Get the traboule map from the visitor center (long line, be patient, my helper didn't prefer to speak English). Then, if you walk slowly and pay attention to the street signs (posted on the buildings on the corners), you can find all the ones listed on the map. I did it alone, and it took me about 3 hours with a cafe stop included. (Note: I walk fast and am good with maps.) The mistake I made was assuming most were in the Old City; most were in the Rousse area across the river, in the silk makers district. Take a bus or Metro to the Rousse area and then walk down (as the area is hilly) towards Vieux Lyon. There were a few plaques along the way with arrows that were helpful. I didn't know about them until I was on my trek. Maybe there is a map from the tourist center that just outlines those. That would have been really helpful so I wouldn't have been so dependent on my tourist map of traboules. I am so glad I explored these areas looking for traboules. It enabled me to understand and picture the history better. There also are some significant WW2 areas along the way marked with plaques.
