Laguna San Rafael (170 square km) is part of San Rafael National Park (1,742,000 Has), with its floating icebergs and the big glacier Valentine in gradual decline. A spectacle of nature that you can live near shiping in small boats, to receive the baptism of cascading water and drink a whiskey with ice from the glacier itself. Careful with the waves that are collapsing ice. The pure blue of the ice is impressive. Money well spent, because the trip takes three days. I explain in other post.
