Argentina’s Atlantic coastline runs more than 4,000 km from the Rio de la Plata to Tierra del Fuego, and its character changes dramatically along the way. The Patagonian continental shelf — one of the most productive marine zones in the South Atlantic — draws dense concentrations of albatrosses and petrels within a day trip of Buenos Aires. Further south, the Beagle Channel and Peninsula Valdes combine penguin colonies with genuine offshore seabirding, and Ushuaia serves as the launch point for expedition cruises into some of the most storied seabird waters on Earth: the Falkland Islands, South Georgia, and the Drake Passage.
The directory lists six Argentina pelagic trips across four distinct zones. Here’s what each one offers.
Mar del Plata: The Patagonian Shelf, Close to Buenos Aires
Seriema Nature Tours runs full-day pelagic trips from Mar del Plata harbour, roughly 20 nautical miles into the open South Atlantic. The Buenos Aires shelf break is one of the richest seabird environments in the South Atlantic, and the trip regularly produces Black-browed and Yellow-nosed Albatrosses, along with Southern Royal and Shy Albatrosses on good days. White-chinned Petrel, Southern Giant Petrel, Cape Petrel, Southern Fulmar, Wilson’s Storm-Petrel, and multiple shearwater species round out a typical day.
Mar del Plata’s main advantage is accessibility: it’s a 3–4 hour drive south of Buenos Aires, making it the easiest entry point into Argentine pelagic birding for visitors without the time or budget for a Patagonian expedition. Trips run on request and pair naturally with the operator’s other Argentina birding tours.
Peninsula Valdes: A UNESCO Wildlife Spectacle
From Puerto Madryn, Birding Puerto Madryn leads private, expert-guided tours to the UNESCO World Heritage Peninsula Valdes. The sea cliffs of Caleta Valdes host breeding Magellanic Penguins, Rock Shags, and Snowy Sheathbills, while Dolphin Gulls, Giant Petrels, and occasional albatrosses work the offshore waters.
The standout addition here is Southern Right Whales, which gather close to shore from June through December. Optional whale-watching boat trips from Puerto Piramides put visitors alongside the whales and produce Southern Fulmar, Cape Petrel, and Wilson’s Storm-Petrel on the same outing — a rare combination of world-class cetacean watching and pelagic seabirding in one accessible location.
Ushuaia and the Beagle Channel: Patagonia’s Most Accessible Seabirding
At the southern tip of the continent, Far South Expeditions’ Beagle Channel & Harberton Seabird Tour departs daily from Ushuaia (weather permitting) from October through April. The full-day tour visits historic Estancia Harberton and the Magellanic and Gentoo Penguin colonies of Martillo Island before moving into open channel water, where Black-browed Albatross, Southern Giant Petrel, Imperial Cormorant, Magellanic Diving-Petrel, South American Tern, and Chilean Skua are all routinely recorded.
Because it requires no offshore expedition logistics — just a day out of Ushuaia — this is the most accessible way to combine iconic Patagonian penguin colonies with genuine pelagic species anywhere in the directory.
The Falkland Islands: World-Class Albatross Colonies
The Falkland Islands are listed under Argentina in the directory and hold seabird colonies of global significance. Falklands Nature’s Kidney Island Seabird Evening Trip, led by sixth-generation Falkland Islander Andy Pollard, is a permit-only evening visit to a National Nature Reserve holding up to 100,000 breeding pairs of Sooty Shearwater. As dusk falls, thousands of shearwaters stream back to their burrows in near-darkness — one of the most dramatic seabird spectacles in the Southern Hemisphere — alongside Rockhopper Penguins, the endemic Cobb’s Wren, and Falkland Steamer-Ducks.
For a far more ambitious itinerary, Birdquest’s Falklands, South Georgia & Antarctica Birding Cruise departs Ushuaia and crosses the Drake Passage to all three destinations. Five albatross species are routinely encountered (Black-browed, Grey-headed, Light-mantled, Wandering, and Southern Royal), alongside both giant petrels, Cape Petrel, Blue Petrel, prions, diving-petrels, storm-petrels, and skuas. In the Falklands, the cruise visits the world’s largest Black-browed Albatross colonies alongside five penguin species and Striated Caracaras.
Seriema Nature Tours’ Southern Cone Pelagic Cruise offers a similar scope: a 13-day expedition from Buenos Aires south through Patagonian waters, around Cape Horn, and on to the Falkland Islands, covering more than 35 tubenose species including Wandering Albatross, Blue Petrel, multiple prion species, and six penguin species.
Key Target Species
Black-browed Albatross — The most reliable albatross across all four Argentina pelagic zones; the Falklands hold the world’s largest breeding colonies.
Wandering Albatross — The signature species of the Falklands/South Georgia/Antarctica expedition cruises; among the largest flying birds on Earth.
Southern Royal Albatross — Regular on Mar del Plata trips and Southern Ocean crossings; often seen alongside Black-browed and Yellow-nosed Albatrosses.
Sooty Shearwater — Up to 100,000 breeding pairs at Kidney Island in the Falklands; the evening return to burrows is a signature spectacle.
Southern Giant Petrel — Recorded on every Argentina pelagic zone, from Mar del Plata’s shelf waters to the Beagle Channel and Drake Passage.
Magellanic Diving-Petrel — A Beagle Channel and Tierra del Fuego specialty, seen on the water as the boat moves through channel waters east of Ushuaia.
Cobb’s Wren — Endemic to the Falkland Islands; found alongside the shearwater colony at Kidney Island.
Rockhopper Penguin — Present at Kidney Island in the Falklands, alongside the huge Sooty Shearwater colony.
When to Go
Mar del Plata: Year-round; trips run on request as an extension to broader Argentina birding tours.
Peninsula Valdes: Year-round for seabirds and shore wildlife; whale season runs June through December, peaking September through November.
Beagle Channel (Ushuaia): October through April (austral spring through autumn), with daily departures weather permitting.
Falkland Islands: Kidney Island trips run year-round by arrangement, though shearwater activity is most dramatic during the breeding season. The Falklands/South Georgia/Antarctica and Southern Cone expedition cruises run October through April, tied to Southern Ocean navigation windows and Falklands seabird breeding activity.
Getting There
Buenos Aires is Argentina’s main international gateway and the starting point for Mar del Plata trips (a 3–4 hour drive or short flight south). Puerto Madryn, the base for Peninsula Valdes, is reached by a roughly 90-minute flight from Buenos Aires. Ushuaia, the departure point for Beagle Channel tours and the Southern Ocean expedition cruises, is a 3.5-hour flight from Buenos Aires and is the world’s southernmost city with scheduled air service.
Expedition cruises to the Falklands, South Georgia, and Antarctica book out well in advance — often a year or more ahead for peak-season departures — given limited cabin space and the popularity of the route among both birders and general wildlife travelers. Book early if targeting a specific season.
Seasickness is a real consideration on the Drake Passage crossings and open Mar del Plata shelf waters; sheltered Beagle Channel and Peninsula Valdes trips are far less affected by ocean swell. Read our guide on what to expect on your first pelagic trip for more advice.
