The city of Ushuaia, the southernmost city of the world is located on the southern shores of Tierra del Fuego and offers a unique diving experience. The city lies over the shores of the Beagle Canal, one of the three passages that connect the Atlantic with the Pacific Ocean creating a perfect environment thriving with life. The location presents cool water diving and it is suitable for advanced and newly certified divers. It is convenient to have your Dry Suit Certification if you are considering diving these waters, although you can also get it onsite with one of the several dive operators in the city. The Wreck and Deep Diver Certification can also come in handy if you are planing on visiting the interesting wrecks near the city.

The Beagle Canal presents a great biodiversity. The kelp forest which can grow up to 50m/164ft long on average, provides shelter for numerous species of crustaceans, echinoderms and an extensive variety of macro life. The Southern King Crab is a particular inhabitant of the forest and the local communities of Sea Lions love to play around the kelp, so encounters are frequent, especially on Isla Redonda and Estancia Tunel dive sites.

Experienced divers will have the opportunity to enjoy two very popular wrecks in the area. The Monte Cervantes shipwreck, a German transatlantic vessel sunk near the Les Eclaireurs Lighthouse -one of the most meridional lighthouses in the continent- in 1930. This ship is split in two parts, the bow lies at about 90m/295ft and it is beyond recreational diving, but the stern of the wreck sits in over 40m/130ft of depth. The second wreck is the Sarmiento, which lies in shallower water compared to the Monte Cervantes and allows penetration.

Along the boat ride or surface interval divers will also have the opportunity to visit the local Penguin and Sea Elephants communities.
