No matter how you get here, you’ll be glad you did!
From San Francisco and the East Bay area, head east on Highway 4 past Pittsburg and Antioch. Go North across the Antioch Bridge (Highway 160). Follow Highway 160 North to Highway 12 and turn east onto Highway 12. Follow Highway 12 for approximately 3 miles. Turn Left at Jackson Slough Road and Right on Terminous Road. After one mile, turn left onto Oxbow Marina Drive. Follow the road up onto the levee and into Oxbow Marina.
Coming North from San Francisco Bay, fork South at Pittsburg. Follow the San Joaquin River East to the entrance of the Mokelumne River at the southeastern tip of Andrus Island. About 3 miles upstream, just after passing under the Highway 12 bridge, you’ll find the entrance to Georgiana Slough to port. The waterway narrows here, but there’s still plenty of water as you cruise a few more miles upriver to Ox Bow Marina.
