Welcome to Jefferson County

Jefferson County has something for everyone; from rivers for floating and fishing, to hiking and climbing in the Elkhorn Mountain range, and a large motorized and non-motorized trail system. Boulder, High Ore and Basin are home to several radon health mines, ghost towns, Boulder Hot Springs and Whitehall hosts Frontier Days every July. The county fair is held in Boulder in August. Jefferson County abounds with natural resources and its economy is based around these, including production agriculture, wood products and mining.
