Snow enthusiasts can occasionally enjoy short-lived snowshoeing or sledding opportunities on the higher slopes.

Marsh Creek, Walnut Creek, and several smaller streams receive runoff from the mountain, providing important water sources for wildlife and contributing to the area's ecological diversity.
The name "Mount Diablo" has an interesting history. It is believed to have originated from the early Spanish explorers who named it "Monte del Diablo," meaning "Thicket of the Devil" or "Devil's Mountain." The name may have been inspired by the challenging terrain, thick vegetation, or the mountain's appearance during certain weather conditions. Legend has it that the mountain was also associated with supernatural occurrences, adding to its mystical reputation. Today, Mount Diablo continues to captivate visitors with its natural beauty, rich history, and awe-inspiring vistas.
