*Contra Loma‘s 780 acres include an 80-acre reservoir for year-round fishing and a lifeguarded swim lagoon for summertime swimming. Enjoy these attractions along with year-round hiking, biking, and nature study at this Contra Costa County oasis.

This hike goes along the top of Contra Loma Dam for a scenic jaunt along the west shore of Contra Loma Reservoir from Antioch Community Park to Contra Loma Regional Park. It continues south into Black Diamond Mine Regional Preserve for a short out & back on Stewartville Trail before exiting the park grounds. The last three miles goes around the city streets for a coffee stop at Starbucks followed by a short stretch on the Delta de Anza Trail.

Begin this hike from Antioch Community Park; head west along the pathway towards Contra Loma Regional Park.

At the trail junction-turn left followed by an immediate right at the park information board. The gravel road travels west along Contra Loma Dam with wonderful views of the reservoir.

West Shore Trail winds around the shoreline of the lake.

Continue on West Shore Trail; the path leads you through the swim lagoon, park concession and picnic areas to the bridge at Loma Island.

Cross the bridge for a jaunt around the island.

Continue along the paved path towards Contra Loma Blvd-cross Contra Loma onto Frederickson Trail.

Frederickson Trail runs parallel to Contra Loma Blvd as it heads southward towards parking lot off the park entrance at Frederickson Ln.

Enter through the trail gate-go straight onto StewartvilleTrail at Black Diamond Mines Regional Preserve.

At the Contra Loma Trail junction: go straight to stay on Stewartville Trail. The broad gravel fire road continues on a gentle grade through the beautiful rolling hills.

Continue through the next trail gate-the trail winds up around the hill to the turn-around point at Ridge Trail junction.

Reverse your way down the hill and head back towards the parking lot at Frederickson Ln.

Turn right onto Frederickson Ln; the sidewalk leads eastward past the Black Diamond Canyon subdivision. The road comes to a T at Golf Course Rd-turn left and head north on Golf Course Rd; the road runs along the east edge of Lone Tree Golf Course and the Antioch Municipal Reservoir to Lone Tree Way. Cross Lone Tree Way onto Bluerock Dr; make your way through Bluerock Center for a coffee/tea snack stop at Starbucks.

Exit Bluerock Center back to Lone Tree Way; continue north on Lone Tree to James Donlon Blvd. Head west on James Donlon Blvd to the Delta de Anza Trail; the trail leads you back to Antioch Community Park.

This is a good post-rainy day hike around Contra Loma Reservoir and Black Diamond Mines-a good portion of the route being on paved trails and sidewalks. It also includes a warm-up stop at Starbucks. Being outdoors is always a good alternative to couch surfing!
