Diglett's Tunnel (Japanese: ディグダトンネルDigda Tunnel) is a location on Akala Island in Alola, connecting to Heahea City in the north and Route 9 in the south.
Dugtrio can sometimes be seen traversing inaccessible rocky portions of the cave.
Diglett's Tunnel has an upper and lower level separated by stairs. A ledge also separates the upper and lower level on the eastern side of the Tunnel; another ledge separates the western part of the upper level from the rest near the stairs. Near the staircase on the lower level, the player can use Tauros Charge to access a narrow section of the Tunnel, which contains a Fire Stone.
