Route 41 consists of the Whirl Islands and their surrounding area. The entrances to the four islands are inaccessible due to whirlpools until the Trainer has the HMWhirlpool to traverse them. Three of the four islands yield valuable Pokémon and items, but if the player has the Silver Wing in their Bag, Lugia can be found through the northeast portal. This route is also home to Mantine, which is only found in this area in Pokémon Gold, Crystal and HeartGold.
A Trainer may Surf around the Islands in any way they please; however, directly south of the southernmost of the Whirl Islands, the route turns due west towards Cianwood City.
