Kanto Route 21/Route description

From Pallet, the route begins as a small channel of water. South of the town, an outcrop of land on the route's east side holds the only grassy area on any water route in Pokémon history up until Generation IV. Past the grassy area, the mainland terminates and the route widens significantly in size.

South of this point, the look of the route varies greatly by Generation. In Generation I, there are two small bridges containing two Trainers each spread out along the route. Five other Trainers are also found along the route. In Generation II, the bridges remain but only one Trainer is found on one of the bridges. Two more Trainers are located in the water. Generation III replaced the bridges with sandy islands and added five additional islands as well. Trainers can be found on four of the islands, as well as in five locations in the water, making a total of nine Trainers.

In every Generation, the route runs directly north-south in the water, reaching its southern terminus at Cinnabar near the southernmost Trainer.
