Pier 41, Marine Terminal Box Office Tips
When the signs say "stay on the trail," DO THAT, because Muir Woods' ecosystem self-enforces: because poison oak and stinging nettles are native to Muir Woods, those who maintain the park let it grow wherever it wants to off of the trails! Also, if you bring lunch, eat it on the bus -- don't even think about eating in Muir Woods. The park rangers are VERY serious about the wild animals not getting human food.
The weather was foggy, but not windy. Muir Woods' tall redwoods keep a lot of wind out.. I wore a velour top and a jacket. I was very comfortable..
