May be a dumb question. But do you do glacier tours in the summer?
Only glacier tour I’m aware of in the summer is the Athabasca Glacier tour. They drive you onto the glacier via bus, you get walk around on it and bottle some glacier water. If you’re an adventurer, try Yamnuska Adventures where you can do a 1 week intro to mountaineering course where you get to run rope teams, don crampons and walk on glaciers and climb mountains.
