Allow me add some comments about Pt Reyes light. It's a longer drive from San Francisco than it appears on the map. Hwy 1 is a beautiful drive but it's s-l-o-w. Once you enter the Pt Reyes Park, it's another 20 miles to the lighthouse, and that's not a short drive either (plan on 35-40 minutes at least). It's a narrow, twisting, winding road that can be difficult to pass on. From the parking area there's a bit of a walk to the stairs which take you DOWN to the lighthouse, WAY DOWN. Plan on spending a fair amount of time getting back up those stairs - it'll seem like you're climbing a mountain. Having said all this, it was well worth the journey. The light is perched on a high, rocky, remote point of land that juts well into the Pacific. The rangers give a tour of the lantern room and briefly actuate the lens rotation mechanism. If the weather is clear (as it was when I visited), you can see forever. Look for the redtail hawk flying along the cliffs below.
Enjoy.
