About Idema Explorers Camp
The Idema Explorers Camp (IEC) at Ottawa Sands offers a unique overnight experience at the intersection of Lake Michigan and the Grand River in Ottawa County. The IEC features three treehouses, five yurts, and 10 tent pad sites. This project was made possible thanks to a $3.48 million gift from the Bill and Bea Idema Foundation.
All campers will have access to the 345-acre park along with its amenities. Visitors can explore the park’s existing trail systems and the neighboring parks of North Ottawa Dunes and P.J. Hoffmaster State Park. Campers can also enjoy Lake Michigan access at North Beach Park and partake in various water activities on the Grand River or Lake Michigan.
