Situated amidst walnut orchards and along the scenic Sacramento River, one hour north of Sacramento, discover the multi-faceted 238.79-acre, Grand Island Ranch in Colusa County. As you make your way through the brick columns topped with pineapple, an ode to the ranchs hospitality and welcoming spirit, you are greeted by the grand entrance of the main home with a well-landscaped paved plaza. The main home is situated on a quiet two-acre corner of the property, providing a tranquil escape from the working ranch headquarters, which are located across a separate parcel. Living is easy at Grand Island Ranch. The main home boasts six bedrooms, four bathrooms across 4,628 square feet, offering ample space for family living and entertaining. Just a stones throw away, is the pool and chic pool house. An entertainers delight. Grand Island Ranchs agrarian roots run deep. With fertile Class II and III soils, solar-powered 100 HP irrigation well, and riparian rights to the Sacramento River, the property supports 180 acres of planted walnuts. Additionally, there are 10 acres of suitable land that could be cultivated for a crop other than walnuts. Beyond the agricultural value, this property offers a great recreational lifestyle. Over a mile of Sacramento River frontage is perfect for fishing, boating, and other water activities. The surrounding countryside also provides excellent hunting opportunities for wild turkeys, deer, dove, and pheasants. At the working ranch headquarters along the Sacramento River, there is a comfortable 2,461 square foot guest home with a pool, detached four-car garage, a 1,090 square foot three bedroom home suitable for caretaker home, and a 900 square foot two bedroom home used as an office. There are two large and functional workshops with large roll-up doors, cement floors, shelving, electricity provided by solar panels on the roof, and a lift. Two historical barns remind one of the rich agricultural traditions of Colusa County. Located in a prime location with easy access to nearby towns, parks, and wineries, this property offers the best of both worlds: a productive agricultural operation and a peaceful rural retreat. If youre seeking a unique opportunity to own a thriving walnut orchard and enjoy the beauty of the Sacramento River, Grand Island Ranch is an ideal choice.
