Route 4

23 Pokémon can be caught at Route 4 in Kanto — highlighted on the map below.

Route 4 runs across northern Kanto, divided by Mt. Moon into a western half adjoining Route 3 and an eastern half descending to Cerulean City. The western section holds one of only two Pokémon Centers in the region built outside a settlement, where a shady salesman offers a Magikarp for $500 with no refunds in Generations I, III, and VII. Despite the dubious deal, some players consider the early Magikarp worthwhile for raising a Gyarados ahead of schedule.
