Nestled in a high mountain meadow in the Elkhorn Mountains southeast of Helena, Montana, the 4-R Ranch & Cattle Co. is a 900-acre working cattle ranch that has welcomed guests since the property was first established in 1917 as the Gustafson Ranch. The current owners, Tom and Patti Russ, transformed parts of the cattle operation into a wedding destination after Cassidy Russ and Chase Cunningham became the first couple married at the ranch in 2011. Outdoor weddings and events are hosted from the last weekend of June through the first weekend of September. Ceremonies take place in the Grove — an outdoor sanctuary with a redwood pergola set among the evergreens — while receptions and gatherings can be staged in the Hay Field. Couples receive exclusive use of the ranch from Friday afternoon through Sunday at noon, with support from an on-site wedding coordinator. The restored Ranch House is available as a gathering place for the bridal party or as a mountain retreat for guests.

Kleffner Ranch is a historic event venue in East Helena, Montana, occupying a property that dates to 1887, when William C. Child established White Face Ranch as a purebred Hereford cattle operation. The barn's stonework — laid by Italian masons in the 1880s — has been carefully preserved, and the property has since been recognized as a Montana historic site. Today, the ranch offers multiple event spaces across a scenic property near the Helena Valley. The centerpiece Barn is a 27,000-square-foot structure whose main floor accommodates up to 500 guests for weddings, galas, and large celebrations. The Ballroom on the second floor of the stone octagonal mansion suits more intimate gatherings — rehearsal dinners, anniversaries, and corporate meetings. The heated and air-conditioned Banquet Hall is well suited to events of up to 160 guests, while The Pavilion seats up to 168 and features a dance floor, bar, and gas fireplace. The Grove, an outdoor area shaded by towering cottonwoods along Prickly Pear Creek, offers a natural setting for open-air ceremonies and receptions.
