I doubt you would ever get a woodlot tour as a draw for your lodge. I think with so many organizations today having "forest demonstrations" or "walks through the woods", you really don't have to go far to see good sustainable forestry or new ways of gleaning forest products from the forest. These organizations include, the local colleges, the local industries, and the ever growing homestead organizations. They also typically have multiple demonstrations, such as horse-logging, tractor logging, and mechanical harvesting, so people can see a wide variety of harvesting methods, not just your method.
At the same time, as beautiful as the Canadian Rockies are (I have been there numerous times), there is far more interest in seeing such stuff where you live. That is, I would care very little about how, why and where Douglas Fir grows since it is not a wood I use, or even have near me. I would be much more interested in the wood species, how they are harvested, why they are harvested and what they are used for in my local area.
That being said, you do have a big woodlot and since its there, for the people that are drawn to your lodge for other reasons, you could easily set up a self-guided tour. Me and the ex-wife were in the Great North Woods and stumbled upon a self-guided logging demonstration up there. The local paper company placed signs and kiosks I guess you would call them. They had trails through the woods, and every few acres they harvested in a different manner, (clear cut, shelter wood, thinning, pre-commercial thinning, etc) so people could read about what they were seeing, why they did it,and what the benefits were. That was kind of cool, but I was a logger and interested in that stuff. You could do something very similar and then would not have to be there on every tour and get bored of saying the same thing to a new group of people.
Another idea you could do, is do a once or twice a year forestry weekend where you bring in other methods of logging like horse logging, cable skidding, mechanical harvesting and tractor logging. Even if you don't have the stuff, you probably know people in the industry that do use that sort of thing. It might be worth setting something up. As is, big machinery brings in people. maybe you have a friend with a 635 TigerCat that can just park his machine at the lodge for the weekend. People like to look at big iron.
While you are having this weekend event, throw in a few Stihl Timber Sports type events like the two man cross cut saw competition, or the ax throwing thing. A place by me puts on an exhibition like that every weekend during the summer for tourists. It has enough draw to keep the place open during the weekend for tourist season.
My only other thought is to work the history angle of logging. Many people like history and will drive a ways to see historical logging stuff. Myself, I have driven up to Lenard's Woods, a place that is rebuilt as an old 1790's logging mill and that is kind of cool. They do a twice a year weekend thing to keep the place running and do okay,though its more of a living history museum then anything else.
Those are a few thoughts I have. Maybe it helps, but as a woodworker/logger in a similar situation as you (large woodlot owner) I gotta say, most people today really don't care about logging and what we have to do to get wood out of the woods.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
