Mount Tam East Peak offers some of the most majestic views north of the bay. From this vantage point, you can see all of Marin, along with Point Reyes to the north and Oakland and San Francisco to the south. The stunning panoramic vistas make the journey well worth the effort. There are restrooms and picnic tables, ideal for a snack or lunch while you capture some incredible photos.

We are very impressed by these huge trees. I couldn't capture the full size with my camera, so I'm adding a few cell phone photos as well. The largest specimen in Mui Woods is 78 m high, about the same height as a 23-story building.
