I agree with Flyboy 320 about the route from Edmonton-Jasper-Kamloops as a good option. However, highway #3 from Osoyoos to Ft. McLeod, though a nice option, has four fairly major pulls over passes. There is a good pull right out of Osoyoos, then a second out of Christina Lake over to Castlegar. You can avoid the other two at Castelgar by going into Nelson, then over the Kootenay Lake ferry. If you choose to follow #3, there is a good pull out of Castlegar to Salmo, then the longest pull over the Salmo-Creston pass. The grades here are steady for up to 25 km. the steepest being as you near the top.
