From its southern terminus at Route 27, Route 26 continues east on a bridge over a body of water for eight paces before turning north, where a Trainer waits. About fifteen paces north of the northward turn, Route 26 makes landfall for the first time. At this point, the route turns to the northeast for a short distance, passing through several grassy areas filled with wild Pokémon, after which another Trainer waits at a three-way intersection. To the west is the southern exit of a southbound-only express route, which occupies the west side of Route 26 and can be used to quickly return to Route 27, the Tohjo Falls, and Johto. To the north are more grass patches and the main path of Route 26 as it continues on.
Free of grass for the remainder of the route, the road continues north for another twenty paces before intersecting the northern terminus of the express path. North of this intersection is a rest stop similar to that on Route 111 in Hoenn. Next to this house is an Ice Berry treeGSC or a Blu ApricornHGSS.
Route 26 turns northwest from the rest stop, passing another Trainer before returning northward. Twenty-five paces ahead, Cooltrainer GavenGSC / Ace Trainer GavenHGSS awaits on the west bank of a small pond located east of the route. Upon defeating him, he will offer to exchange numbers in the Pokégear for future rematches.
Continuing towards the Pokémon League Reception Gate, the road turns northeast ahead of another southbound-only express path. The route straightens out, taking on a northern alignment as it passes another Trainer hidden in an alcove and Cooltrainer BethGSC / Ace Trainer JamieHGSS at the northern terminus of both the express path and Route 26. She will also offer to exchange numbers after battling.
Just north of her is the south entrance to the Pokémon League Reception Gate as well as the signpost that gives the gate its formal name.
Northern express path
Southwest of the Pokémon League Reception Gate is a series of ledges enclosed by the eastern side of a large mountain (which comprises the western edge of Route 26) and a series of hills between the express path and the main path of the route. Together, the ledges make a southbound-only path that can be used to quickly travel down Route 26. A Max Elixir is also located amongst the ledges. The path rejoins Route 26 northwest of a small pond.
Southern express path
The southern express path begins south of the rest stop at an intersection with Route 26. After heading west, the path enters a large area of grass, which encompasses most of the northern portion of the path. Eight paces to the west, the express route turns south for another ten paces before circling east around a house, which happens to be the home of the Week Siblings, although none of them are present. A note on the table inside reveals the location of every sibling and the days of the week on which they will appear.
South of the house, the path hops over a ledge, effectively making the path southbound-only. Here, it meets the southern entrance to the express path. Traveling east along the entrance is prohibited by a ledge that separates the entrance from the path.
Continuing south of the one-way intersection, the path hops over two more ledges before reaching the body of water that encompasses most of the southern terminus. Trainers can either surf east across the water to the bridge or turn to the west and continue along the express path, which continues for a short distance before forcing Trainers to hop a ledge onto Route 27.
This route is very grassy yet with several rocky outcroppings in the east and west and tiny rocks along the road. The sea rocks follow the shape of the bridge and trees are in the south borders of the route. There is also a portion of sea at the northeastern end of the route.
Although it is located in Kanto, the route uses only Johto tile sets as opposed to Kanto's.
In this generation, a large amount of rocky hills are added along the road, making the route less grassy and more like a mountain. While the hills are of an altitude of one tile in the original games, they have an altitude of thirteen rocky outcroppings in the remakes: two hills are placed after the two southern ledges, one hill is added north of the rest house and four hills are placed along the road, the others are only for decoration and they are placed in the borders of the route. There is also an island in the southeast, and now the player can surf under the bridges. The trees in the west section and the sea portion in the northeast are also removed.
Unlike in Generation II, the tile sets instead use Kanto-style trees and a mix of Johto-style and Kanto-style rocks.
After entering the Hall of Fame and boarding the S.S. Aqua, the battle music changes from the Johto style to the Kanto style. This change was not present in the original Pokémon Gold and Silver nor in Pokémon Crystal. This also occurs in the Tohjo Falls, Victory Road, Routes 27 and 28.
Unlike on Routes 27 and 28, the player is able to fly to both Kanto and Johto from this route (as well as from the Indigo Plateau). In Generation II, the player cannot fly to Johto from anywhere in Kanto, which includes Routes 26 to 28 and the Indigo Plateau.
