I grew up there but I didn't really start to appreciate it until I moved away. Napa is nice, but in my opinion, Sonoma County is tops.
  1. Get a beer flight and pizza at the Russian River Brewing Company
    The most important thing you need to know about this place is that it is where Pliny the Elder (and once a year, Pliny the Younger!) comes from. They make super-hoppy beers and chocolatey stouts, along with fantastic pizza.
  2. Go for a hike at Annadel State Park
    Whether you're an avid trail runner or a high school student looking for a place to smoke pot, Annadel is where it's at. Note: on hot days, bring plenty of water and sunscreen because there is limited shade.
  3. Sonoma Taco Shop
    This may be for purely sentimental reasons,as it was the location of many a brother sister lunch. That being said this local Taqueria has authentic delicious Mexican food that's both healthy and affordable. I have many a fond memory of ordering Connie Asada soft tacos will my sister munched on a bean and cheese burrito and we both rolled arise over the latest ridiculous thing our parents recently said.

  4. Taste olive oil at The Olive Press
    Truly some of the finest olive oil available in California, and tasting is free. Be sure to also try the fig balsamic they sell.
  5. Taste wine at Cline Cellars
    Right across the street from The Olive Press. Big Break Zin and Cashmere are my favorites.
  6. Do a food and wine pairing at Mayo Family Reserve Room
    By appointment only but very reasonably priced and tasty.
  7. Walk down Main Street in Sebastopol
    Quirky, hippie-driven shops and great vintage stores.
  8. Spend the day in Bodega Bay
    A sleepy beach town filled with artists and surfers. Lots of interesting antiques on the main drag, salt water taffy, and lovely beaches.
  9. Eat clam chowder at Lucas Wharf
    While you're in Bodega, get a bowl of creamy clam chowder at this iconic, old-school seafood restaurant, overlooking the water. The fish and chips are good too.
  10. Lunch or dinner at The Girl and the Fig
    This is non-negotiable. It's Sonoma eating at its best. Buy some fig jam to take home with you afterwards.
  11. Lunch at El Molino Central
    Some of the best Mexican food I have ever had. Tortillas are handmade and ingredients are local and organic.
  12. Walk around downtown Petaluma
    Lots of great coffee, shops and antiques. Very, very cute.
  13. The Sonoma County Fair and/or The Harvest Fair
    If you're in town in summer or fall, check these out. A great way to spend the day.
  14. Get coffee at Flying Goat Coffee
    Dark roasted coffees, delicious espresso with great foam art. Really good pastries. Cool vibe.
  15. Copperfields Books and Music
    There are several locations but the Santa Rosa one is my favorite. I spent hours here every weekend when I was a kid. Great selection of mainstream, current stuff, as well as more obscure and local picks.
