All About Mount Diablo

From springtime blossoms to wintery snow-capped peaks, Mount Diablo offers natural wonders every day of the year.


Published:

Legendary naturalist John Muir once said, “We are now in the mountains and they are in us, kindling enthusiasm, making every nerve quiver, filling every pore and cell of us.” Visitors to Mount Diablo can still feel that deep bond—Muir himself spent a night on the summit in 1877—where expansive views across the Delta, beyond the Bay Area and into the California farmlands unfold below.

Save  Mount  Diablo,  a   land  trust  that aims to honor that bond with nature,   has worked with the government and local organizations to conserve hundreds of acres and preserve resources since 1971. “We want the community to develop a personal relationship with the mountain,” says Ted Clement, executive director of Save Mount Diablo. “If people don’t have that love and connection, are they really going to protect the land?”

Annual events like Four Days Diablo, a “glamping” trip planned for next year, and Discover Diablo, a new free hiking program, further that connection and showcase the region’s year-round beauty.

From the golden hills during summer, to the autumnal march of the mating tarantulas, to the snow-dusted greenery visible at higher elevations during winter, Mount Diablo has season-specific delights to suit every taste. Clement says spring is his favorite time on the mountain: “The wildflowers are at their peak; it’s an Alice in Wonderland type of experience.”
