This route takes you through most of Mount Diablo’s biomes, starting in the riparian (streamside) habitat of Donner Valley; it takes you through oak woodlands and chaparral shrublands on the way to the top.

This is a difficult route that’s generally isolated and very exposed to the sun, so make sure to be prepared and dress accordingly. Depending on the time of year, it can be more than 100 degrees or covered in snow at certain points.
