The hiking in Alaska is so good that it’s easy to forget the state has some 47,000 miles of shoreline, including islands, sounds, and bays. “This 10-day crossing of Prince William Sound, from Whittier to Valdez, has everything—calving glaciers, remote beach campsites, and wildlife,” says Anchorage-based photographer Matt Hage. “Plan to take a layover day in Heather Bay to explore Columbia Glacier and spend your last night at Shoup Glacier.” Dense forests grow right up against the shore of the jigsaw-puzzle coastline, and glaciers spill into the water (keep a half mile from the ice). Five types of whales—including humpbacks and orcas—live in the sound, as well as dolphins and sea lions, and on land you might see black and brown bears, moose, and mountain goats.
Skilled kayakers can do it on their own (good navigation and weather chops required); others should go guided (below) on a modified itinerary. Bonus: The Alaska Marine Highway System ferry makes it an easy and affordable DIY expedition. Just be sure to pitch your tent (and store your boat) well above the high-tide line. Rainfall here is measured in feet, not inches, so pack gear for wet conditions, like extra kitchen tarps.
