Punta Tombo is a long haul from Puerto Madryn, but in penguin season it is worth the effort. Thousands of Magellanic penguins nest here, and the visitor paths let you watch them move between burrows and the sea without turning the colony into a petting zoo.
The season generally runs from September to March, with chicks later in spring and summer. Combine it with Trelew only if you start early; otherwise it deserves most of a day.
