Hello Lianne,
Agree with everything that's been said. I've booked the Canadian Rockies tour for 10 September this year and am really looking forward to it, it sounds fantastic!
If you want to know age range etc for a particular tour, click into the ask the editor section and post a message. I checked last month for the 10 September trip and at that time, there were 26 booked on the trip, 22 female/4 male with an age range between early 30s to mid 70s.
Hope you decide to take the plunge!
Kind regards
Ann
