Muir Woods National Monument contains 6 miles of trails. There is a 1/2 hour loop, a 1 hour loop, and a 1 1/2 hour loop as well as longer hikes on trails that extend into surrounding Mount Tamalpais State Park.
I went over the weekend for a day trip. Arrived around 10AM and the parking lots were already full. Parked outside along the road amongst other cars. Walk to the entrance and showed them our annual pass. If you don’t have an annual federal parks pass, it will cost you $7/pp or you can see which deals will be best for you. The payments goes towards the upkeep of federal parks. It is very nicely designed for easy stroll. If you’re more adventurous, check out the hiking trails.
I did the Muir Woods trail that takes you into Mt. Tam and loop back around. It was a pretty nice hike!
