Gold Hill is an unincorporated community and a census-designated place (CDP) located in and governed by Boulder County, Colorado, United States.

[4] Gold Hill is located to the northwest of Boulder, perched on a mountainside above Left Hand Canyon at an elevation of 8,300 feet.

All of these roads are susceptible to heavy snows during the winter, which at times render Gold Hill inaccessible to vehicles not equipped with chains or four wheel drive.

Gold Hill is part of unincorporated Boulder County, and while it does not have a municipal government, it does have an active town meeting with elected officials.

Word quickly spread among miners in the region, prompting a flood of new arrivals and the establishment of Gold Hill as the first permanent mining camp in present-day Colorado.

By autumn, a quartz stamp mill was erected at the base of the hill, the first such piece of equipment in the region, one that had been transported by ox cart westward over the Great Plains.

By 1861, the year of the organization of the Colorado Territory, the surface deposits of gold in the vicinity of the town were largely played out, resulting in a temporary exodus of prospectors and a population decrease.

The town was somewhat revived later that year by the construction of the Hill smelter at nearby Black Hawk, allowing the treatment of lower-grade ores.
