Camera Obscura
The Verdict
"Go on a clear, sunny day; the projection needs direct sunlight. Pair it with a walk on the Lands End Trail past the Sutro Baths ruins next door."
What you need to know
The Camera Obscura is a small wooden viewing structure at the edge of Lands End, next to the Sutro Baths ruins, where a rotating lens and roof mirror project a live image of the coastline onto a white parabolic dish about six feet across, using only optics with no electricity in the projection.
How It Works
A camera obscura focuses outside light through a small opening onto a darkened surface. This one adds a rotating mirror that scans the horizon, so the scene moves slowly across the dish and you can watch waves and walkers in real time. The structure was built in 1946 by Floyd Jennings, is one of the few publicly accessible camera obscuras left in the US, and is listed on the National Register. The shed is small, and the projection needs daylight on the lens to read clearly.
While You’re There
The Camera Obscura shares its lot with the Sutro Baths ruins and the start of the Lands End trail, which runs east toward the Legion of Honor and south to Ocean Beach.

Pro tips
One of only a handful of camera obscuras left in the world. Combine with a walk along the Lands End Trail and the ruins of the Sutro Baths right next door. Skip it on foggy days — the projection needs direct sunlight to work.
