Tent campsites near Brentwood, California offer diverse overnight options with varying levels of accessibility and amenities. The region experiences hot, dry summers with temperatures often exceeding 90°F from June through September, while winter months bring cooler conditions with occasional rainfall. Most primitive camping areas in the surrounding regional preserves require campers to bring their own water supply, as natural sources are unreliable during dry seasons.
What to do
Explore volcanic formations: At Sibley Volcanic Regional Preserve, visitors can hike the Volcanic Trail along a former quarry haul road that features a self-guided tour. The preserve sits on an actual volcano, making it a unique geological site just outside the urban area. "San Francisco East Bay residents actually have a volcano in their backyard at Sibley Volcanic Regional Preserve," notes camper Elliott B.
Fish the Delta: Delta Bay RV Resort provides access to prime fishing spots along the Sacramento-San Joaquin Delta waterways. "Spent the night at my usual fishing spot and had a great time. Staff is friendly and food is good," reports Brandon L. The resort offers both shoreline fishing and boat launch access for more serious anglers.
Mountain biking: Las Trampas Regional Wilderness features challenging terrain for mountain bikers with significant elevation changes. The park's trail system requires good physical conditioning due to steep climbs. Most trails are designated multi-use, allowing bikes on wider fire roads while restricting access on narrow-gauge paths.
What campers like
Wildlife encounters: At Juniper Campground, campers frequently report hearing and seeing local wildlife. "Heard coyotes howling night and day which was neat. No raccoons. Saw some lizards," reports Brittney L. Hawk's Nest campsite in Sunol Regional Wilderness similarly offers ridge-top camping with opportunities to spot native birds.
Primitive camping experience: Morgan Territory Regional Preserve offers a backcountry camping experience that feels remote despite being close to urban areas. "Feels very off grid. Camp experience was smooth and the sun was shining," reports Tyler S. The preserve's limited facilities contribute to a more authentic outdoor experience.
Swimming opportunities: Reinhardt Redwood Regional Park and nearby Tilden Regional Park offer swimming options during warmer months. "Tilden offers a lake in the middle to swim in and fish," notes Nicholas M. These swimming areas provide welcome relief during hot summer conditions when temperatures regularly exceed 100°F.
What you should know
Summer heat warnings: Mount Diablo's Juniper Campground experiences extreme summer temperatures that can make camping uncomfortable without proper preparation. "Insanely hot in the summer, I would recommend not going in July like we did. It was 104° or something and I was just drenching my clothes in water to stay cool," warns Ben W.
Food storage challenges: Wildlife activity requires proper food storage at most campsites. According to Ben W. at Juniper Campground, "They have food lockers, not bear lockers, and ours was broken one time so have a solid backup plan, the raccoons are very intelligent and they come out at night so be prepared for that."
Limited facilities: At Las Trampas Regional Wilderness, the campground offers minimal amenities. Stuart K. describes it as having "5-6 stone picnic tables, a water fountain, only a single locker to place your food (so first-come, first served!) and a double-mounted grill." Most backcountry sites in the region have similar constraints.
Tips for camping with families
Bring extra water containers: Most camping areas near Brentwood have limited or unreliable water sources, especially in summer. At Sunol, one camper notes, "The sites are primitive and the water source questionable and unreliable. I hiked in all the water I needed." Plan for at least one gallon per person per day during hot weather.
Consider weekday visits: Weekday camping offers a quieter experience with better site selection. Sibley Volcanic Regional Preserve's small backcountry site can accommodate "a maximum of 15 campers (although this would be super cramped in my opinion, unless it a bunch of small kids)," according to Elliott B.
Visit educational features: Sunol Regional Wilderness offers creek exploration opportunities at an area known as Little Yosemite. "I have never camped here but hiked many trails," shares Erica K. The nearby Tilden Park Little Farm allows children to interact with farm animals when taking a break from camping.
Tips from RVers
Low clearance warnings: Briones Regional Park has some challenging access points for larger vehicles. "A few low spots. Cleared 12' barely with minor scrapes. Good parking and turn around," reports Cococounty L. Most camping areas near Brentwood have limited RV accessibility.
Consider tiny house options: For those seeking more comfort than traditional tent camping, Delta Bay RV Resort offers unique accommodations. "They have a lot of cute tiny houses in this campground. You can bring your own tiny house, or rent one for the weekend," explains Del B M. These provide an alternative camping experience with more amenities than tent sites.
