Having set our sites on Jasper in September we now wonder if there is any snowmobiling in the area in the winter. Perhaps traveling from lodge to lodge?

One can do snowmobiling in Kananaskis Country, to the southeast of Banff National Park, and in the Golden, BC area, to the west of Yoho National Park.

However, snowmobiling is not allowed in the national parks themselves.

The "tn" in your name made me think you were Tennessee. If that's the case, the province of Quebec would be a closer winter destination for you. I did a Google search for SNOWMOBILE + MONT TREMBLANT, and this website came up. It mentions a snowmobile ride to a rustic lodge where you then have dinner.

But I have never been to Mont Tremblant myself, so I'm not talking from personal experience.

Snowmobiling in Jasper in September?
Wrong on so many counts.
As Judy states, not in a national park, ever, unless you want to make a long term relationship with a guy called 'bubba'.
September is the mating season for elk, moose, bear etc. A time for quiet hikes and animal voyeuerism.

If I understood tnmikey's post, he was not confusing September with winter. If he made a mistake in expressing himself, it was in mentioning September, since I don't think it was relevant to his question (if I've read it correctly).

Ahh. Judy I reread the OP and see where, if a comma was placed after the word September, snowmobiling in winter could be an option to vacationing in September.
Pedantic enough?
