Route 18 is in south eastern Unova, only accessible by surfing through Route 17's rapids. The main part of the route is taken up by a hilly island in the west. Some researchers believe that it once bordered the Desert Resort. On the center of the island is a house where your Pokémon can be healed if needed. Also in the house is a treasure hunter who will give you a Larvesta egg; and a man who buys Rare Bones, which the wild Dwebble in the area occasionally hold. After defeating Ghetsis at N's Castle, you'll find Rood of the Seven Sages here.
