Coit Tower is a high point in Pioneer Park, San Francisco. It was built in 1933. The tower is 64 meters high. It has an old and tasty elevator to go up. It charges $8. The top of the tower is open, and you can watch San Francisco 360 degrees. It's worth visiting. There is a fully automatic toilet beside Coit Tower, free of charge, one person at a time, which is very characteristic. I suggest that curious friends try it: -) Down from Coit Tower, along the red line on the map below, there is a trail leading to the sea. In the downhill section, there are many beautiful flowers on both sides, so we must go for a walk. In the second half of the Red Line Trail, you can see the famous headquarters building of Levi s, which seems to be accessible. I have a travel book about San Francisco, with more information and pictures.
