Diglett's Cave is a long tunnel dug by wild Diglett and Dugtrio in Kanto. The northern entrance is on Route 2, south of Pewter City, and the southern entrance is in Vermilion City near the Route 11 exit. The passage is famous for connecting these two routes. The cave is needed to complete the story as it is the only way to get to Pewter City while Route 19 is blocked off.
As a whole, the cave runs from the northwest to the southeast, passing under Celadon City, Route 7, and Route 6 as it progresses toward Vermilion City from Pewter City. There are no points of interest along the cave; however, the cave is the only location where wild Diglett and the rare Dugtrio are found in Kanto.
The usefulness of the cave as a connector route between Routes 2 and 11 has allowed Diglett's Cave to become one of the most important non-numbered routes in the Pokémon world. It is the only way to get to Pewter City before workers finish clearing the debris on Route 19
