Muir Woods, San Francisco, California. 11 miles north of the city. Take the 101 to Hwy 1/Stinson Beach exit and follow signs. Hindsight - the "tree talk" by the first landing area is really well done. We walked up to bridge 4, then back to Fern Creek, up to Lost Trail, up to the Panoramic Hwy, doubled back to Ocean View Trail, and back to the trailhead. The kids loved it. There were only 3 spots our 9 yr old asked for someone's hand.
