Rock Tunnel FireRed & LeafGreen · Dungeon

Rock Tunnel is the dark two-floor cave that links the northern part of Route 10 (reached from Route 9 out of Cerulean City) with the southern part that leads to Lavender Town. You pass through once on the way to Lavender, usually around the low-to-mid 20s, and every floor is packed with trainers. Without Flash you can only see a small circle around your character.

Tips
- Bring Flash (HM05) before you go in: the cave is pitch dark otherwise, and the Oak's aide in the Route 2 gatehouse hands it over once your Pokédex has ten species registered.
- Geodude and Zubat make up most encounters; Mankey and Machop are the useful finds, and Machop is a bit more common on 1F than on B1F.
- Onix is uncommon (5% on 1F, 10% on B1F) and any trainer here with Geodude or Onix is easy prey for a Water or Grass type.
- There are about fifteen trainers, mostly Hikers, Picnickers and PokéManiacs, so stock up on Potions and Repels (a Repel is also lying on 1F).
- Pick up the Pearl, Escape Rope and Repel on 1F and the Revive and Max Ether on B1F while you are working through the trainers.
