Muir Woods Trails

This superlative piece of civil engineering is the most recognisable symbol of San Francisco, and an icon of the United States.

Part of the Golden Gate Recreational Area, this breathtaking redwood forest is named in honour of the famous naturalist John Muir.

Giant redwoods - Sequoia sempervirens - are the surviving species of the Sequoia genus, which can reach astonishing heights of up to 375 feet.

In Marin County, the quaint town of Sausalito is lined with sidewalk cafes and paths along the water, across the bay from San Francisco.

Completed just before the American Civil War, this fort defended the Bay against hostile warships.

Built for the 1915 Panama-Pacific International Exposition, this beloved iconic structure now hosts art exhibitions.
