Coit Tower is a 210' tall art deco tower built in 1933 on the top of Telegraph Hill. You can take an elevator to the top, and I think you can walk up on Saturdays.
Walking up would be a plus, because the inside of the stairwell is covered with murals. The murals were painted by 27 different artists. We saw some of them on the bottom floor, but I would have liked to see more.
The detail on them is amazing.
On the top floor lookout, we got a great view of the foggy Golden Gate Bridge.
Wait a minute! What's that! It's a fireboat leading -
A Navy ship into the harbor. It's passing the cruise ship Crown Princess here.
I later found out this is the USS America, an amphibious assault ship that was scheduled to be commissioned in San Francisco that next weekend.
The crew were standing all around the edge of the ship. Very cool!
We then headed over to the Pacific Ocean side of town. We went to the viewpoint for the concrete ruins of the Sutro Baths. They were built in 1894, and filled by the high tide. The whole story of the baths is incredible, and you can read it here.
South of there we came to Moss Beach, where you can venture into the tide pools at low tide.
We did see a few strange creatures.
The Harbor Seals liked the area too, but they stayed out far enough so we couldn't get too close.
Five miles south of San Francisco, in the Devil's Slide area, is an odd looking hanging bunker perched on a sandstone pillar.
It was a military triangulation station and observation site used during World War II as part of the harbor defense of San Francisco.
