A tourist center has been built opposite the glacier for the benefit of visitors. Facilities available include a restaurant, cafeteria, a free interpretive center with displays about how glaciers form etc, and a small amount of overnight accommodation for guests.
From the center, you can book a 1 hr 30 minute Snocoach ride onto the glacier. Snocoaches depart every 15 minutes during the tourist season as long as weather permits, and cost roughly $30Canadian per person. This will take you right up onto the glacier itself so you can get a close-up view, and you can actually get out of the coach and walk on the ice.
During the summer months, specially trained guides lead short guided walks on the ice, but that is only possible for a few months of the year when there is no snow-cover on the ice to hide the crevasses. At other times they keep a large circle ploughed clear of snow, and you have to stay in this 'safe zone' to ensure you do not find a hidden cravasse the hard way.
Be warned - even though you can walk right up to the base of the glacier from the road, this is NOT a safe thing to do. Snow-covered crevasses are invisible until you fall into them, and many people have died of hypothermia due to falls.
