Mt. Diablo State Park: Back Canyon Trail Professional Review and Guide
"This loop, combining parts of the Donner Creek, Back Creek, and Meridian Point trails, and Back Creek, Meridian Ridge, and Donner Canyon roads, offers a wonderful sample of the joys the north side of Mt. Diablo has to offer. Cool, shady canyons, exposed rocky ridges, chaparral-covered hillsides, and oak woodlands compete for your attention with a terrific assortment of trees, shrubs, wildflowers, and birds. In spring, consider extending your trip to visit a set of hidden waterfalls by following the Middle and Falls trails as described in “Falls Trail,” elsewhere in this book. The Back Canyon Trail and the lower part of Donner Canyon Road may be very muddy in wet weather."
