Byron Glacier
The mountains surrounding Portage Glacier are covered with smaller glaciers. A 1-mile hike off Byron Glacier Road—the trail begins about a mile south of Begich-Boggs Visitor Center—leads to the Byron Glacier overlook. The glacier is notable for its accessibility—this is one of the few places where you can hike onto a glacier from the road system. In summer, naturalists lead free weekly treks in search of microscopic ice worms.
