Idledale is a small mountain community in Jefferson County, Colorado, tucked into just over half a square mile of foothill terrain west of Denver. With 259 residents and 128 households, this isn't a sprawling suburb. It's a compact enclave where Highway 74 winds through and street names like Cold Springs Gulch Road and Grapevine Road follow the natural contours of the landscape.
The post office maintains 174 PO Boxes for 128 local households. That's a 1.36 adoption rate, meaning there are 36% more boxes than homes. This happens because Idledale serves surrounding properties and residents who don't have standard street delivery. USPS classifies this as a PO Box Only Delivery Zone, which means there's no alternative mail delivery available here.
Despite the PO Box classification, some street delivery does exist. One rural carrier route and one highway contract route serve 41 delivery points along the local roads. General Delivery is also available at the post office, a service typically offered in remote or transitional areas where residents need temporary mail access.
The community has a median age of 47.9 years and high educational attainment. About 66% of adults hold bachelor's degrees or higher. Median home values around $450,000 and per capita income of $67,871 indicate an affluent foothill community. Many residents work in transportation, warehousing, or utilities (154 workers), which likely includes commuters traveling via Highway 74 to Denver metro jobs. Another 52 work from home.
Idledale sits near Genesee and Indian Hills, part of the mountain corridor between Denver and the high country. It's close enough to the metro area (Genesee South is 0.3 miles away) but far enough up the foothills to maintain a distinct, rural character. The 91% white population and 19% Hispanic or Latino population make up most of the demographic profile. Only 6 children under 18 live here, suggesting a community of established professionals and empty nesters rather than young families.
