6 Best Sights in The Kenai Peninsula and Southcentral Alaska, Alaska

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 just a 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.

In addition to fishing, clam digging is popular at Clam Gulch, 24 miles south of Soldotna on the Sterling Highway. This is a favorite of local children, who love any excuse to dig in the muddy, sloppy goo. Ask locals on the beach how to find the giant razor clams (recognized by their dimples in the sand). Ask also for advice on how to clean the clams—cleaning is pretty labor-intensive, and it's easy to get into a clam-digging frenzy when the conditions are favorable, only to regret your efforts when cleaning time arrives. The clam digging is best when tides are minus 4 or 5 feet. A sportfishing license, available at grocery stores, sporting-goods shops, and drugstores, is required for clam diggers 16 years old and older.

A visit to Columbia Glacier, which flows from the surrounding Chugach Mountains, should definitely be on your Valdez agenda. Its deep aquamarine face is 5 miles across, and it calves icebergs with resounding cannonades. This glacier is one of the largest and most readily accessible of Alaska's coastal glaciers. The state ferry travels past its face, and scheduled tours of the glaciers and the rest of the sound are available by boat and aircraft from Valdez, Cordova, and Whittier.

Matanuska Glacier is the largest car-accessible glacier in the country, with a four-mile wide terminus that can be seen from the road. Right off the Glenn Highway (Mile 102), the entrance is maintained through Guided Glacier Tours. The only way to visit is on a guided tour—a number of companies offer glacier these.

The glacier is a frequently visited tourist destinations. A 6-mile side road off the Seward Highway leads to Begich-Boggs Visitor Center on the shore of Portage Lake, named after two U.S. congressmen who disappeared on a small-plane journey out of Anchorage in 1972. The center is staffed by Forest Service personnel, who can help plan your trip and explain the natural history of the area. A film on glaciers is shown hourly, and icebergs sometimes drift down to the center from Portage Glacier. Due to global climate change, Portage, like most of the glaciers in Alaska, has receded greatly in recent years, and it's no longer visible from the road. However, you can view it on a scenic cruise or via a hike.

A mass of ice that caps the Kenai Mountains, the Harding Icefield covers more than 1,100 square miles, and oozes more than 40 glaciers from its edges and down the mountainsides; Exit Glacier is the most accessible part of the ice field. Just outside Seward, if you hike a mile up the paved trail that starts at the parking lot, you'll find yourself at the terminal moraine of Exit Glacier. Look for the marked turnoff at Mile 3.7 as you enter town, or you can take the hourly shuttle from downtown ($15 round-trip). There's a small walk-in campground here, a ranger station, and access to the glacier. The hike to the ice field from the parking lot is a 9-mile round-trip that gains 3,000 feet in elevation, so it's not for the timid or out of shape. But if you're feeling up to the task, the hike and views are breathtaking. Local wildlife includes mountain goats and bears both black and brown, so keep a sharp eye out for them. Due to recent ice fall at the toe of the glacier, the entire toe is currently off-limits.
