The alternative to this tour was a train that had to stop at the Canadian border but our bus tour led by Brian crossed the Cdn border into British Columbia and then further north into the Yukon. The bus is definitely the better choice. Brian was extremely knowledgeable and very flexible for photo opps, bio breaks, etc. We had lunch at Caribou Crossing, Yukon which had a very impressive wildlife museum, gift shop,and petting zoo. Breathtaking scenery throughout the trip, a desert dotted with evergreens, waterfalls, rockfalls, lakes, rugged mountains with mountain goats, - this tour had it all !
