The Point Reyes Lighthouse contains the ORIGINAL first order Fresnel lens and clockworks that were…read moreon display at the 1867 World Fair in Paris. Not just a replica, but the actual model that was actually on display in Paris.
The best time to see the inside of the lighthouse (where the lens and clockworks reside) is typically on weekends between 10am-noon and 1:30-3:30pm, but only in winds under 40mph, and (ideally), when it's not foggy.
(Check the park website or call for current hours, which may fluctuate.)
During these hours, rangers and volunteers are often around to answer questions, give educational talks, and sell merchandise.
For safety reasons, the lighthouse and stairs are always closed to the public when the winds exceed 40mph-- which happens often. This is the windiest spot on the west coast.
When you check the wind online, the results come from a weather station miles away from the lighthouse. Wind speeds may be much higher at the actual lighthouse than what you see online.
To avoid wasting gas and time, you can always call the park visitor center (after 10am) to ask about the winds for that day.
The Point Reyes lighthouse parking lot sits about a quarter mile away from the viewing platform above the lighthouse. This portion of the trail is accessible. There is also a closer accessible lot for those with handicapped placards.
From the viewing platform, it's 313 stairs plus two steep slopes (of about 100 feet each) down to the actual lighthouse.
The reason the lighthouse sits so low below the viewing platform is because the heavy fog that plagues the area is often just above this level. So, it's essentially below fog level-- except for when it's not.
For those circumstances, there are foghorns. The modern foghorns are controlled by the coast guard, and are not on display.
However, a large equipment-building-turned-museum, which sits at the same level as the lighthouse, houses several of the historic horns and air compressors, along with a few interpretive signs.
In my personal opinion, the lighthouse could use a lot more pictures and interpretive signs. I personally think that it would be cool if these were plastered all over the inside of the lighthouse, like they are in Heceta.
Is it worth the 313 stairs to see the lighthouse?
I am the wrong person to answer this question, since, for me, the stairs have always been my main motivation for visiting. I would climb these stairs just for fun, and I've done so many times.
And yes, I bought one of the "I survived the climb!" stickers from the visitor center at the top of the stairs, which is typically open the same hours as the lighthouse.
The lens itself is pretty chipped up, but still beautiful to look at. I'm not sure if the chips are due to the weather, historic vandalism, or routine maintenance.
What I do know is that the glass is technically irreplaceable. The original glass was made by French artisans in the 1800s. The modern replacement glass is manufactured in England, from different sand, which is apparently a different color and clarity than the original.
Typically speaking, even when on display, the lighthouse is not rotated, and the curtains are kept mostly closed. Some people (me) might argue that it's deceptive to call it "fully functional" or claim that it's "in working order."
That being said, the clockworks (a cabinet full of gears, pulleys, and cables) is pretty cool too see. It looks like a giant nineteenth century wind-up toy. The park keeps it painted, polished, and well-maintained.
National Lighthouse Day is coming up on August 7th. Historically, including last year, the park has operated the lighthouse for this event.
I haven't seen anything online about it yet, but maybe they'll celebrate this year, too.
The nearest gas and food to the lighthouse are about thirty minutes away, so make sure you plan for that ahead of time.
Chimney Rock is a short drive away. Drake's Beach (including the Ken Patrick visitor center), North Beach, South Beach, and the Cypress tree tunnel are all passed on the road between the lighthouse and Inverness, so if you plan right, you could definitely knock all of those sights out in one day.
If you're a real overachiever, you could also add Tomales Point/Pierce Point Ranch to the same day, as the road to these destinations is between the lighthouse and Point Reyes Station.
