The weather in the high mountain passes can change rapidly at this time of year, the Banff town site has already seen a bit of snow. There is a long steep grade south of the Athabasca glacier so use your brakes sparingly. Slow down at the top and use the tow/haul mode to control your speed, snub the brakes occasionally to keep things out of the white knuckle range but don't ride them. Long steep grades are a fact of life here so drive accordingly. Fuel up in Jasper, the next opportunity is Field unless you are prepared to get gouged at Saskatchewan River Crossing.
Many campgrounds are closed for the year, you cannot stop in undesignated areas in the parks so govern your time accordingly. Golden has a nice one by the river if it is still open. Best to call ahead.
