If you ever get the chance, I highly recommend that you do a bike ride across the Golden Gate Park. I love being a tourist in my own city! There’s really only one part that’s strenuous and the rest of the ride is easy. It does get chilly because of the wind so I’d recommend that you take your camera, a wind breaker, and comfy shoes. Once you cross the bridge, you’ll end up in Sausalito where you can park your bike and walk around the town. The houses are beautiful and it’s worthwhile to just sit somewhere, get some ice cream or food, and look out by the water where you’ll see San Francisco in the distance.
