Welcome to Keystone Ranch in the Evergreen Valley, a gated equestrian estate on nearly 16 private acres where rustic splendor meets refined living minutes from Olympia. Designed for serious equestrians, this exceptional property features a rare attached 9-stall barn with five covered paddocks, two uncovered paddocks, two enclosed stalls, oversized tack room, hot and cold wash rack, LED lighting, and additional space with potential for more stalls. Ride year-round in the 106' x 60' lighted arena, train in the 60' lighted round pen, or practice over the cross-country jumps. Twelve fenced and cross-fenced productive pastures with New Zealand and field fencing, three loafing sheds, gates, breezeway, and frost-free water stations throughout for ranch management. Approximately 2,324 feet of creek frontage, and a covered bird-watching retreat complete this remarkable ranch. The cabin-inspired home offers warm wood accents, a loft-style primary suite, two additional bedrooms, a dedicated office, bonus room, oversized laundry room, granite countertops, newer Bosch appliances, dual tankless water heaters, mini-splits, a new furnace and heat pump, fresh exterior paint, new flooring, and durable metal roofs on both the home and barn. Additional amenities include a fenced dog area, enclosed shop, detached garage, three covered parking structures, RV power hookup, and an owned 500-gallon propane tank. Potential for an ADU and possible subdivision (buyer to verify). No HOA or CCRs.
