From Yakima and the Tri-Cities(about an hour):

Take exit 63 (Sunnyside/Outlook) off of I-82. From the exit ramp follow the signs toward Outlook. Turn left (west) onto Yakima Valley Highway. At Outlook turn right (north) onto South Outlook Road, which after 1 block becomes North Outlook Road. Go 3 miles North on N.Outlook Road - crossing Van Belle, Independence Roads - and the little bridge over the irrigation canal. Immediately turn right (east) onto Chaffee Road - continue for about 1.9 miles following the signs for Steppe Cellars. At the top of the hill you will find us in the Quonset Hut.
