North Peak Direct. Almost 3000′ gain in 2.5 miles can be found on the east side of Mount Diablo. On Morgan Territory Road, one quarter mile from its intersection with Marsh Creek Road is a small pullout with an official gap in the fence. This pullout is on the right just past a mine’s tailing pond. Once through the fence, you may have a seasonal stream to cross, but on other the side you can see a utility road heading up, serving the two powerpoles a third of the way up North Peak. Follow the road to the second powerpole where a post marks a singletrack that goes mostly straight up to the summit of North Peak. This trail appears on some hiking maps but not on the official Mount Diablo State Park map.
