Visiting the Perito Moreno glacier was a highlight of the trip for me. It's the kind of tourist site that is heavily visited for completely understandable reasons. We spent a couple hours in the park following the pathways and then jumped the fence to bat a few rocks into the lake.
The town of Calafate was loaded with tourists, high season had begun. The place where we were staying even had a sign boldly explaining that its prices had risen for this reason. We still had a great dinner of asado, roasted lamb.
That night we camped near the outflow from Lake Argentina, Rio Santa Cruz. The drive into the town of Rio Gallegos, the self-proclaimed windiest town in the world was uneventful.
