Geography of South Park

South Park is located southwest of Denver and northwest of Colorado Springs. It is about 1000 square miles of grasslands and hills surrounded by mountain ranges and accessed by four main mountain passes: Kenosha Pass on US 285 in the northeast, Wilkerson Pass on US 24 in the southeast, Hoosier Pass on Colorado 9 in the northwest and Trout Creek Pass on US 24/285 in the west. In addition there are passes which are mostly accessible only by 4-wheel drive vehicles, and which are generally closed in the winter: Mosquito and Weston in the west and Boreas Pass in the north.

The mountains surrounding South Park are the source for the waters of the Middle Fork of the South Platte River, which flows south through SP, then east through Twelve Mile Canyon, then north and east to Denver and finally north to Nebraska where it joins the North Platte to form the Platte River.
