The ZIP Code of the Cascade Post Office is 80809.It was a resort town, with 3 hotels, from the 1880s to the 1920s. Tourists traveled through Ute Pass on the Colorado Midland Railway, experiencing scenic views of Cascade canon and its falls during their journey. Carriage tours brought tourists up Pikes Pike to its summit. Tourism fell when the Manitou and Pike's Peak Cog Railway opened in 1892, and tourists were about to travel to the summit of Pikes Peak through Manitou Springs.When visitors traveled by automobiles, beginning in the 1920s, they had different needs and came in smaller numbers than the previous decades. The Ute Pass region could no longer support large hotels and 2 of the 3 hotels in town were demolished by 1926. Eastholme, a small inn, has been foreclosed and is currently for sale. The Pikes Peak Highway entrance is at Cascade.
