Route to Banff from Montana

There's also Gold Springs and Milk River campgrounds just north of The Sweetgrass/Coutts border crossing. Milk River is a small campground and we usually stayed there for one night while on the home ward bound part of our semi annual trip out west.Tried to get into the Gold Springs campground on a Labour day weekend but it was full up. Being retired we forgot about the holiday weekend as we're on holidays permanently. Waterton National Park can't be recommended enough by us. We always stayed at the Waterton Springs Campground for a couple of weeks and it's a mile or so north of the Park gates. You could go north from there to Pincher Creek and grab #3 hwy from there west bound to Hwy 22(Cowboy Trail) and take that right up to Hwy #2(trans Canada) to Banff.Hwy 22 is in the foothills and it's a nice drive and good road.There can be heavy duty winds apparently but I guess we were lucky because we never experienced any...there.
