Stroll through the grand Nob Hill residences along California Street, which were once home to the mansions of the Big Four railroad tycoons.

Explore Huntington Park, which is set in the footprint of the original mansion of Central Pacific Railroad baron Collis P. Huntington. The 1906 earthquake destroyed the mansion, and Mr. Huntington’s widow donated the grounds to the city to establish a park in 1915.

Visit Grace Cathedral, which sits on the grounds of the mansion of railroad baron and banker William Henry Crocker. He subsequently donated the land after the 1906 earthquake, as well.
