Visit the Union Pacific Dining Lodge website for more information on renting the venue.


The beautiful Union Pacific Dining Lodge was designed by famed architect Gilbert Stanley Underwood. It was built in 1925 to serve passengers traveling to Yellowstone via the Union Pacific Railroad. Underwood was known for his rustic-style architecture, defined as a style that used native materials in proper scale, avoided rigid, straight lines, gave the feeling of having been crafted by pioneer craftsmen with limited tools, and achieved a connection to natural surroundings and to the past. Underwood’s other accomplishments include the famed Ahwahnee Lodge in Yosemite National Park, the Timberline Lodge in Oregon, and the Old Faithful Lodge in Yellowstone.

Little has been changed since this building was constructed, leaving a large, rustic space perfect for many types of events including weddings, quinceaneras, family reunions, corporate events, etc.
