If you have young kids and you want to take them somewhere for quick and easy camping trip, Pantoll Campground is a great choice. It's not far from the Hwy 101 in Marin County but you leave the city behind as you drive up Mt. Tam and the scenery changes quickly. This spot is popular so it's a great choice for a last minute weeknight in the summer or weekend in the winter. It's also nearby the coast and some great hiking trails on Mt. Tam. NOTE - it's a hillside campground and you may have to schlep your stuff up the hill to your campsite. Enjoy!
