Ushuaia is the capital city of the Tierra del Fuego province in Patagonia, commonly referred as the southernmost city in the world, being also an important naval base. It is located in a wide open bay, on the south coast of Isla Grande de Terra del Fuego and bordered in the north by the Martial mountain range.
Ushuaia has subpolar oceanic climate with warm summers and cool winders. The city is surrounded by Magellanic subpolar forest rich in flora and fauna with several recreation activities. However, Patagonia in not only about mountains and forests. The cold waters at “the end of the world” hide mysteries, waiting to be discovered and diving can be a real challenge.

Rich in marine life and biodiversity, this reef cave is a fantastic adventure for scuba divers. The average depth of this location is at 15 m/49 ft and the maximum at 23 m/75 ft with medium current. The water visibility is good but it gets better during winter.
