We traveled with Cosmos Tours from Calgary to Vancouver and this was one of our stops. You get on a bus with special tires to ride up on top of the glacier. There was a guide on the bus who gave information about the glacier. When you get off the bus, they give you a paper drinking cup because there is a spot where pure water comes out of the glacier that is cool and drinkable. The area you are permitted to walk on is clearly marked out. We had plenty of time to walk around and see the iceberg.
