If you hit the red Alyeska Pipeline road block you have gone too far. This campground was a little confusing to drive around and very very wet in Mid September so bring your rain jacket. The drive out to this campground can be a little bumpy and times so take it slowly. The drive around this campground is a bit rough in spots as well. Totally worth it and with no one else on the entire campground it was pretty epic. The campground is situated right above the Arctic Circle sign so if there are a bunch of people waiting for pictures you can always sang a great shot early in the morning before other people are there.
