Forest Highway 35 (FFH-35) is a Federal Forest Highway located entirely within Chugach National Forest. The highway is approximately long, and is mostly designated along the Portage Glacier Highway. The road serves the Portage Glacier branch of the park. FFH-35 begins at an intersection with the Seward Highway (AK-1) in Portage. The route follows the Portage Glacier Highway for approximately , passing several park campgrounds and scenic turnouts. FFH 35 turns off the Portage Glacier Highway onto Portage Lake Loop Road, passing west of the Begich, Boggs Visitor Center Complex. The designation then shifts from Portage Lake Loop Road to Byron Glacier Road, which proceeds southward past low-lying marshland along Portage Lake. It continues past a small turnout area and travels over a small creek before proceeding eastward to its eastern terminus, a building and parking lot that make up part of the visitor center.
