Spyrock Ranch is just north of Round Valley, which is often referred to as "Nature's Hideaway." Some 160 miles north of San Francisco, Round Valley is the largest area of flat land in Mendocino County. Noted for its picturesque landscapes and towering valley oaks, Round Valley is the western entrance to the Mendocino National Forest and Yolla Bolly Wilderness. A 3,300+/- foot paved and night-lighted runway provides easy access into the valley for private aircraft.

The ranch is located in Mendocino County, nine miles north of Dos Rios on the Eel River and 11 air miles northwest of Covelo in Round Valley. Travel to the Ranch is by county road north of Covelo, then through neighboring ranches on dirt roads, to the Ranch's eastern boundary line. Travel time from Covelo to the Ranch gate is about one hour.
