Route 17 (Japanese: １７番道路Route 17) is a route in northeast Kalos, connecting Dendemille Town and Anistar City. The route is also known as Mamoswine Road (Japanese: マンムーロードMammoo Road).
Due to constant snowstorms in the area, most of this route is covered in snow so thick that it is completely inaccessible by foot. Any person who wishes to travel through the route must ride a rental Mamoswine in order to do so. With the massive Pokémon, not only can the player plow through the snow with ease, but they can also be used to crush big boulders blocking certain parts of the route. In these certain parts, narrow paths have been plowed into the snow, allowing them to be accessed without the need of riding a Mamoswine.
Route 17 appeared in Over the Mountain of Snow!, where Ash and his friends rented a pair of Mamoswine in order to travel through the snowy mountain route on their way to Anistar City. During their journey through the route, they encountered an Abomasnow and a sick Snover, which they helped to recover before continuing onwards.
