Wikivoyage:Extraregion

Extra region pages are pages that run parallel to the accepted hierarchy. They reference articles of cities and regions that belong to other regions. These pages are useful when overlapping regions are known by a number of different names.

They may just be a list of other locations but can also contain specific text for that region that does not fit well into any other region or city.

Examples include:
 * geographical areas that span political boundaries, like Appalachia, the Andes or Lake Tai
 * region names in fairly wide use that do not fit our hierarchy, like Western New York
 * administrative regions that may be important to officials but do not matter much to travellers, for example Mimaropa in the Philippines or Shanghai/Pudong New Area

Pages are tagged at the bottom with the extraregion template. Displaying:

Articles are added to Category:Extra regions.

Note that an extraregion should typically not have any subregions or destinations which use it in their IsPartOf template. When changing an existing region article to an extraregion, it's a good idea to check the destinations listed and change them to the appropriate hierarchical parent, as appropriate. Rare exceptions can be made when the child article is itself a valid extraregion, such as the case where the Great Lakes includes Lake Ontario.

In some cases a region is better described as a travel topic than as an extraregion.
