Great trail by East Bay standards. Nothing too wild, bit flowy in places with a few fun root sections to pop over. Like another commenter said, it’s a good trail to build skills on. Overall pretty + generally primo dirt quality in the redwoods.

Great trail for beginners to work on skills, and it gets to be a lot of fun once you know the route!
chriswiles
One of my favorite trails I have ridden. One of the best in the Bay Area. Great flow, fully shaded, redwoods.
We hope you've been enjoying Trailforks!
