Route 120 begins as an east-west route, carrying on the alignment of Fortree City to its west. The route, bordered by a small canyon to the south and a forest to the north, continues east, passing a Trainer before reaching the first area of grass on the route. By trekking through the grass at the westernmost point of the patch, Trainers can descend a flight of stairs to access a small ledge on the shore of the water inside the canyon. From this point, Trainers can Surf across the water to reach the Scorched Slab, a partially flooded cave.
Returning to the main path of the route, Route 120 runs along the northern edge of the grass patch before turning south through the patch. Gabby and Ty are often found near the point where the route turns south. At the southern edge of the patch, Bird Keeper Robert waits to battle. Near the Trainer, Route 120 curves to the west and crosses the canyon on a long bridge.
On the other side of the bridge, the route curves to the south, then to the east, as it enters a rainy, puddle-filled area of the route containing three Trainers. At the easternmost point of this segment is a path leading to a loamy soil patch blocked by a Cut-able tree. Directly south of the third Trainer, the route enters a maze of grass. Here, Bicyclists are forced to navigate the maze, occupied by two Trainers and a Nugget. However, Trainers that elect to walk can cut through the grass and head directly southeast to continue along the route. At the southern corners of the maze are a pair of ledges that regulate access to and from the maze between the two forks of Route 120 created by a small pond in the middle of the road. Heading south, Trainers must hop the ledge in the southeast corner to reach the second bridge on the route south of the ledge. After crossing the structure, Route 120 comes to a three-way intersection. The northern path can be utilized by northbound travelers only, as a well-placed ledge prohibits access to this intersection from the north. Likewise, the path across the bridge is limited to southbound travelers. Heading south from the intersection, Route 120 continues.
Roughly ten paces south of the intersection, a small set of stairs leads to the shore of the small pond. Near the stairs is Bug Maniac Brandon, who will make his Masquerain hold SilverPowder (and, thus, the item can be stolen using Thief or an equivalent move) after being defeated five times. To his south is another patch of grass off to the east of the route as well as another three-way intersection. The main path of Route 120 continues east to Route 121. The left branch leads to the Ancient Tomb.

To the southwest of the intersection is a woman who freely gives out rare Berries. Near her is a loamy soil patch containing three Pecha Berry plants. To her north is a flight of stairs leading to an upper area of the route.
In this area, there is another loamy soil patch containing four different varieties of Berries, as well as a small pond with Full Heal on the opposite shore. Continuing north, however, the path trudges through a patch of grass before ascending a set of stairs leading to a plateau on the route. In the center of the plateau is the Ancient Tomb.
