Black Hawk is a home rule city located in Gilpin County, Colorado, United States.

It was a mining settlement founded in 1859 during the Pike's Peak Gold Rush and is now a part of the Denver-Aurora-Lakewood, CO Metropolitan Statistical Area and the Front Range Urban Corridor.

Black Hawk is located adjacent to Central City, another historic mining settlement in Gregory Gulch.

The two cities form the federally designated Central City/Black Hawk National Historic District.

The area flourished during the mining boom of the late 19th century following the construction of mills and a railroad link to Golden.

The town declined during the 20th century but has been revived in recent years after the 1991 establishment of casino gambling following a statewide initiative in 1990.

[13] Nathaniel P. Hill built Colorado's first successful ore smelter in Black Hawk in 1868.

Hill's smelter could recover gold from the sulfide ores, an achievement that saved hardrock mining in Black Hawk, Central City, and Idaho Springs from ruin.

Black Hawk's advantageous location on North Clear Creek made it the center of ore processing for the area, and it became known as the "City of Mills".

Development of the area down Clear Creek from the historic Black Hawk townsite lining State Highway 119 has flourished.

The ban was prompted by a surge in traffic following the change in maximum casino betting limits from $5 to $100.

[23][24] Bicycle advocacy groups challenged the bike ban, with the case ultimately going to the Colorado Supreme Court.
