When I saw the small plane I did not feel all to good about flying back to Cancun. It had only twenty four seats and was driven by propeller, which made a lot of noise. Fortunately the weather was good.
The trip included a lot of walking and the guide told us the history of this region, of the Chiapas state and also how it evolved in the context of the entire Mexican country. Very interesting!!!
Puerto Madryn was a boring city, but it was the hub to see the Peninsula Valdes, a nature reserve listed as a World Heritage site by UNESCO. We did not know what to expect but new that we would see Pinguins
