If your idea of a perfect vacation includes hiking, camping, or looking out across majestic vistas, then northern California has more than a few world-famous sites that should be on your must-visit list. There are towering redwood trees, spectacularly deep cliffs, and ocean-side panoramas. You can make an entire vacation out of visiting any one of the region's national or state parks, or you can spend a few weeks driving from one to the next to enjoy every last natural highlight that the area has to offer.
