Marsh Creek Road
Highlight (Segment) • Cycleway
While it's fairly straight over its first six miles or so, Marsh Creek Road changes its overall direction after that sixth mile and starts following the bed of its namesake creek. This part of the road is substantially curvier and gets more so the further you go west, back into the East Bay hills. The tree cover also begins to return along this stretch, though you never really enter a forest setting and I wouldn't say this stretch has enough shade to be of any help to those doing the ride on a hot day.
When Mount Diablo's North Peak enters your view, it's a signal that your time on Marsh Creek Road is coming to an end.
