Hi. I am from Seattle and am trying to plan a road trip to San Francisco, where on the way my girlfriend and I can have a few dispersed camping spots on the way-ish. If anyone has any ideas or places to look that would be great. Ideally want somewhere that can be pretty isolated, on the northwestern side of California, and somewhere near a lake or river. I have been trying to find places myself for the past 2 hours with various off roading or campground finding apps and I am completely lost. I drive a 2006 Subaru Baja so mild off-roading is good but anything major won't work. Thanks so much!
