Located west of Ste. Genevieve off of Route 32, Hawn State Park is a pristine example of Missouri's eastern Ozark sandstone country. Located at the eastern edge of the St. Francois mountain range, this primitive park has some of the Missouri's most beautiful and significant landscapes. The 4,953 acre park is located in the LaMotte sandstone basin, an area of the state where exposures of sandstone create unusual landscapes.
The acidic soil of the area supports lush upland forests of shortleaf pine, Missouri’s only native pine tree, and hardwood stands of white oak, shagbark hickory, and red maple. In the spring the flowering azalea and dogwood trees provide a spectacular show.
A diverse selection of flora and fauna can be found in the park’s sandstone canyons and clear sand-bottom streams, many of which are unique to the area. The initial acreage of the park was donated in 1952 by Helen Coffer Hawn, a retired school teacher from nearby Ste. Genevieve.
