The WDR Directory of Directories categorizes and lists directories of various sorts, including a selection of niche directories. There is no charge for suggesting a directory, but we supply the description.
I've added a category in our niche section for camps and campgrounds, which may include summer camps, religious camps, RV parks, and campgrounds, but not military camps or political parties. Only directories and directory resources are accepted in WDR Directory of Directories. We list the sites that list the sites, but we don't list the sites.
