Southern right whale in Argentina: when and where to see them in their natural habitat

Southern right whale: an iconic species of the South Atlantic

Each year, the southern right whale (Eubalaena australis) arrives along the coast of Península Valdés, in the province of Chubut, Argentina, to mate, give birth, and care for its calves. This whale migration begins in late May and extends through mid-December, turning the region into one of the most renowned destinations for whale watching in Argentina.

The southern right whale is one of the most emblematic species of the Southern Hemisphere. It can reach up to 16 meters in length and weigh around 50 tons. Its large, dark body, with no dorsal fin, is easily recognized by the callosities on its head, which are unique to each individual and allow for identification. Females, larger than males, give birth to a single calf approximately every three years.

This species was nearly driven to extinction due to commercial whaling during the 19th and 20th centuries. Since then, its population has recovered significantly in Argentine waters, especially in the Nuevo and San José gulfs. Scientific research indicates that these whales have used these areas as breeding grounds for over 1,000 years, taking advantage of the calm, shallow waters ideal for raising their young.

The best time for whale watching in Patagonia

The official whale season in Península Valdés runs from June to December, although the first whales begin to arrive in late May. During July and August, it is common to see mothers swimming with their calves near the coast, making these months ideal for whale watching from land.

As spring approaches, the activity intensifies. In September and October, there's more interaction between individuals: breaching, vocalizations, and playful behavior among the calves. This period, with more favorable weather conditions, is considered the best for boat excursions. For many travelers, it’s the best time to see whales in Patagonia.

Puerto Madryn: the ideal starting point

Located on the Nuevo Gulf, Puerto Madryn is the quintessential base city for those traveling to see whales. Its hotel infrastructure, tourist services, and air connectivity make it the main logistics hub for exploring Península Valdés and other marine observation areas.

One of the most special nearby spots is Playa El Doradillo, just 15 km from the city center. During winter months, it’s possible to see whales from the shore, without needing to board a boat. They approach just meters from the beach, offering a moving and accessible experience, even for families with children or people with limited mobility.

Puerto Pirámides: boat excursions in their natural habitat

The town of Puerto Pirámides, located within the protected area of Península Valdés, is the only authorized location in Argentina for nautical whale watching excursions. From June to December, boats with specialized guides depart daily to observe whales in their natural environment.

Tours last between 1.5 and 2 hours, and are conducted in semi-rigid boats or catamarans. During the trip, it's common to see whales breaching, fluking, and exhaling just meters from the vessel. Beyond the visual spectacle, operators also provide educational information about the species’ biology, behavior, and conservation status.

Marine wildlife watching in southern Argentina

In addition to whale watching, the Península Valdés and Puerto Madryn region offers numerous activities that deepen your connection with nature and local culture. A highly popular option is snorkeling with sea lions at Punta Loma — a safe, regulated experience that allows visitors to swim with these curious creatures in their natural habitat.

Another fascinating option is birdwatching in the wetlands near the city or in the El Doradillo Protected Area. The region is home to more than 180 bird species, including flamingos, oystercatchers, and cormorants. For photography lovers, coastal landscapes at sunrise or sunset provide ideal backdrops with unique light and active wildlife.

On land, photo safaris through Península Valdés offer the chance to spot guanacos, foxes, maras, and rheas, as well as visit key sites like Punta Norte or Caleta Valdés, where visitors can see colonies of elephant seals and sea lions in their most natural state.

For a cultural approach, a visit to the Ecocentro Puerto Madryn — a center for scientific outreach, art, and the environment — offers deep insights into the marine life of the South Atlantic. Its clifftop building overlooks the sea and even allows for whale sightings from its terraces during the season.

A recommended travel plan

A four-day visit allows for a full experience. On the first day, explore Puerto Madryn, visit the Oceanographic Museum, and enjoy the waterfront. On the second day, head to Playa El Doradillo early in the morning, when the sea is calmest, to watch whales from the beach.

On the third day, travel to Puerto Pirámides and take a boat tour. Weather permitting, this can be combined with a visit to the cliffs of Caleta Valdés or the sea lion colonies at Punta Norte or Punta Loma. On the fourth day, consider another boat trip or a coastal trail walk as a memorable way to say farewell to the Patagonian ecosystem.

Exclusive experiences for demanding travelers

For those seeking something different, the region offers premium experiences that combine nature, comfort, and personalization. It's possible to book private whale watching tours on exclusive boats — ideal for photographers, couples, or families wanting an intimate moment with marine wildlife.

Some operators offer scientific-focused trips, accompanied by biologists who share their research onboard. There are also glamping options on Patagonian ranches in Península Valdés, allowing you to sleep surrounded by nature in luxury tents with all amenities. These experiences, tailored for high-end travelers, allow for a deep and personal connection with the Patagonian environment.

Practical tips for whale watching

If you’re planning a trip, it’s best to book accommodations and tours in advance, especially between September and November, the peak tourist season. Temperatures are usually low, even in spring, so bring warm, wind- and waterproof clothing. Sunglasses and sunscreen are also essential, as UV radiation can be strong even on cloudy days.

Another key tip is to check weather conditions before boarding a boat, as tours depend on sea state. All excursions must be carried out with authorized operators who follow environmental protocols and ensure visitor safety. This guarantees a respectful and secure experience for both animals and humans.

How to get to Puerto Madryn from abroad

For international travelers, the main gateway to the region is Ezeiza International Airport in Buenos Aires. From there, take a domestic flight to either El Tehuelche Airport (Puerto Madryn) or Trelew Airport (60 km away). Both cities are connected via transfer services, buses, or car rentals.

Long-distance bus companies also operate regular routes from Buenos Aires to Puerto Madryn — a journey of approximately 20 hours.

Seeing a whale in its natural habitat is a moment that stays with you forever. Hearing its breath, watching a calf swim beside its mother, or witnessing a full breach on the horizon are indescribable experiences. For lovers of ecotourism and wildlife observation, watching the southern right whale in Argentina is much more than a tour — it's a journey into the wild and into emotion.

Península Valdés, a UNESCO World Heritage Site, is home to one of the planet’s largest mammals and offers a protected natural setting where visitors can truly connect with nature and wildlife in its purest form.
