River Run at Sun Valley Resort

River Run Lodge sits at the base of Bald Mountain, tucked between the slopes and the Big Wood River in Sun Valley, Idaho. Built from river rock and exposed log timbers, the lodge carries an alpine warmth that suits mountain weddings and private celebrations year-round. The main dining room accommodates up to 250 seated guests, while the full lodge — including its additional dining rooms and patio — opens to 600 for standing receptions. Floor-to-ceiling fireplaces, chandeliers, and expansive windows framing the mountain make the interiors as striking in winter as they are in summer. An outdoor ceremony lawn adds flexibility for warmer seasons. River Run Lodge is available year-round, with event timing adjusted around ski and summer operations. The resort's weddings team handles catering, venue coordination, and menu selection in-house, with china, flatware, glassware, and a dance floor included in the rental.
