The Best Islands in South America to Watch Animals in the Wild
South America isnât just a cultural treasure trove or a landscape of lush jungles and towering Andesâitâs also a haven for some of the worldâs most exotic and unique wildlife. And the best part? Much of this animal magic happens on the continentâs many islands. From colonies of penguins waddling across Patagonian shores to giant tortoises plodding through the volcanic GalĂĄpagos, the islands of South America offer front-row seats to some truly wild experiences.
If youâre a traveler who craves up-close animal encounters in stunning natural settings, then these are the islands that deserve a spot on your bucket list.
1. GalĂĄpagos Islands, Ecuador: The Iconic Wild Paradise
When it comes to wildlife, the GalĂĄpagos Islands are the crown jewelânot just in South America, but globally. This volcanic archipelago, located about 600 miles off Ecuadorâs coast, inspired Darwinâs theory of evolution for a reason.
Wildlife Highlights:
- Giant GalĂĄpagos tortoises
- Blue-footed boobies
- Marine iguanas (the worldâs only sea-swimming lizards!)
- GalĂĄpagos penguins
- Sea lions, frigatebirds, and hammerhead sharks
The animals here have little fear of humans, so prepare for close encounters. Whether youâre snorkeling with playful sea lions or watching a courtship dance between waved albatrosses, every moment feels like a scene from a nature documentary.
Best Time to Visit: June to November (cooler waters, better marine life spotting)
2. Isla Magdalena, Chile: Penguin Party in Patagonia
Looking for tuxedoed charmers waddling in the wild? Head to Isla Magdalena in the Strait of Magellan, Chile. This island is part of Los PingĂźinos Natural Monument and is home to over 120,000 Magellanic penguins.
Wildlife Highlights:
- Magellanic penguins (breeding colonies!)
- Cormorants and gulls
- Sea lions along nearby shores
Youâll walk a designated path through the colony as curious penguins go about their day. Itâs a truly magical experience for wildlife photographers and bird lovers.
Best Time to Visit: October to March (breeding season)
3. Ilha do Cardoso, Brazil: Tropical Biodiversity Hotspot
Tucked away off SĂŁo Pauloâs southern coast, Ilha do Cardoso is part of Brazilâs Atlantic Forest biosphere and a UNESCO-protected paradise for biodiversity. This island mixes rich marine life with dense jungle and river systems.
Wildlife Highlights:
- Dolphins and sea turtles
- Capybaras and howler monkeys
- Over 300 species of birds, including toucans and herons
This is an island where wildlife tourism meets responsible eco-travel. With local guides from the Caiçara community, you can kayak through mangroves or hike jungle trails in search of rare species.
Best Time to Visit: April to October (drier weather and wildlife visibility)
4. Isla de la Plata, Ecuador: The âPoor Manâs GalĂĄpagosâ
Nicknamed the âPoor Manâs GalĂĄpagos,â Isla de la Plata lies just off the coast of Ecuadorâs ManabĂ Province. It offers a GalĂĄpagos-lite experience without the hefty price tag.
Wildlife Highlights:
- Blue-footed, red-footed, and Nazca boobies
- Humpback whales (seasonal)
- Frigatebirds and sea turtles
While you wonât find giant tortoises here, the island has dramatic cliffs and incredible birdwatching opportunities, especially during the breeding season. Plus, humpback whales are often spotted breaching off the coast between June and September.
Best Time to Visit: June to September (for whale watching)
5. Isla Martillo, Argentina: The Penguin Peninsula
Part of the Tierra del Fuego archipelago near Ushuaia (the southernmost city in the world), Isla Martillo is another top penguin-watching destination. Unlike Magdalena, you can see three penguin species here, including the rare Gentoo and King penguins.
Wildlife Highlights:
- Gentoo, Magellanic, and King penguins
- Skua birds and petrels
- Dolphins and whales in nearby Beagle Channel
Only a few tour operators are allowed to land visitors on the island, which helps preserve the ecosystem. If you're lucky, you might even spot a King penguin colonyâsomething extremely rare this far north.
Best Time to Visit: November to March

- Always choose licensed tour operators with strong environmental practices.
- Keep a respectful distance from animalsâno touching or feeding.
