Mount Diablo SP
Abbreviated as "#GSTA" on the Reserve California site
Many visitors to Mount Diablo head straight for the Summit to enjoy the famous view. As mountains go, Mount Diablo isn't particularly tall - only 3,849 feet. However, it is surrounded by low, rolling hills and broad, flat valleys, so the view from the Summit is remarkable. When conditions are best, you can see almost 200 miles. Summer days are sometimes hazy, and the best viewing is often on the day after a winter storm. Quiet hours: Quiet hours are from 10 PM–6 AM. Campfire restrictions: Campers must use stoves or fire pits, and there are restrictions during fire season. Overnight lock-in: Campers are locked in the park from sunset to 8 AM. Campsite size: A maximum of eight people and two vehicles are allowed per campsite. Reservations: Reservations can be made up to six months in advance on the Reserve California website. Campground options: There are several campgrounds, including family campgrounds, group campgrounds, and a smaller campground for tents. The Junction Campground has six tent sites and is available on a first-come, first-served basis. Safety: Tell someone where you're going and when you plan to return. Many trails have limited cell service and can be remote.
