By linking a couple of levee roads (closed to vehicles), hikers can fashion a six mile tour of the great grassland, as well as the willow- and cottonwood-lined San Joaquin River that winds slowly, in a series of sloughs and oxbows, through it.
The Highway 165 entrance to Great Valley Grasslands State Park will be closed until mid-February due to road construction on Highway 165. Please use the park entrance on State Route 140.
