"The Matanuska Glacier is one of the easiest to reach from Anchorage, and the largest one in the state accessible by car. The 229-acre recreation site is best for learning all about the science of glaciers. (You can also just go to a pullout on the highway if your goal is a quick photo before continuing on.) To trek out onto the glacier itself, you need to head off the Glenn Highway at mile 102 and onto private land, where you’ll pay a $30 access fee. It’s worth it! Area guide companies offer the chance for newbies to take their first steps onto a glacier or, even better, to do some ice climbing."
