The road ascends in a huge contour up the mountain and, at that point, Route 227 ends and the exterior of Stark Mountain begins. In Pokémon Diamond and Pearl, a huge clearing opens up that contains a large patch of tall grass. The entrance to the interior of the mountain can be found to the west.

In Pokémon Platinum, the exterior is more complex and the path winds around pools of bubbling lava. It is darker and aesthetic features have been enhanced. The large patch of tall grass is still present, but it is not as big. By going northwest, an item can be found in an indented section of track. By traveling to the northeastern corner, a path will open up. By following it, the road will lead through two pools of smoking, bubbling lava around another bend to the entrance of the interior of the mountain.
