At the point where Route 9 becomes Route 10, a northerly path heads toward the river, as well as a narrow strip of land along the northern tip of Route 10 which is fenced off from the rest of the route. From this strip, Trainers whose Pokémon possess the ability to use Surf out of battleRBYGSCFRLGHGSS or have learnt the Secret Technique Sea SkimPE can Surf/Sea Skim east along the river, then south past the remaining portion of the northern half of Route 10 (separated from the riverbank by a long fence) before turning west north of the Rock Tunnel's southern portal and making landfall just southeast of the building.
There is a lone Trainer located on the beachfront southwest of the Power Plant.
In Generation III, the Power Plant has a back door, allowing exiting the Power Plant immediately after battling Zapdos; due to a ledge, it can only be accessed from the inside.
Northern segment
Just east of the path leading to the river is the only patch of grass on Route 10. The main path of the route runs along the southern edge of the grass, turning south near the river. Directly south of the patch and east of the north portal of the Rock Tunnel is a Pokémon Center, one of only two in the region that is found outside of a populated area (the Center on Route 3 near Mt. Moon is the other). The building is separated from the Rock Tunnel by a string of shrubs and cuttable trees. Trainers whose Pokémon can use Cut out of battleRBYGSCFRLGHGSS or have learnt the Secret Technique Chop DownPE can use Cut/Chop Down to bypass one of the four trees, or travel around the blockade, taking on a Trainer at the southern end of the blockade.
From the Trainer, the route returns north, following the west side of the blockade. The path juts west, then east to avoid a fence before reaching the Rock Tunnel's north entrance.
The south portion of Route 10 acts much like a North American traffic circle in that movement is restricted in a counterclockwise motion around a large mound in the middle of the route. From the south entrance of the Rock Tunnel, the route turns west, then south, passing two Trainers and hopping a ledge before encountering a third Trainer. Route 10 then turns east to meet a three-way intersection. The south path at this fork leads to Lavender while the east path continues to the east before curving north, traversing a pair of ledges via openings, and returning west to the Rock Tunnel's southern portal.

Special encounters
Generation IV
A Zapdos appears here after obtaining 16 Badges. If defeated or run from, it respawns after entering the Hall of Fame.
Trainers with a telephone symbol by their names will give their Pokégear number to the player, and may call or be called for a rematch with higher-level Pokémon.

Route 10 is in two segments, the northern and southern. Rock Tunnel connects the two halves together. To the south is the Kanto Power Plant, where many Electric-type Pokémon and Zapdos can be found.
Generation II
With the renovation and reopening of the Power Plant, the Electric-type Pokémon that once inhabited it have moved into a new grassy patch located nearby.
The amount of space between the southernmost point of the northern segment and the north portal of the Rock Tunnel was reduced by half. To compensate, the Pokémon Center was moved three paces south. The tree barricade between the Center and the Rock Tunnel was also removed. Additionally, the northern corner with the patch of grass now belongs to Route 9. Trainers now enter Route 10 around halfway of passing the Pokémon Center. The southern segment of Route 10 was largely untouched, except for the removal of a Trainer and the relocation of another.
As a whole, the route was reduced significantly in size, as was the Power Plant itself. The Power Plant is taller in Generation I, but shorter and wider in Generation II.
Generations III
Route 10 in this Generation is almost identical to Generation I, but a few changes are present. The fence south of the Pokémon Center is larger and goes from east to west in Generation III. The Power Plant is redesigned, and the tree in the east part of Lavender section is removed. The hills are taller, and the Power Plant now has a west exit with a hill after it.
Generation IV
The north half of the route is very similar to that of Generation II save for the enlarged tall grass and that the Power Plant uses the same design of FireRed and LeafGreen. The southern half of the route changes drastically, hills are added to give a more in-depth feel to the route, and the two ledges in the east are smaller and closer to each other. The inverse "L"-shaped hill is changed and now it's shaped like a square. A Strength boulder is placed left of the hill. TM69 (Rock Polish) is located behind it.
Generation VII
The route is very similar to its appearance in Generation III, with only minor changes. More depth and height variation has been added as a result of the 3D graphics. The number of small trees to the right of the Rock Tunnel's entrance has been reduced to two, and the western exit of the Power Plant is no longer present, making it more similar to Generation I.
Route 10 appeared in a flashback in Lapras Lazily, where Blue told Yellow about his encounter with Elite Four member Agathatwo years earier. He had been surfing on Route 10 when he came across a wildLapras, which he caught in order to add its data to his Pokédex. A Jr. Trainer named Evan had then showed up, telling Blue that he had been trying to catch the same Lapras for weeks now. Although Blue had refused to give him the Lapras, he had still chosen to help Evan after he had told him how his Haunter had disappeared into the abandoned Power Plant. Inside the Power Plant, the two Trainers had come across Agatha, who proved to be an extremely powerful opponent. Eventually, however, their teamwork had allowed them to retrieve Evan's stolen Haunter and drive Agatha away. As a sign of gratitude for his help, Blue had given Evan the Lapras he had wanted.
Trivia
The fence and the tree barricade
The tree barricade mentioned above is very similar to the fence with the trees between the east tall grass and the entrance to this route in Route 9 in Generation IV.
A Hiker in this route, upon being defeated, will start laughing to himself before claiming that he actually got "hay-fever" and sneezing. In the original Japanese versions, however, the Hiker instead said that he is laughing because of some wild mushrooms he ate earlier.
In the Generation II games, there is unused Fly data for Route 10.
