The Town of Kremmling is a Statutory Town in Grand County, Colorado, United States. The town population was 1,509 at the 2020 United States Census. The town sits along the upper Colorado River in the lower arid section of Middle Park between Byers Canyon and Gore Canyon. The town was founded in 1881 during the Colorado Silver Boom days, but the lack of mineral resources in the nearby mountains made the town grow very slowly in the early days.
