Muir Woods is a spectacular National Monument park just across the Golden Gate Bridge from San Francisco. The park is extremely popular and starting 2018 they require RESERVATIONS for parking and/or the shuttle at the park. Donna’s friend Kelly clued us in about the reservations so I had made them a week prior. Our reservation was good between 10:30 and 11:30 am. During busier times the reservation would have had us parking near Hwy 101 and taking a shuttle in. The shuttle adds about a 45 min ride each way. We are here off-season so we were able to park in the main lot. The main loop in Muir Woods is about 1/2 mile long from the visitor center and is wide, flat, and in most places paved. This make the park very accessible for those less physically capable. This parks sees many elderly, handicap, and children in strollers as a result. There are many giant redwoods on the main loop and the trees are incredible. It is a magical and beautiful place. The main loop was pretty crowded and loud. There are 4 or 5 trails off of the main loop and we took the Fern Creek 1.6mile loop trail. This trail starts near the end of the main loop. The trail was much more peaceful and quiet than the main loop. It also was very beautiful and followed a very nice babbling creek. The trail had many big redwoods but not as many giants as the main loop. It took us about 3 hours to see the park, but you could easily spend all day if you are up to the additional trails. The Fern Creek trail had about 180 feet of elevation change and we were pretty tired after our hike. I think this park is a must see if you are in the San Francisco area.
