I went twice to the catacombs, the first time i gave up, because the lines to buy the tickets was very, very huge. Yesterday i return earlier from work and tried again and there nos just one guy on the line (very good).
I am staying near the metro 9, so i just need to go from line9 to line6 until the "Denfert Rochereau" station.
It is nice to know a little bit about the history of the catacombs and why they build that.
It is a nice place to visit once in your life.
