Great Valley Grasslands State Park
6 mile loop
The Great Central Valley is known nationally—even internationally—as one of the world’s most productive agricultural regions. It is not, however, known for its parks.
City-dwellers speeding along Interstate 5 or Highway 99 through the Central Valley often get the impression the region is one gigantic corporate farm, with every single acre under cultivation.
Yet some wild areas remain, reminders of days long gone when the deer and the antelope played on a vast grassland. A well-deserved pat on the back goes to the California Department of Parks and Recreation, whose Sacramento planners and ﬁeld personnel have worked for several decades to set aside some pre-tractor terrain. The agency has acquired parkland in both parts of the Central Valley—the Sacramento Valley to the north and the San Joaquin Valley to the south—and tried to emphasize the region’s unique natural attractions, as well as its special historic and cultural background.
One before-the-plow parcel well worth a visit is the new Great Grasslands State Park, located in the San Joaquin Valley some 25 miles west of Merced. A native bunchgrass prairie, vernal pools and a slow, lazy length of the San Joaquin River are highlights of the park. Great Grasslands seems even larger than its 2,700 acres because it’s bordered by state and federal wildlife refuges.
The remote park, a recent combination of two heretofore obscure state units known as San Luis Island and Fremont Ford State Recreation Area, is visited mostly by locals who come to ﬁsh for bass and catﬁsh from the banks and sand bars of the San Joaquin River.
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.
Directions to trailhead: From Interstate 5, 11 miles north of Santa Nella, take the Highway 140 exit. Drive 19 miles east to Highway 165. Travel 1.2 miles south on Highway 165 to the state park’s ﬁshing access on the San Joaquin River, then another 0.2 mile south of the San Joaquin River to a gate on the west side of the highway. The trail is the levee road beyond the gate.
The hike: Walk the levee, overlooking the San Joaquin River to the north and sweeping grassland to the south. A half mile out, observe the large (in springtime) vernal pool, frequented by ducks and migratory water¬fowl. One mile from the start is an unsigned junction. Head right, continu¬ing to parallel the San Joaquin. After another mile and a half, the levee road turns south, away from the San Joaquin, then a mile farther still, turns east. The levee gets lower, the grass gets higher, and the hiker soon feels wrapped in very special world where the silence is broken only by the rustling of the grass.
Four-and-a-half miles out, you reach a junction and bear left on a ﬂat gravel path back toward the San Joaquin River. After walking 0.5 mile, you reach this hike’s ﬁrst junction; bear right and retrace your steps a mile back to the trailhead.
