Trelew is the largest city in the Chubut region of Patagonia with a population of 100,000. There is a wide variety of bird life here; one the the chief attractions is the flamingo.
A heavy Welsh influx starting in the mid 1800s gave the city its name. The Welsh were integral in the construction of the Argentinean railroad and it was originally a railroad town. It's Trelew where 90% of wool in Argentina comes from.
Punta Tombo, 110 km. south of Trelew, is the site of the largest colony of Megellanic penguins in the world. Numbering 1,000,000, you can see them there between April and September.
