This route meanders along the flat scenic winding levee roads around the Sacramento Delta Region from Brannan and Tyler Islands to Andrus Island.

Begin this ride from Isleton and meander through the town’s residential neighborhood out to Jackson Blvd.

The road name changes to Jackson Slough Rd as it exits town through the expansive farmland and vineyards around Brannan Island.

Cross over Georgiana Slough onto Tyler Island Rd and head south along the east side of the waterway past the farmlands and waterfront homes around Oxbow Marina.

The levee road curves slightly east before traveling south, the terrain also changes from pavement to a super bumpy washboard gravel section as it cuts across the patchwork fields.

Tyler Island Rd turns eastward onto pavement where Georgiana Slough spills out onto the S Mokelumne River.

The pavement ends once again as it rolls around the island on a broad gravel road with expansive views of the rich fertile farmlands and gorgeous blue river for the next 4 miles.

The levee road returns onto pavement as it continues north along the delta cornfields and vineyards followed by another short section of gravel before coming to the road split at Race Track Rd.

The road continues past the scattered farmhouses and ranches before coming to a T junction at Isleton Rd.
