Rock Tunnel
The Rock Tunnel is a naturally formed underground tunnel. The cave serves to connect the northern and southern segments of Route 10
Geography
The Rock Tunnel is a mostly empty cave. Since it has not been developed, it is pitch black inside. A light of some sort is needed for travelers to find their way, so it is recommended that Pokémon Trainers bring along a Pokémon that can use Flash outside of battle.
Rock Tunnel is the only alternative route to Lavender Town, as the two other routes have been rendered inaccessible by a slumbering Snorlax and the Saffron City gatekeepers. The cave has two separate floors, both of which are roughly the same size. There are no Trainers within the cave.
Route 10 leads from Cerulean City to Rock Tunnel. At the northern entrance of the cave is a convenient Pokémon Center. The roof of the Kanto Power Plant can also be seen from here. The southern entrance exits onto the remainder of Route 10, leading to Lavender Town.
