Matanuska Glacier is a valley glacier in the US state of Alaska. At 27 miles long by 4 miles wide, it is the largest glacier accessible by car in the United States. Its terminus feeds the Matanuska River. It lies near the Glenn Highway about 100 miles north-east of Anchorage in Glacier View. The glacier flows about 1 foot per day. Due to ablation of the lower glacier, as of 2007, the location of the glacier terminus has changed little over the previous three decades. Nearby State Park: There is an Alaska State Parks facility, the Matanuska Glacier State Recreation Site, a 229 acres park with trails and a small campground. Vehicle & Walking Access: As the largest glacier in Alaska which is accessible by car, travelers have options for up-close viewing or walking on the ice. Matanuska Glacier is accessible by a single road, S Glacier Park Road found at Mile 102 of the Glenn Highway. This gravel road with small bridge crossing comes to an electronic gate operated by Glacier Tours on the Matanuska. Glacier Tours also maintains the remainder of the drive to the glacier, as well as parking, a shelter, paths and picnic tables. Visitors may pay a fee for guided tours with a local guide
