Beulah is located at (38.075798,-104.986038) and lies within a valley bordered by the Wet Mountains to the west, Mt. Signal to the south and southeast, and a prominent ridge that forms the north through east sides of the valley. Elevations within the open valley itself range from about 6,150 to 7,100 feet (1,875 to 2,165 m.) Four creeks, North Creek, Middle Creek, Squirrel Creek, and South Creek flow through the valley. They all converge as they flow eastward; eventually combining into one at the valley's eastern end as the North St. Charles River, which flows into the St. Charles River southeast of Beulah and drains into the Arkansas River just west of Vineland.
