If you are looking for a nice overnight escape from the SF Bay Area, head up the coast to the Albion River Inn. Located about 15 minutes south of Mendocino , the Albion River Inn has a set of charming cottages perched atop of a cliff overlooking the mouth of the Albion River. Most rooms have fireplaces, and some have whirlpool tubs, but all have spectacular views. Sunny days are simply breathtaking.
Note that this is the Northern California coast, so the temperature and fog is totally unpredictable. Luckily, cold and foggy days make this place even more cozy.
Got a few hundred bucks and a weekend to spare? What are you waiting for?
