Old Mill Farm

Old Mill Farm is a distinctive barn wedding venue set on 34 acres of working farmland in Onalaska, Washington, conveniently located between Portland and Seattle. The property offers a relaxed countryside setting for couples and organisers planning weddings, receptions, rehearsal gatherings and other private celebrations.

The venue is available for exclusive weekend hire from Friday to Sunday, giving hosts time to prepare, welcome suppliers, enjoy a rehearsal and celebrate without the pressure of a single-day booking. The restored barn provides a warm, characterful setting for ceremonies, meals and evening parties, while the surrounding farm offers plenty of space for outdoor photographs, informal gatherings and memorable moments with guests.

Bookings can accommodate up to 299 guests. The venue package includes a substantial collection of tables and chairs, a built-in bar with beer taps and keg cooling, commercial refrigeration, large screens for slideshows, sinks, waste facilities and ample field parking, including reserved accessible spaces. A private, air-conditioned bridal suite is also provided, with a kitchen, bathroom, shower, washing machine and dryer for the wedding party’s convenience.

Outside, organisers can make use of the fire circle, grape vines, café lighting and Adirondack chairs. The property’s natural surroundings create an attractive backdrop for ceremonies and photography, while the barn offers a practical base for dining and entertainment. Old Mill Farm works with a limited number of event dates each year, helping preserve an intimate and personal atmosphere. Tours are available by appointment, and the team welcomes celebrations for couples from all backgrounds.
