The Union Pacific Dining Lodge is a historic event center in West Yellowstone, Montana, built in 1925 and designed by architect Gilbert Stanley Underwood — the same architect behind the iconic Ahwahnee Hotel at Yosemite National Park. Constructed from native rhyolite stone and local timber, the building exemplifies the National Park Service rustic style: a soaring timber beam ceiling, floor-to-ceiling windows, and a massive arrowhead-shaped fireplace anchoring the main hall. Originally built to serve up to 350 Union Pacific Railroad passengers in a single seating, the lodge closed in 1960 when passenger rail service ended and later served as the West Yellowstone Public Library from 1981 to 2007. Today it operates exclusively as an event center hosting weddings, family reunions, corporate gatherings, and milestone celebrations. The Mammoth Room, the lodge's main hall at 6,600 square feet, accommodates up to 300 guests. The adjoining Firehole Room, with its own fireplace and historic bar, suits cocktail receptions and intimate events for up to 100 guests. The venue supplies tables, chairs, glassware, flatware, and audio equipment, and is wheelchair accessible.

The lodge serves as the social heart of the property, with a great room featuring a stone fireplace and bar and an adjacent dining room with mountain views.

Rainbow Ranch Lodge sits along the Gallatin River in Gallatin Gateway, Montana, within reach of Big Sky and Yellowstone National Park. The property traces its roots to the late 1800s, when early homesteaders first shaped the Gallatin Canyon corridor, and has operated as a guest lodge since the 1920s. After a 2008 fire, the current owners undertook a full renovation and repositioned the lodge as a mountain retreat with an emphasis on weddings and private events — now hosting 25 to 30 weddings each year. The lodge accommodates up to 150 guests at events set against the Spanish Peaks and the Gallatin River, with riverside ceremony sites and reception spaces alongside 21 rooms and suites for overnight accommodations. A dedicated wedding coordinator supports events from initial planning through day-of execution. The Wild Caddis restaurant, recognized by Wine Spectator and OpenTable, offers seasonal Montana cuisine built from local ingredients, with private dining rooms available for rehearsal dinners and intimate group gatherings.
