For a close-to-home car-camp that doesn't require reservations months in advance, head to the Pantoll Campground on Mount Tam's southwest slope. Spreckled along a forested hillside, this first-come-first-served campground is ideal fora quick getaway—but you have to get there early to snag one of the 16 sites. Set at the intersection of nine primo trails, the camp offers loads of hiking options, including hikes to Muir Woods and Stinson Beach; the famous Dipsea Trail isn't far either. When hunger strikes, there's no shortage of cooking options: each site has fire pits, barbecue grills, and stone-built Diablo grills. Sit back, listen to the night sounds, and watch the moon rise over Mount Tam. Close to home never felt so far away!
