Whittier, AK

Whittier is Alaska's most unusual small town, where nearly all 400 residents live in a single 14-story building. Located at the head of Prince William Sound, it's accessible only through a 2.5-mile tunnel shared with trains that operates on a timed schedule. The town sits about 60 miles from Anchorage via the scenic Seward Highway and serves as the main gateway for Prince William Sound cruises and fishing charters.
