Route 34

37 Pokémon can be caught at Route 34 in Johto — highlighted on the map below.

Trainer battles line Route 34, the straightforward path from Ilex Forest to Goldenrod City in central Johto. Its main draw is the region's Day Care, operated by an elderly couple mere steps from the city, where up to two Pokémon can be left to level up for a fee or a compatible pair can produce an Egg. Surf opens a hidden area holding three Ace Trainer sisters named Irene, Jenn, and Kate; in HeartGold and SoulSilver, two of them team up for a Double Battle.
