Dårlig Ulv Stranden

Dårlig Ulv-Stranden — which, according to the non-Norwegian speaker, Rose Tyler, meant "Bad Wolf Bay" — was a bay fifty miles outside Bergen in Norway on the alternate Earth dubbed "Pete's World". It was notable for being the place where the Tenth Doctor and Rose said their first "final" farewells to each other. (DW: Doomsday) Rose would later call it the location of "the worst day of [her] life". (DW: Journey's End)

After the War in the Medusa Cascade, the Doctor took Rose back to Bad Wolf Bay with the Meta-Crisis Doctor and Jackie. The Meta-Crisis Doctor elected to stay with Rose. The two shared a kiss as the Doctor and Donna departed in the TARDIS. (DW: Journey's End)

Behind the scenes

 * To date, only the Dårlig Ulv-Stranden located on Pete's World has ever been seen or referenced; whether it also exists in the main Earth of the Doctor Who universe is unclear. According to Google Maps there is no Dårlig Ulv Stranden in Norway.
 * The beach was filmed in Southerndown beach, in South Wales, which was later used as the surface of Alfava Metraxis in DW: The Time of Angels/Flesh and Stone.

Lost in translation
Although a reasonable name from an artistic standpoint, Norwegian speakers have noted several real world difficulties with the name.
 * Despite actor pronunciation in the episodes featured, it is actually pronounced "Dorli Ulv-Stranden".
 * The adjective "dårlig" can be translated as "poor in quality" or "feeling bad; as in feeling sick", rather than the context the Bad Wolf entity entails. A better translation might have been "Slem ulv-bukten"
 * Strand actually means "beach" or "seacoast" not "bay".
 * A strictly literal translation of "Dårlig Ulv Stranden" might be "Poor wolf-beach".

However, the name given does have the virtue of being a double-pun. As the Doctor points out, "Dårlig" is phonetically similar to "Dalek", while "Stranden" refers to Rose's situation: stranded in a parallel universe.
