One of our favorite parts of Lyon was the traboules or "secret passageways" in Vieux Lyon. We were…read moreonly in Lyon for a couple of days and no guided tours were available in English so we opted for a walking audio tour which included Vieux Lyon and Croix-Rousse area. We only did the Vieux Lyon walking tour but if we had more time, would def have done Croix-Rousse as well.
Traboules are secret passageways that lead you from one street to another....in the old days, this allowed tradesmen to move textiles. Our walking tour took us through a few traboules and it was kind of fun trying to find the entrance to the traboules. From what we gathered, the traboules are in private buildings but since they are tourist attractions, many of the traboules are still open and tourists are allowed to walk through them. Some of the traboules lead past courtyards and allow you to see old Lyon buildings from a completely different perspective. Super awesome.
This is the walking tour we took. We had to carry around big audiosets which was pretty cheesy but walking through the traboules made it all worth it.
