Muir Woods is beautiful. We drove over the Golden Gate Bridge to get there, and were so happy that we did not let the opportunity to see this national monument go by. Established as a nature preserve in 1908, Muir Woods was a gift to the US government. It was named after John Muir, a famous conservationist who increased US awareness of the importance of preserving nature. A Redwood can live for 3,000 years, and many of the towering giants have been in place in Muir woods for centuries. There are a variety of hiking trails available to use depending on how much time and effort you want to expend in the woods. The main loop is a very leisurely hike that takes about a half an hour. There are other hikes, however, that would take most of the day. Admission to the woods is only $2/adult. Buy a trail guide as well so that you can map out where you are going. Wear good shoes.
