Safest? They are all safe for you and your rig in that part of the world. Most direct?- From W. Glacier - come back west to Whitefish. Then US 93 north (number stays the same in BC) and cross at Roosville. Stay on 93 all the way to Radium Hot springs then turn N.E (still 93)thru Kootenay National Park until it crosses into Alberta/ Banff National Park and on to #1 (Trans Canada Highway - TCH) at Castle Mountain junction. From there east to town of Banff, west to Lake Louise etc. Your choice there depending on where you want to go and what to see? (PM me if you like on some of those things - details. That is my home country!)
