We are 2 weeks into our trip, my favourite experience so far was when we went to Punta Tombo. It's the 2nd largest colony of Magellanic Penguins in the world. The Penguins are really cool because they are so cute when they waddle.
For the penguins to find food they swim up to 600km. They eat the food then swim back home to find their burrow where their family is. To feed their family the Penguin barfs the food up and shares. It's really hard for the Penguins to find their burrows because there are hundreds of thousand, and if you walk in front of the penguin they get confused because they like to take the same route.
Something that I find hard is to make friends because I don't know Spanish.
