Among Giants: Best Whale Watching in South America

September 20, 2025 | by: Kuoda Authors

It’s one thing to see a whale. It’s another to feel one. The ocean stills. A hush falls. Then, a tail breaches the surface with grace and power, and you’re left in awe.

Welcome to the best whale watching in South America, where giants roam the seas and every encounter reminds us of nature’s majesty. From the warm Pacific currents of Peru to the icy edges of Patagonia, this continent offers world-class marine encounters. With Kuoda, your experience is deeply personal, expertly guided, and always unforgettable.

Peru: Gentle Giants of the North

In northern Peru, the convergence of the cold Humboldt Current with warm equatorial waters creates one of the richest marine ecosystems on the planet. Between July and October, this region becomes a nursery for humpback whales migrating from Antarctica to give birth and raise their young in the calm shallows.

One of the most incredible destinations for whale watching is Los Órganos, where you can witness humpbacks breaching in synchrony and hear their eerie, melodic songs through underwater hydrophones. On a Kuoda-arranged excursion, you might even find yourself observing a mother and calf in a quiet moment of rest or play, guided by a marine biologist who explains every movement with insight and care.

If you want the best whale watching in South America with intimacy and warmth, northern Peru delivers it wrapped in sun, salt, and wonder.

Chile: The Vast and the Rare

Chile offers a contrasting marine world, raw, remote, and wildly beautiful. From December to May, the coastline becomes a feeding ground for a range of cetaceans. Most impressive is the elusive blue whale, which makes occasional appearances in Chilean Patagonia and the southern fjords.

In Francisco Coloane Marine Park, humpbacks can be seen launching into the air with glaciers as a backdrop. In Punta de Choros, visitors might glimpse sperm whales and bottlenose dolphins, while the Guaitecas Archipelago offers encounters in tranquil, unspoiled waters.

This is one of the best whale watching destinations in South America for those craving wild terrain, biodiversity, and a taste of scientific exploration. With Kuoda, your journey includes sustainable lodging, private boat charters, and access to conservation experts who share stories from the front lines of ocean protection.

Argentina: Close Encounters in Patagonia

Few experiences compare to standing on the shores of Argentina’s Valdés Peninsula and watching a southern right whale glide past, sometimes just meters away. From June through mid-December, these majestic creatures arrive in the protected waters near Puerto Madryn to breed and nurse their young.

This is classic whale watching, done the Kuoda way: with private guides, boutique accommodations, and immersive interpretation of one of nature’s greatest migrations. The drama intensifies in October and November when orcas use their intelligence and agility to beach themselves in pursuit of seals, a rare and raw display of predation seen in only a few places worldwide.

When it comes to accessible, powerful wildlife encounters, Argentina offers some of the best whale watching in South America. And with Kuoda, you experience it in a way that’s meaningful, respectful, and unforgettable.
