The Town of Collbran is a Statutory Town in Mesa County, Colorado, United States. The town population was 708 at the 2010 United States Census. Collbran is a part of the Grand Junction, CO Metropolitan Statistical Area. The town is located east of Grand Junction along Plateau Creek, at the upper end of the small cattle ranching valley around the creek known as the Plateau Valley. The largest community in the valley, it serves a civic and economic center for the surrounding area, which is dependent not only ranching, but on pass-through tourism during the summer and autumn months. In the latter capacity, the town acts somewhat as a gateway to nearby Vega State Park and other recreational sites along the northeast side of the Grand Mesa via the Grand Mesa Scenic and Historic Byway.
