Diglett’s Cave in Pokémon HeartGold and SoulSilver — Diglett’s Cave in HeartGold and SoulSilver

Diglett’s Cave is a long tunnel dug by Diglett, linking Route 2 south of Pewter City with Route 11 east of Vermilion City. In HGSS a sleeping Snorlax blocks the Vermilion end at first, so the cave becomes the main shortcut into western Kanto once it is awake. Brock also hangs around the northern entrance.
