The turn off for Portage Valley Road and the Begich, Boggs Visitor Center is located approximately 50 miles south of Anchorage or 77 miles north of Seward on the New Seward Highway #1.
Turn onto Portage Valley Road and go approximately 5 miles to the end. Follow the road to the right and there will be a turn-off to the Portage Glacier Lodge on the left. Keep following the road as it loops around.
The first road off to the right after you pass the lodge is the road to the Ptarmigan boat dock. Lake front parking is just up ahead and if you continue towards the visitor center, there is available parking with special areas for busses and larger vehicles.
