The redwood trees here are some of the tallest trees in the world, although the biggest trees belong to the sequoias located in both Yosemite and Sequoia National Park, both southeast and roughly 3-5 hours drive from San Francisco.
Admission in 2017 was $10 per person, but is covered with the annual pass which costs $80 at the time. So if you plan to visit a few national parks, this may be worth getting. When we went, parking we were told, is limited and it is true, so do make sure to go ahead of time. I did notice that when I checked the official site Muir Woods, starting in 2018, parking permits will be required. I guess this is to curb the amount of illegal parking that takes place if you go late in the day. It looks like parking will be $8 (it was free when we went) or $3 per person for the shuttle. So it does add up pretty quickly.
When you get there, there is only one entrance and one main hiking trail which takes roughly 1 hour to complete. While there, we actually saw our first buck! Very cool to see wildlife in their natural habitat.
With the parking/shuttle situation, I think it will not be as busy, but at the same time, I'm not sure if it is worth visiting if you have already seen the sequoias. If I had to pick one, I would say go see the sequoias.
