From the Seward Highway take the Portage Road as if going to Whittier. Pass the Begich, Boggs Visitor Center and go through the first tunnel just after passing over the Portage River. Jam Session is located immediately right after passing through the tunnel and to the right of Gangs All Here. Make sure to park your vehicle well out of the way of traffic.
