I recommend the tour but not the bus. It was freezing cold during the 3-hour trip btw Montreal and Quebec giving us headaches. I requested several times to shut down the air conditioner but no response.
Absolutely astonishing tour. For less than 100$CAD, it was totally worth it. The places were beautiful, the time was appropriate for the activities, the food arranged by the guide was pretty good and the guide herself was very considerate with everyone, making it a memorable one. She was quite organized, , attentive, and clear with the activities. I highly recommend this tour.
