Scenic birthday ideas in or near San Jose?

I plan on celebrating my wife’s birthday on the 23rd of March in San Jose, we are from Oakland. I’ve purchased tickets for a 4:30 showing of circ du soleil. I want to go on a hike with something scenic and pretty things to look at. Can anyone recommend anything? It does not have to be a hike, but cool to experience (preferably free) would work too.

Could you also recommend a restaurant for lunch?

None of these need to be in San Jose, but ideally in driving distance to make the 4:30 show.

Thanks!
