From its north end at the maze of Route 13, the path heads south along the east edge of a long treeline. After a distance of roughly 20 paces, there is a gap in the treeline, allowing Trainers who can use Cut or Chop Down to remove a small tree and to pass through. Just past this point is the first Trainer on the route.
The line of trees continues for another 15 paces before terminating near another Trainer, uniting the paths west and east of the trees into one. Directly south of the treeline at this point are a pair of Trainers.
Route 14 turns west here as the two paths become separated once again. The path west of the trees, now the upper path of the route, climbs onto a hill that overlooks the entire length of Route 15. This path, however, is only accessible by using Cut to remove a tree blocking the entrance. The eastern path, now the lower path, becomes the main path of Route 15.
Western tree path
Heading north from the point where the two paths merge, the western path encounters four Bikers (Punk Guys in Generation VII) near the gap in the treeline. North of the Bikers is a grassy area containing wild Pokémon.
Only a few changes are present between these generations. Most aesthetic features have been enhanced. Trees have become bigger and flowers have been added. Also, the road is more visible. The signpost is sightly moved to the north and trees are added around the route.
In Generation II, the Bikers were removed from the route and, additionally, the number of Trainers was reduced to three, with a Trainer now located at every extent of the route save the northern side.
A Pokémon collector can also be found wandering the grass in Generation II, looking for a Chansey, for which she will exchange her Aerodactyl. This trade came to be in this generation due to the loss of the Pokémon Lab on Cinnabar Island, which was the only the only way to receive an Aerodactyl in Generation I.
The layout is similar to other generations. A hill is added in the east road, as well as six windmills. On the sea to the right, Suicune will appear and then flee right when Eusine arrives. The trees placed in this hill are separated by one tile from each another. Also, the number of Trainers is increased to eight. Three Schoolboys and a Teacher are present in the west path where the Bikers were placed in Generations I and III.
The woman looking for a Chansey will not ask for a trade. Instead, simply talking to her with a Chansey in the party will earn the player a Lucky Punch.
