Wonderful Tour!
Beth_K, Apr 2019
Lesley was Terrific! Very knowledgeable of the Massive Underground system. There were just two of us, plus Lesley. It was like having a private tour. She showed us the Main features. Plus she had photos of what things looked like prior to renovations. I loved going to the 360 Observatory to take stunning picture of Montreal and the Laurentian mountains. Thank you Lesley for a terrific tour! Beth

Excellent tour & tour guide!
Kayla_D, Dec 2019
My family was lucky enough to have Lesley as our guide on 2 tours while on our trip to Montreal! (Check out her Old Montreal walking tour if you haven’t already). She is incredibly knowledgeable and passionate about the history of Montreal. She really gave us a unique perspective of the underground city and it was a very interesting tour. My family loved both tours & Lesley!
RESO is Amazing

Our tour guide, Lesley Thompson from MTL Detours, was a very knowledgeable and personable tour guide. The history behind the underground is fascinating and you visit places you would never find or if you did you wouldn't realise where you were while having fun. Lesley also gave us ideas for other things to do in Montreal and places to eat, she is a very capable tour guide putting visitors first.
