Diving in Argentina, South America

Home  |  Locations  |  South America  |  Argentina


Spanning from the subtropics to the sub polar regions of Tierra del Fuego, Argentina sports some of South America’s most diverse and desired dive locations such as Peninsula Valdes, well known amongst divers as a place to enjoy the underwater whale song as it is a rare breeding population of the endangered Southern Right whale and the accelerated breeding of Southern Elephant seals and Southern Sea lions.

Another famous dive site in Argentina is the recently discovered Monte Cervantes Shipwreck at Ushuaia, a main attraction in the well known and highly rated Beagle Chanel.

The waters surrounding Argentina are usually clear with high visibility, but in the summer months the water temperatures rises and plankton growth increases which can lower visibility slightly.

Peninsula Valdes  is found in a peninsula sticking out into the Atlantic Ocean and is attached only by a 5km wide isthmus appearing as if it were a small island attached to the mainland.

Peninsula Valdes boasts an exciting calendar of events, a gathering of the Southern Right whales between June and December but peaking in October, a 500,000 strong colony of Magellan penguins litter the landscape between October and March, calving Elephant seals throughout October, Sea lions calving from December to January and Orcas can be seen 'beaching' in March to catch Sea lion pups.

Between October and March penguins are often hedging on the shore and from June to mid-December it's whale watching season.

Ushuaia in the Argentinean Patagonia, at the southern tip of Argentina is in the famous Beagle Channel, the home of the Monte Cervantes shipwreck.  With beautiful diving comes extreme temperatures, as low as 2C in the winter.

Exploring endless forests of giant kelp surrounding incredible shipwrecks you dive with jellyfish, king crabs, and discover multiple wild and tiny colourful creatures.

Marine Conservation

Peninsula Valdes is a UNESCO World Heritage Site as it is important for almost a third of the breeding population of several endangered special such as the Southern Right Whale.

Peninsula Valdes is known as one of the largest and richest marine ecosystems in the world.

The coast of Argentina almost exclusively nests the Magellanic penguin, numbering more than one million pairs in more than 50 colonies.


The water temperature is very different throughout Argentina spanning between 18C and 23C  in Buenos Aires and 2C to 10C in Ushuaia.

Don't forget that seasons are reversed from those of the Northern Hemisphere and for extreme southern winter diving drysuits are a must as the water can easily reach as low as 8-10C (46-50ºF).

Natural hazards include earthquakes, violent windstorms and heavy flooding.

How to Get there

Buenos Aires International Airport has regular 40 minute shuttle buses, taxis and private cars to the city and a coach connection to Aeroparque Airport.

Aeroparque Airport is the hub when flying out to the rest of the country but if you are not leaving by plane a 15 minute taxi or bus will get you to the city centre. 

Argentina is littered with airports due to the immense size of the country but Argentina offers several more option of transport.

The bus network in Argentina is long but has excellent service; the busses are comfortable and very fast with a choice of classes or sleepers for overnight journeys.

There have been reductions in Argentina’s train service so it is recommended to buy tickets in advance but you can easily reach Buenos Aires as well as Posades and Cordoba, although it is often slower than by bus.


Extreme temperature shifts within a single day are common so pack a variety of clothes.
