The Inn at Whittier is located about an hour south of Anchorage in the small town of Whittier, Alaska. Follow the Seward Highway south out of Anchorage along the Turnagain Arm. Turn left at Portage (about mile 40), then travel several miles to Bear Lake, the start of the Whittier tunnel.
The Whittier tunnel is generally open from 7:00am-10:30pm during the winter (Oct 1 to April 30) and from 5:30am-11:00pm during the summer (May 1 to Sept 30). The tunnel is only one lane wide and more than two miles long, so traffic is allowed through on an hourly schedule. Inbound traffic is released on the half-hour.
