San Francisco is a city of contrasts, where you can feel the cutting edge of the times and yet feel at home. Walking along the oceanfront, feeling the heat from the people of Silicon Valley, the cool breeze coming from the California Current is pleasant in summer. The waterfront is crowded with seafood restaurants using local ingredients. After lunch, cross the Golden Gate Bridge and take a walk up the hill to visit a number of interesting wineries. The smell of fresh grapes, the sweet smell of oak barrels.... Such a wonderful experience awaits you.
