Anything that goes over to the coast and back are my favorites. Like up Page Mill, down West Alpine, left on Pescadero, the right on Stage Road, left on Highway 1 and up Tunitas Creek, and then down Kings Mountain. Or any the other variations using Old La Honda, or Kings Mountain to get up to Skyline and then use Highway 84 to go down.

Going to San Francisco and back is kinda cool, but not very scenic. Going the opposite way to Santa Cruz along highway 1 is pretty nice. However during these months I generally stay on the east side of the mountains.
