Open all year round, Maple Tree Campground offers the chance to spend the night in one of their unique tree cottages or treehouses. The cottages are insulated and come with mattresses, whereas the tree houses are more rustic; they don't come with mattresses, and they're not insulated for use in the winter. There are also 12 wooded tent sites and several large field sites suitable for groups of up to 60 people, but RVs cannot be accommodated. All sites come with fire rings, grills, and picnic tables, and sites must be booked for at least two nights on weekends.
