Sky River Equestrian Center offers a rare combination of professional-grade equestrian infrastructure, exceptional scale, and a spectacular Pacific Northwest setting. Located behind the gates of Sky River Estates, the property features 460+ feet of Skykomish River frontage, sweeping mountain views, and easy access to the Mann Road horse trail system just off the property. At the heart of this exceptional property is an impressive 50+ stall facility designed for serious equestrian use. The main dual isle-way barn includes wash racks, grooming and shoeing bays, expansive hay loft, heated tack rooms, laundry and lounge. A covered 100' x 216' arena with viewing deck provides year-round riding, while the attached 80' x 180' mirrored dressage arena houses a 50' round pen and brand-new Centaur Equineciser hot walker. A newly installed 150' x 300' outdoor arena further expands the training capabilities. Fenced and cross-fenced grass pastures, 12 all-weather paddocks, and heated automatic waterers throughout the design supports efficient year-round operation. Attached living quarters include a 3-bedroom, 2-bath ground-floor residence plus a separate 1-bedroom, 1-bath loft apartment. An extraordinary opportunity for a private equestrian estate, training operation, or professional horse facility in one of Washington's most striking settings and outside of the flood zone.
