Why The Washington County Fairgrounds in Hillsboro? More central location for Willamette Valley and Southwest Washington llama owners. Only 15 miles from the heart of Downtown Portland, and aprox 25 miles to the Portland Airport. MANY more lodging and dinning options close by. Larger facility with more stalling options and the capacity for a show. Big, clean, open and attractive greenspaces. Lightrail and a Comfort Inn Hotel connected to the fairgrounds parking lot means that out of area visitors do not necessarily need to rent a car. The Hillsboro airport is also right across the street.
