The village of Allenspark began to grow when summer people bought land and built cabins from around 1900 to 1920. Many people came up the South St. Vrain canyon from Longmont, and a number came from as far away as Kansas and Oklahoma in that initial burst. The greater Allenspark area extends beyond the village to include the small communities of Ferncliff, Longs Peak, Meeker Park, Peaceful Valley, Raymond, and Riverside, and is defined by the boundaries of the Allenspark Fire Protection District.
