Grannis Fishing Access Site is the only official public access point on the Shields River, located northeast of Livingston just east of Highway 89 and 4 miles north of Interstate 90.

The 1-acre site features a gravel parking lot and direct river access for wading anglers, though note that weapons discharge is prohibited year-round and caution is advised regarding hazardous trees on adjacent DNRC property from a 2013 fire.

The site is open year-round and does not offer developed facilities.
