The Town of Granby is the Statutory Town that is the most populous municipality in Grand County, Colorado, United States.[1] The town population was 2,079 at the 2020 United States Census.[4] Granby is situated along U.S. Highway 40 in the Middle Park basin, and it is about 85 miles (137 km) northwest of Denver and 14 miles (23 km) southwest of Rocky Mountain National Park.


The town was founded in 1904 along the route of the Denver, Northwestern & Pacific Railway and was incorporated one year later. It was named after Granby Hillyer,[7] a Denver lawyer who later served as the United States Attorney for that city's district.

Many Granby and Grand County residents are descended from pioneer settlers who arrived before the country was fully surveyed. Early families established themselves under the Homestead Act of 1862, which allowed easy access to land to those who would inhabit and improve upon the territory.

Since the turn of the century, families have contended for prime ranch land. The Hudlers and Cooks are descended from original homesteaders.[8] Their waning ranch once covered approximately 20,000 acres (81 km2) and was rich in cattle and hay.

Bulldozer rampage[edit]

Marvin Heemeyer was a local auto muffler shop owner had multiple zoning and disputes and sewage disputes with the town.[9] As a result, on June 4, 2004, Heemeyer went on a rampage through town, driving a modified bulldozer.[10] Several buildings were damaged, including a bank, a hardware store, the concrete company, a utility service center, the town hall, the police department, and a former mayor's home, all involved in Heemeyer's business having been destroyed.[11] The rampage lasted 2 hours and 7 minutes, ending when the bulldozer got stuck attempting to go through the alleyway of Gambles Hardware Store.[12] Heemeyer then committed suicide with a handgun. No other deaths occurred, but an estimated $7 million in damage was done.[13]


Granby sits at 7,935 feet (2,419 m) above sea level in the valley of the Fraser River, 2 miles (3 km) east of its mouth at the Colorado River. It is located in eastern Grand County in an area subject to average annual rainfall of 12+14 inches and annual snowfall of more than 128 inches (3,300 mm).

U.S. Route 40 passes through the center of town as Agate Avenue, leading south and east over Berthoud Pass to the Denver area, west 10 miles (16 km) to Hot Sulphur Springs, the Grand County seat. Kremmling is 27 miles (43 km) to the west on US 40. U.S. Route 34 intersects US 40 on the west side of Granby and leads northeast into Rocky Mountain National Park, crossing the mountains as Trail Ridge Road and reaching Estes Park 60 miles (97 km) northeast of Granby.

At the 2020 United States Census, the town had a total area of 8,116 acres (32.845 km2), all of it land.[4]
