Red & Blue Route 20

Swimmers and rock formations dot the sea lane from Fuchsia City out to the Seafoam Islands, thick with drifting Tentacool.

Route 20 is in Kanto, with Cinnabar Island to the west. In the story you arrive from Route 19 to the east and continue through its entrance to Seafoam Islands.

ROUTE 20 MAP

Surf carries you the whole way along the sea lane between Cinnabar Island and the Seafoam Islands, threading past the rock outcrops that break up the channel.

Route 20 Guide

  • Yes. Each version locks away a handful of route species. Ekans, Oddish, Mankey, and Growlithe stay in Red, while Sandshrew, Bellsprout, Meowth, and Vulpix belong to Blue, with Scyther and Pinsir split the same way. Trading with the other version is the only way to fill those gaps.

  • Three rods, three givers. A fisherman in Vermilion City hands over the Old Rod, which only ever hooks Magikarp. The Good Rod comes from a fishing fan in Fuchsia City and adds Poliwag, Goldeen, and other common catches. The Super Rod, waiting on Route 12, reaches the rod-only rarities listed here.
