June 11, 2025, Native American Trails and East Shore Trailhead

Contra Loma Park forms a very large protected green space south of Contra Costa Canal and Antioch Community Park. It preserves some Trails named for the native American groups that once lived and thrived in this watershed, part of which might now be flooded by the Contra Loma Reservoir

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.
