Teen in SF

A 15yo girl relative is going to spend 3 weeks with us this summer. Her first visit to America. We’re going to be off work to spend time with her.

She speaks English fluently (as well as 3 other European languages), she’s massively curious, fun, funny, outgoing, smart, mature, polite, great with folk of all ages, eats anything, a total darling.

What do teens like to do these days ? What are unique things of San Francisco and nearby that teens like to see or experience? (In addition to things she’d plan.)
