Whittier is nestled at the head of Passage Canal and the closest place to access the waters of Prince William Sound. Located 25 miles south of Alyeska Resort, Whittier is a unique experience. Visitors must travel through the Whittier Tunnel, originally constructed for train travel, but converted in 2000 to handle both trains and auto traffic. The tunnel is opened at regular intervals daily to allow vehicles access to Whittier. For some, the tunnel journey itself is a highlight. The 2.5-mile tunnel is the longest highway tunnel in North America.
Visitors head to Whittier to enjoy day-cruises with boats that tour the glaciers in Prince William Sound. Additionally, sea kayakers enjoy the Sound's beautiful shoreline while anglers on many of the charters leaving from the Whittier harbor search for halibut and salmon. Each June, the tunnel is opened for the Walk to Whittier, a popular local event. After walkers arrive in town, food and entertainment are available.
