Above: Pacific Coast Highway Ride Leg 2: from Fort Bragg to Pacifica with
side jaunt to Point Reyes Headlands and the lighthouse (detail shown
below).
Below: Detailed map of the junction of US101 and the road in to Marin Headlands. This road is steep, narrow and often crowded with cars and tour buses. Extreme caution is advised. If you get onto the one way section, the down grade appears to exceed 20 percent (I was using my brakes in first gear with the throttle closed) and you will have to take the long way around to get back out to US101. The views of San Francisco and the Golden Gate are incomparable but, please, be careful.
Below: Detailed map from junction of CA1 and US101 at Mill Valley, across
the
Golden Gate Bridge, through San Francisco and on into Pacifica

From Fort Bragg take CA1S into Pt. Reyes Station. At the south end of Pt. Reyes Station, turn right at the signs for Pt. Reyes National Seashore. Continue on that road, through Inverness to the parking lot at the Pt. Reyes lighthouse. Return to CA1 via the same route. Upon reaching CA1, turn right (south) and continue on CA1S into Mill Valley to at T-intersection and stoplight. Turn right and continue on to the junction with US101. Take US101S across the Golden Gate bridge into San Francisco. Turn off US101 onto CA1 about 1/4 mile past the toll gates (bridge toll is $2.00/ $3.00 except during rush hour when it is free for motorcycles). Follow CA1 (19th Avenue and Junipero Serra Blvd.) through San Francisco until it joins with I280S. Turn off I280S onto CA1S at the Pacifica exit; take CA1S into Pacifica.
