The city of Puerto Madryn is in the north east of Chubut Province in the Patagonia region of Argentina. The city is on the shores of Gulfo Nuevo, a large deep water bay of the Atlantic Ocean.
The city is a popular summer destination for its beach. The beaches are beautiful though the water can be very cold and the wind impressive.
The current population is estimated between 60,000 to 70,000. The city has been growing rapidly in the last few years due mainly to the expanding tourism industry, fishing and Aluar-the aluminum refinery.
Puerto Madryn is the gateway to nearby Peninsula Valdes.
The area was first populated by the indigenous Tehuelche people.
The first Europeans to settle in the area were Welsh arriving in 1865. They named the city for Baron Madryn of Wales.
Plane: Puerto Madryns Airport is located 10 minutes from downtown. Currently there are three flights per week from Buenos Aires on Andes Airlines. Aerolineas Argentinas flies to Trelew, which is an hour from Puerto Madryn. Shuttle buses operate from the airport in Trelew to Puerto Madryn and cost arg$20.
Puerto Madryn has a city bus system. Taxis are numerous. Rental cars are available.
From Puerto Madryn daytrips run to Punta Tombo. This is a penguin colony where you can walk among thousands of penguins between the months of October and March.
Often combined with a visit to Punta Tombo is a boat trip to spot the small black-and-white Commerson's dolphins. During the months of June through March.
Many tour agents run trips to visit Peninsula Valdes. Here one can see penguins and a great number of sea lions and elephant seals, depending on the season. In January, all three can be seen (though no whales), including sea lions giving birth. Puerto Piramides is the only major town of Peninsula Valdes. Many tours will have a stopover here -- there is a nice beach and some bars and restaurants. There are boat tours and kitesurfers, among other things.
Punta Loma, seventeen kilometers southwest of Puerto Madryn is a sea lion reserve. It can be reached by bike. Beware- the road is not paved and your bike may sink into the sand. On the up side, there are deserted rocky beaches (very lovely) if you take any of the side paths off of this sandy road.
The EcoCentro is a great and modern marine interpretation centre offering interactive information on marine life in the region. Located overlooking the gulf to the south of the city on Julio Verne 784. 
Whale Watching, the Southern Right Whale uses the waters of Gulfo Nuevo for breeding and giving birth. They are easily seen from the shore and pier. Whale watching boats depart from Puerto Pyramides located on Peninsula Valdes.
