What to do
Hiking Mount Diablo trails: Access numerous hiking paths ranging from easy to challenging at Mount Diablo State Park, with trails leading to panoramic viewpoints.

Explore Rock City formations: Climb and explore the unique sandstone formations about 2 miles from the Live Oak Campground entrance. "Drive, hike to the top and check out the observation deck. Go rock climbing or bouldering in Rock City," suggests Derek B., highlighting this distinctive geological feature.
Watch for wildlife at dusk: Dawn and dusk offer prime wildlife viewing opportunities in the area's preserves. At Morgan Territory Regional Preserve, camping feels "very off grid" according to Tyler S., while Michael S. advises visitors to "Beware wild boars are active at dawn and dusk" when exploring trails.
What campers like
Summit views: Juniper Campground at Mount Diablo provides exceptional vantage points. "It is absolutely worth it for the views of the east bay, and on a clear day, all the way to SF and the pacific. Truly one of the best camping views I've had," says Blake H., though he notes "they lock you in at sunset" requiring campers to call the fire department to exit after dark.
Convenient Bay Area access: Many campgrounds offer proximity to urban amenities while maintaining a natural setting. Anthony Chabot Regional Park is described by Amanda P. as an "amazing urban get-away" where "the eucalyptus groves make the air smell wonderful, and there is so much wildlife to see (deer, turkeys, owls, etc.)."
Clean facilities: Campers frequently mention well-maintained amenities as a highlight. Jay L. notes that at Mount Diablo's Juniper Campground, "Bathrooms: near JC Campsite#24 - clean with toilet cover and toilet paper" and the site has "plentiful" water spouts and trash/recycling bins.
What you should know
Weather fluctuations: Mount Diablo experiences significant temperature variations and strong winds, especially at higher elevations. "No matter how hot it is you'll never be able to escape the howling winds at night. Good tent stakes and warm gear is a must," warns Mike C.
Winding mountain roads: Access to several campgrounds requires navigating steep, narrow roads with limited guardrails. Blake H. advises about Mount Diablo, "plan for a 45 minute drive from town to the top, longer if you are doing it on a weekend when you'll be waiting to pass cyclists (be very careful, do not pass on blind corners, this is a cycling destination)."
Limited water availability: Some campgrounds have restricted water services. Blake H. mentions at Mount Diablo "Water is off, probably forever as CA will be in perpetual drought, so plan for that as well."
Recreational water warnings: Brannan Island State Recreation Area offers water access, but Ryan W. cautions about Lake Chabot: "The warm waters of Lake Chabot was beautiful and tempting as a siren, but don't touch it, or let your dog touch it...It is toxic. It will not make you a Ninja Turtle."
Tips for camping with families
Select sites with privacy: For families wanting space, choose carefully at campgrounds like Anthony Chabot. "The sites are fairly close to each other, which matters because one of the other campers is right next to mine and doesn't understand basic camp etiquettes," notes Ryan W., suggesting site selection makes a difference.
Consider temperature timing: Summer heat can be intense in Clayton area campgrounds. Sarah F. shares about Mount Diablo: "We went during the summer and it was very hot. The camp ground did not have much shade. We ended up taking a long hike around 4-5 pm when it started to cool food down."
Look for wildlife viewing opportunities: Many local campgrounds offer excellent wildlife spotting for children. At Briones Regional Park, Cococounty L. notes there are "Lots of opportunities for horse riders in area" along with pet-friendly trails.
Secure food properly: Wildlife encounters require proper precautions. Haley C. advises visitors to Mount Diablo: "Make sure that you lock up all food at night as the wildlife is very present and will take advantage of left out food." Jay L. adds, "If sitting around picnic table at night, make sure snacks are not out on picnic table, but kept in lap. Raccoon was not shy about jumping on inactive stove top."
Tips from RVers
Road conditions: The approach to pet friendly camping near Clayton, California often involves challenging roads. At Rio Viento RV Park, Kelly N. notes the "road to get into the park is rough but take your time, it's worth the drive" to reach the "beautiful, quiet clean dog friendly park" with "large brick sites."
Site selection for privacy: Despite proximity to other campsites, strategic selection can improve experience. At Skyline Wilderness Park, Moriah M. explains, "The campground is zero frills - you pull into a gravel lot and you're about 12 feet from your neighbors. The plus is friendly staff, amazing views, easy hookups, FREE showers and absolutely beautiful hikes that start right outside your door."
Check service availability: Internet connectivity varies significantly between campgrounds. Moriah M. reports at Skyline Wilderness Park, "My fiancée and I both work remotely using hotspots on Verizon, and found no trouble at all. Data speeds wavered between 10 - 25 mbps depending on where we were on the property, but we could video conference and stream with no issues."
