I'm in central Alberta, about a 3 hour drive from Saskatchewan River Crossing, and a little bit more to Banff. I've spent a lot of time throughout my life in and around the Banff area.
My father and I are thinking of doing a ride from Nordegg to SRC this weekend.
BTW - if you are planning a 3 day tour from Jasper to Banff this year, while you are in Banff, go soon! You are already running the risk of snow. Nordegg had snow last weekend, in fact. I'd say that Thanksgiving (the weekend of October 8-10th) would be about the last weekend I'd want to do that tour ... unless some very unusual heatwave comes through. Also keep in mind that after the Thanksgiving weekend, a lot of stuff will be closed, and may not reopen until the ski season starts, or spring.
Have you cycled the Lake Minnewanka loop yet ... that's a nice one. How about out to Johnson's Canyon, Castle Junction, or Lake Louise on the old 1A (Bow Valley Parkway)?
