Flatirons Golf Course has a long and illustrious history as Boulder's premier golf club. Architect William H. Tucker was commissioned by the members of the Boulder Country Club, located at 28th and Iris, to design the course in 1933. Five years later, with the help of President Roosevelt's WPA (Works Progress Administration) program.

Many players have teed off on the fairways at Flatirons, including Boulder resident and golf guru George Hoos, who worked as a caddy at the club during World War II. Hoos recalls what is now the front nine being fenced off and closed for play in order to provide cattle a grazing area to aid in the war effort.

Today over 50,000 rounds are played per year at Flatirons Golf Course and over 1,000,000 rounds total since 1986 when the City of Boulder Parks and Recreation Department took over operations.
