Hi @Alicia8338 - Thanks for reaching out. It's great to hear that you and your son are gearing up for some hikes in your new area!
A beautiful trail that you might want to check out is the Lake Siskiyou Trail Loop — on clear days you'll even have gorgeous views of Mt Shasta!
Hopefully some other folks will weigh-in with their recommendations too. @Ana-hikes, @maggiesch, @angelaf, @Luchy, @Cbobgo - do y'all have any easy/moderate trails in Northern California that you'd suggest?
