Portage Glacier Recreation Area is accessed via 5-mile paved road at mile 79 of the Seward Highway. The road ends at a large parking lot next to Portage Lake with excellent views of the floating icebergs. The road continues another 6 miles to Whittier, which requires travelers to pass through the Anton Anderson Memorial Tunnel. At 2.5 miles long, it is the 2nd longest tunnel in North America.
The first stop at Portage Glacier should be the Begich-Boggs Visitor Center, which contains a number of exhibits as well as a highly recommended film, “Retreat and Renewal: Stories from Alaska’s Chugach National Forest.” The Glacier has receded over three miles in the past century and is no longer visible from the Visitor Center, which was built in 1986. It is open daily in summer 9 to 6. 907-783-2326.
