Located at the confluence of the Mississippi and Kaskaskia rivers, Fort Kaskaskia State Historic Site is an ideal place for campers along the Lewis & Clark National Historic Trail. Dating back to French settlements in the 1700s, Fort Kaskaskia later served as the site where, in 1803, the Corps of Discovery picked up an additional eleven men for its expedition. The Corps also took time to brush up on scientific readings around the region and gather supplies.

Today, visitors will find scenic overlooks of the Mississippi River and can visit the earthwork remains of Fort Kaskaskia. Garrison Hill Cemetery, established in 1891, is also within the site grounds. This special cemetery was established for the gravesites of early settlers whose original resting places were under threat from floodwaters in the late 19th century. The Mississippi River overlook includes nearby tables and a pavilion for picnics. At the bottom of the bluff is a path that takes visitors to the historic Pierre Menard Home, built around 1815. This well preserved and beautiful site is named in honor of its builder, Pierre Menard, who served in the Illinois legislature and was a fur trader and businessman.

For tent campers, there are both primitive and 32 electric-hookup campsites. Water is also available at select locations. Fire pits are located at each site. Two playgrounds are also available in the day-use area.
