You have a lot of hills to choose from in San Francisco but in my opinion the best (and most varied) views are from Bernal Hill. Bonus: from my kitchen table I can watch tiny blobs moving around on this hill-- slow blobs are people, fast blobs are dogs.
I love visiting Land's End early in the morning when the light is new and the city is waking up. There's a spectacular view of the bridge and the north bay. Makes me grateful to live in San Francisco.
At the midpoint of the Filbert steps, near tourist favourite Coit Tower, The Malloch is a streamline Moderne gem built in 1937. I discovered it after watching Dark Passage, a 1947 Bogart and Bacall film noir. Lauren Bacall's character lives on the third floor and Bogey holes up there. A Deco beauty cruising towards the Bay. It has the coolest lift ever.
