Commanding 165 acres across multiple legal parcels with approximately three-quarters of a mile of private Clear Lake shoreline, The Hacienda at Ceago is a rare California lakefront and agricultural estate at approximately 1,400 feet in elevation. Offering an unusual arrival experience for San Francisco Bay Area and Silicon Valley guests, the estate features a dedicated helicopter landing area and an approximately 350-foot private pier with floating docks to accommodate direct seaplane access and a double boat lift. Approaching the approximately 28,000 square feet of structures, the drive is lined with century-old Sevillano olive trees, approximately 2,000 Italian cypress, palms, vineyards, and Blue Weber agave. Defined by California Mission and Hacienda architecture, the estate features terracotta tile roofs, stucco-finished masonry towers, massive timber ceilings, hand-forged ironwork, and interconnected courtyards. The residences provide 14 bedrooms, 15 full baths, and 3 half baths across the principal residence, Farm House, four private Guest Casitas, Caretaker's House, and Worker's Casita. Designed to host approximately 500 guests, the grounds unfold through original Tasting Rooms, the lakefront Terraza, El Taller, the fireplace-centered Pomo Room, and the Galera Courtyard featuring a timber-beamed outdoor kitchen. Amenities include six full kitchens, two kitchenettes, commercial restrooms, extensive laundry facilities, two executive offices, exercise and massage rooms, plus the Cantina connecting the Hacienda to the working agricultural landscape. At the water's edge, La Palapa offers a sandy private beach, full bar, and outdoor grilling, positioned near the Boat House & Bar. The 22.35-acre estate vineyard features 11.6 acres of Sauvignon Blanc and 10.75 acres of Cabernet Sauvignon, complemented by younger olive groves for oil, lavender distilled on-site into essential oil and hydrosol, and agave maturing for future Ceago spirits.
