Don't forget to look up for today's #SFOutdoors! There are really tall trees on the horizon. Located to the north of us stand some of the most majestic trees in the country. This area, called Muir Woods National Monument, is named after John Muir, the noted conservationist. Containing six miles of trails, one can easily get lost among the trees. To explore more of this beautiful area, hit the blue button up at the top. Photo by jiezhen. Have you been here before? Share your memories in the comments. #MagicHourSF
