Eldora (pronounced el-DOH-ruh), previously known as “Eldorado” then “El-Dora”, then Eldora or Camp Eldorado, and is still called Happy Valley. is a census-designated place (CDP) in Southwest Boulder County, Colorado. The population was 142 at the 2010 census. The CDP of Eldora is more commonly referred to as a small town or village.
Eldora is located within the Roosevelt National Forest, and is primarily a rural, densely forested, and sparsely populated area. Eldora is tucked into the valley carved by Middle Boulder Creek, from which there are views up toward the alpine ski runs of Eldora Mountain Resort. A one-time gold camp, Eldora was a shipping point for the Caribou silver mine in nearby Nederland, CO. At present, Eldora is characterized by small cabins, a sprinkling of vacation homes, and several long-shuttered mercantiles.
It peaked at the turn of the century, but experienced a devastating wildfire in 1899. With much of its timber lost, lumber that was vital to the mining construction was in short supply. The 21st century has experienced renewed interest in Eldora mining, with hopes of reopening the Mogul Tunnel Mine on Spencer Mountain.
Points of interest near Eldora include the Eldora Mountain Resort, Eldora Historic District, and Indian Peaks Wilderness. Eldora Historic District has been listed on the U.S. National Register of Historic Places since 1989. The area is home to an abundance of wilderness and wildlife, including animals such as mountain lions, black bears, coyotes, red foxes, mule deer, elk, bobcats, and much more.
