Houghton County Airport (CMX) is the closest airport, about a 15 minute drive from Calumet, only serviced by United Airlines from Chicago. Marquette Sawyer Regional Airport (MQT), about a 2 hour drive to Calumet, serviced by United and Delta from Detroit, Chicago, and Minneapolis. MQT would be the better option if you are looking to get a rental car, CMX has a very limited supply.
We have multiple options listed under the travel tab of the website, but we would recommend the AmericInn, we have a room block that can only be utilized by calling (906)337-6463. The room block is only available for use until 30 days out.
