I did this tour the end of May and it was fantastic!! James was our guide and chatted about the history of the area the whole way. We saw a caribou, and bear and 3 different spots. Each time he would pull the small bus over and make sure everyone got a picture. We stopped numerous places for photos. Getting across the border was no problem, just needed to show your passport. The ArriveCAN that we did initially to get into Vancouver sufficed. I thought I would miss the train, but I saw so much more. Highly recommend.
