Quick facts
Getting ashore
When to visit Puerto Madryn
The cruise season runs through the austral spring and summer, roughly October to March. Southern right whales are present in the gulfs from about mid-June to mid-December, peaking in September and October, so late-season and early-season calls have very different wildlife on offer.
Getting back to the ship on time
Península Valdés is more than 100 km each way and Punta Tombo about 180 km, roughly 2.5 hours’ drive on partly gravel roads — these are genuine all-day commitments with real back-aboard risk. Book independent tours only with operators who guarantee return by all-aboard, or take the ship’s excursion.
All-aboard is ship's time — check it in the daily programme, and set your watch to it.

A little history
Puerto Madryn was founded on 28 July 1865 by 153 Welsh immigrants who arrived aboard the sailing ship Mimosa and came ashore at Punta Cuevas, beginning the Welsh colony in Patagonia known as Y Wladfa.
The Welsh language and traditions survive inland in the Chubut valley towns of Gaiman and Trelew, where Welsh tea houses still serve torta negra galesa about 80 km from Puerto Madryn.
Península Valdés was inscribed as a UNESCO World Heritage Site in 1999 for its globally important populations of southern right whales, southern elephant seals and sea lions.
The city is home to Aluar, Argentina's only primary aluminium smelter, which opened in the 1970s and transformed a tiny coastal settlement into a working industrial port.
