Learn More About Living in Boulder County


Boulder County was one of the original 17 counties established in 1861 in the area known as the Territory of Colorado.  The county acquired its name as a result of the burdensome amount of boulders in the creek which made gold prospecting operations in the area difficult.   Captain Thomas Aikins led the first group of gold prospectors and settlers into the area in 1858.  They encountered Chief Niwot, leader of the Southern Arapaho people who hunted and lived in the area.  Despite the prospecting party's attempt to warm the Chief up to their presence in the valley with gifts of food and goods,  Niwot ordered them out of the area.  Aikins did not comply and the city of Boulder was established in 1859 as well as Gold Hill, which was the first town in which gold was discovered in Colorado.  Interactions between the native and the prospectors oscillated between tolerant and hostile as it became clear that Chief Niwot's vision, which is known as Niwot's Curse or the Curse of the Boulder Valley, was now a reality..."People seeing the beauty of this valley will want to stay, and they staying will be the undoing of the beauty."  


Boulder County is 740 square miles in area and is bordered on the west by the Rocky Mountains.  It contains the cities of Boulder, Lafayette, Longmont, and Louisville as well as the towns of Erie, Jamestown, Lyons, Nederland, Superior, and Ward.  Some of the more popular census-designated places within the County include Eldorado Springs, Gunbarrel, Niwot, and Hygiene. 

Boulder County is known for its beautiful landscape and access to amazing outdoor activities.  There are five national protected areas within the region: Arapaho National Forest, Roosevelt National Forest, Indian Peaks Wilderness, James Peak Wilderness, and a portion of Rocky Mountain National Park.  Eldorado Canyon State Park is a remarkable area located south of the city of Boulder and is protected by the state.
