Lulu City was a transient mining town in eastern Grand County, Colorado, in the Kawuneeche Valley in what is now Rocky Mountain National Park. The town appeared after silver was discovered in the area in 1879 by prospector Joe Shipler, and was built primarily by the Middle Park and Grand River Land Improvement Company in 1880. The company was backed by Benjamin F. Burnett of Fort Collins and Fort Collins rancher William Baker. The town was named after Burnett's daughter. By 1881 there were forty cabins and a number of business establishments. By this time it was apparent that the silver ore was of low grade, and that high transportation costs made mining in the area marginal, and the town began its decline. It was abandoned by 1885, except by Shipler, who lived there for thirty years.
