This is a beautiful metric century (60-ish miles) taking you through Sebastopol, Occidental, and then through some coastal hills and back to Petaluma through the idyllic farmland of Chileno Valley. Covers some of the same area as our Freestone Loop (ridewithgps.com/routes/31800172), but with more climbing and about 13 added miles.
Your best stop is the Union Hotel Bakery (get a turnover, or a pie with cornmeal crust if any are left) or Howard's Cafe. Unless it's a Friday through Monday, in which case you might want to press on to Freestone to stop at Wild Flour Bread. Decisions, decisions.
