Whittier  is a popular departure point for day trips to the glaciers of Prince William Sound  mid-May–late September. Phillips Tours and Cruises (907/276-8023 or 800/544-0529, www.26glaciers.com ) operates the 4.5-hour 26-Glacier Cruise for $139 ($79 children). The trip aboard its 340-passenger Klondike Express—a high-speed three-deck catamaran—covers a lot of ground but still allows plenty of time to linger at the faces of several glaciers. A hot lunch is included, there’s a bar on board, and the lounges provide plenty of room inside should the weather be less than perfect. The schedule is timed so that you can ride the train from Anchorage  and back (an additional $80) or take a bus (an additional $50).
