There is so much to see and do here, and all so close to SF. Great views from the Tam Lookout, and this is where mountain biking was invented. Sadly, not much single track, but the railroad grade from mill valley is a classic ride. A couple hours easy pedaling up, and about a half hour down. End up at Joes Taco Lounge in Mill Valley for tacos and beers, and you are living my friend. It does not get any better. Stinson beach on the other side is a great trip, but the water is way cold.
