Castro: Capital of Chiloe
Castro is the biggest city in the island of Chiloe. In fact, I would say that it's almost the only city, since the other towns around the island are actually towns.
What makes Castro so fantastic is the fact that being a city, it preserves that Chiloe-town-like sense. Also, it's a good city to stop by and make it a hub city to explore the other towns nearby.
Definately one of Chile's must-see towns.
