In early September the Bay Area Ridge Trail celebrates 20 years of trails by inviting hikers to a 5-day trek from Castro Valley to Martinez.
This may be as close to European hut-to-hut hiking as you can get in the Bay Area -- gear will be hauled from campsite to campsite and meals are included. The cost is only $50 a day, and hikers can do the whole 5 days or just one (as space allows -- those doing the whole thing get priority). There's only space for 75 hikers, so sign up early.
Read more here, and happy anniversary Bay Area Ridge Trail!
(I don't know the actual route for the hike, but here's a photo from the BART/ Wildcat Canyon Regional Park.)
