If you follow the Panamericana from Puerto Montt down to the south it will end suddenly and you need to take a ferry boat to the island of Chiloé. It is a wonderful place where you have the possibility to see penguins in their natural habitat. A very good place for this seems to be Puñihuil beach – you can reach it if you turn west after the ferry usage and pass the town of Ancud; and then simply continue through empty landscapes.
