Island Between Bridges: Exploring San Francisco’s Treasure Island on Foot
A compact coastal jaunt with skyline views and a century of engineered history
The wind on Treasure Island arrives like an invitation—bright, insistent, smelling of salt and city. You step off the Bay Bridge into a flat, open geometry of concrete and grass where the skyline to the west sits like a postcard framed by the Golden Gate and a ribbon of bridge steel. For a compact afternoon of walking, photography, and a little bit of history, San Francisco’s Treasure Island is a sharp, civilized escape: a man-made spit of land that rewards low-effort travel with big perspectives.
Trail Wisdom
Layer for wind
Wind off the bay can be stiff even on warm days—bring a light windproof jacket you can tie around your waist.
Hydrate before you go
Water refill points are limited—carry a full water bottle for the 2–3 mile loop.
Time for golden hour
Arrive an hour before sunset to set up shots of the city skyline across the bay.
Stick to paths
Respect fenced restoration areas and walk only on established trails to protect newly planted habitats.
