How do you get out of rock tunnel on FireRed?

Answer 1

The fastest way to escape from any cave is to either use an escape rope that is an item that can be bought in shops or found. The other option is to use the TM move called Dig. That move can be found after you have battled the rocket member behind the house with the police officer in front of it. If you do not have any of these items you would need to go through the darkness (unless you have flash) to the exit.
