Puerto Chacabuco is a Chilean town in Ais�n commune. Administratively it belongs to Ays�n Province in Ays�n del General Carlos Ib��ez del Campo Region and is located at the head of Ais�n Fjord. It is the main port of the region, a port of call for ships sailing to the Laguna San Rafael National Park and the terminus of a Navimag ferry service from Puerto Montt.
Before the great burnings of the Patagonian forests and the eruption of Mount Hudson volcano in 1991 Puerto Ais�n was the main port in the Ais�n Fjord, but the ashes and earth erosion decreased the navegability of Ais�n River and the port had to be moved further to the coast where Puerto Chacabuco now stands
