Fodor's Expert Review Mendenhall Glacier

Glaciers are abundant in Southeast Alaska, but only a very few are as accessible as Mendenhall Glacier. Alaska's most-visited drive-up glacier spans 12 miles and is fed by the massive Juneau Icefield. Like many other Alaska glaciers, it is retreating, losing more than 100 feet a year as huge chunks of ice calve into the small lake separating the glacier from the Mendenhall Visitor Center. The center has interactive and traditional exhibits, a theater and bookstore, and panoramic views. Nature trails lead along Mendenhall Lake, to Nugget Falls, and into the mountains overlooking Mendenhall Glacier; the trails are marked by posts and paint stripes delineating the historic location of the glacier, providing a sharp reminder of Mendenhall's hasty retreat. An elevated viewing platform allows visitors to look for spawning sockeye and coho salmon—and the bears that eat them—at Steep Creek, a half mile south of the visitor center along the Moraine Ecology Trail.

Several companies lead bus tours to the glacier; ask at the visitor information center. You can also get within a mile and a half of the glacier on the city bus, which is $2 one-way. For a different perspective, you can travel by helicopter to the surface of the glacier, or hire a guide to take you to one of the amazing, electric blue ice caves. Note that because the caves are inherently unstable, the Forest Service doesn't recommend self-guided tours.
