Pacific Heights has the grandest houses in San Francisco and the best staircase, and the walk threads the two together before dropping you onto a proper shopping street. It's a walk about looking up at facades and out at the bay.
About three and a half kilometres, best in the afternoon. Start at the Haas-Lilienthal House, the one turreted Victorian you can actually go inside, then walk west along Broadway through the mansion row — walled gardens, consulates, old money kept behind hedges. The views west open between the houses as you go.
Then the Lyon Street Steps, the grand garden staircase dropping toward the Marina, banked with flower beds the neighbours keep. Stand at the top for the bay and the Palace dome, then take both flights down. Climb back to Alta Plaza Park, a terraced green ziggurat with the city on one side and the bay on the other, and end down on Fillmore Street — boutiques, coffee, and a jazz history marked along the lower blocks. The 22-Fillmore runs the length of it home.
