and later Route 1, as you head west and north through Bodega Bay to Jenner, and up the coast to Sea Ranch and Gualala. They call it a Banana Belt. The weather is often great, and usually 5-10 degrees warmer than nearby coastal spots, though naturally cooler than inland.
Summer is the foggiest season, fall the clearest and best.
Spring sees some storm activity, but locals say beautiful days in the 70s and 80s are not uncommon. En route, through the Russian River Valley. A Sonoma coastal winery. Well, almost coastal. Open noon to 5 p.m., daily.
