The best MTB trails around Oakley

Newport Drive is a nice quiet road with a bike lane, a nice change from the otherwise often shoulderless roads in this area. It passes by Discovery Bay, which is a charming, gated community that also has a public area. If you need a break, it's a good place to stop before heading back onto the highway.

Located in the Black Diamond Mines Regional Park, the Old Homestead Loop climbs a dirt road up the ridge. While hiking along the trail, you can watch grazing cows and once you reach the top, be prepared for picturesque views of the surrounding hills and lush greenery.

This barred tunnel was once a bustling entrance to the Star Mine, one of the most active coal mines in the area, providing a livelihood for many families. The rusted bars that now block the entrance are a stark reminder of the mine's past glory and the hard work that went into extracting coal from deep beneath the earth's surface.

This trail is a great alternate route from Ridge Trail to Stewartville Trail, with stunning views from the top of the hill. Plenty of cows call this area home and are not shy about the boundaries of the path, making it muddy and uneven if you visit after wet weather. It connects with the North Portal Trail, giving endless options to explore more riding trails in this beautiful preserve.

This short loop trail provides a steady, periodically steep climb on a dirt road that is sometimes rough in places due to the stomping of the many grazing cows in the area, especially after wet weather. There are fantastic views from the ridge top and a quick descent back to the start. This trail is connected to several others in the park, making it perfect as an add-on for an extended ride.

The Stewartville Trail starts just south of the parking lot and runs through the preserve from east to west, linking the former Somersville and Stewartville mining towns. The route gradually climbs through a small, beautiful valley and can be ridden in either direction, but clockwise is recommended for the best ride. The trail offers excellent views in all directions, with Rose Hill Cemetery visible in the distance while looking west, Sand Creek Valley to the east, and Mount Diablo to the south.

The only plot of waterfront land not blocked by fenced residences. Private, so also not a public access to the waterfront.

This multi-use pathway runs alongside Marsh Creek, passing through vast, bountiful farmlands. It is a paved trail stretching about 6.5 miles from Big Break, where the Delta shores meet the waves, to Creekside Park in Brentwood. Along the trail, you'll find many community parks and greenbelts, which are great for taking a break and escaping the summer heat.
