I need good ideas for a vacation in California?

My dad and I are currently looking at vacation spots in California, we will probably be there for a good 1-2 weeks but were not
really sure where to go. Do you guys have any ideas where we could go?

What are good vacation ideas for California?

I am 16, my sister is 13, and my father is 36. We are going to California in July or August and will be staying near San Francisco. Last year we went to Florida and did amusement parks and stuff like that. We don’t really want to do that again. What are some good places to go to in California near San Francisco??

Ideas my dad has already: Golden Gate Bridge, Redwood/Sequoia Trees
