Classic image of Golden Gate bridge in San Francisco, California from Battery Spenser.
This shot was made on a 36mm full-frame equivalent lens. You probably can utilize a wider angle lens as well as using telephoto for capturing bridge details. Because of the ocean's proximity, it might be windy. I would recommend grabbing a sturdy tripod, at least. If you plan to shoot when the sun is relatively high and there is a lot of light in the scene, a set of Neutral Density filters might be beneficial. It also might help to smooth car lights in the evening, providing beautiful traces when long exposure.
I would recommend visiting this location any time starting September till late spring. During the summer months, it might be foggy, and you will not be able to see the bridge at all. Please, check the weather forecast before going to the location. However, during foggy days there are multiple other opportunities to shoot in this area. Check my other guides to get more details.
Sunset and sunrise work very well for this location. During sunrise, you might get sun into the shot rising over the city. Evening hours, depending on the weather, might benefit from nice sunset sky colors.
