Hi, we plan to come to California for spring break (first week in April) about would love suggestions. A suggested 6 day travel route would be really helpful. Hoping to hit some nature (hikes etc) highlights, maybe walk around few college campuses. We don't need to do any of the huge touristy things like Disney or amusement parks. Our kids are 13 and 15 and fairly active. I think we would rather go to Northern California but we are considering a more southern trip due to the weather at that time of year.
