Outdoor Day Trips from Antioch for Groups

One reason groups choose Antioch is how close it is to open space. Within a short drive there are hills, a mountain, reservoirs and the waterways of the Delta. Here are the best outdoor day trips for a family or group staying in Antioch.

Black Diamond Mines Regional Preserve

On Antioch's southern edge, Black Diamond Mines covers rolling hills that were once home to coal mining towns. Today it has a network of trails through grassland and oak woodland, an old cemetery from the mining days and views over the Delta. The park has offered underground mine tours in some seasons, so check the park district's website before you go. The trails come in many lengths, which makes it a good choice for mixed groups.

Contra Loma Regional Park

Contra Loma is a reservoir park close to town. In summer its swim lagoon is a favorite with families, and the lake is used for fishing and paddling. Picnic areas can hold a large group, so it is easy to spend a relaxed afternoon here with a cooler and a ball.

Mount Diablo State Park

Mount Diablo rises above the East Bay and its summit view on a clear day stretches across much of Northern California. A road leads to the summit area, so grandparents and small children can enjoy the view while more active members of the group hike sections of the trails. Spring brings wildflowers. Check the state park's site for hours, fees and any closures.

The Delta

East and north of Antioch, the Sacramento-San Joaquin Delta is a maze of rivers and channels lined with small towns and marinas. A drive along the levee roads makes a slow, scenic half-day, with stops for lunch by the water. Some marinas rent boats; book ahead if you want to get on the water.

Brentwood farms

Strictly speaking this is agriculture rather than wilderness, but U-pick farms in Brentwood are a favorite outdoor outing in late spring and summer. Cherries come first, followed by other fruit through the season. Check each farm's picking calendar before you go.

Tips for a smooth outdoor day

• Start early in summer. Afternoons in eastern Contra Costa County can be very hot.
• Bring water and sun protection. Many trails have little shade.
• Check fees and parking. Some parks charge per vehicle, so carpooling saves money.
• Pack lunch at the house. A big kitchen makes it easy to prepare picnic food for the whole group.
• Agree on a meeting time. Groups often split by pace on the trail.

Where to stay

The six-bedroom Antioch House sleeps up to 15 and makes a comfortable base for all of these trips. For more on the area, see our Antioch and East Bay page, our guide to things to do in Antioch and ideas for family reunions.
