Yes! Root Glacier is one of the most easily accessible glaciers in Alaska. The trail to the toe of the glacier is only 2 miles. Once at the glacier, all you need is a pair of microspikes or crampons. The glacier is icy and slippery so it is not recommended to walk on it without spikes. Avoid walking near the edges of the glacier as the ice is unstable and can give way to swift running water. For more on glacier hiking safety you can read up here. It is 14 miles from the foot of the glacier to the Stairway Icefall, so there is a ton to explore. The icefall, the second largest in the world, is a steep part of the glacier that looks like a waterfall. Viewing it on the glacier is stunning but it can also be viewed from the footbridge on a clear day.
