The Forest Preserve District of Will County’s Isle a la Cache Museum immerses visitors in the region’s cultural heritage and natural history. The free museum transports visitors back to the 18th century when “Illinois Country” was home to the fur trade. See how the two worlds of French voyageurs and the Potawatomi intertwined. Feel the softness of a beaver pelt, see canoes built out of birch bark and walk inside a wigwam. Venture outside to see a replica of a Native American longhouse or handle voyageur tools in Traders Cabin. All of this takes place on a beautiful 101-acre island preserve in the middle of the 2,400-acre Des Plaines River preservation system. Nature lovers can spot turtles basking on river banks and deer wading in the water. Bird-watchers will delight in seeing bald eagles and osprey circle overhead while vibrant warblers make the riverside forest come alive.
