Pokémon FireRed and LeafGreen/Route 20

This route is confusingly divided by the Seafoam Islands in the center. If you're taking them on, beware that another one of the Legendary Birds resides there, as the game already hints you, if you've been looking at everything. Route 20 continues the connection between Fuchsia City and Cinnabar Island, although blocked in the middle by the islands.

Only Tentacool are found by surfing, so use repels on these waters not to be annoyed by the persistent repetitive encounters.
