Ushuaia

Ushuaia is a port city at the southern tip of Argentina, often used as a gateway to Patagonia’s southern diving adventures. While the town itself sits on the Beagle Channel, it offers access to cold-water Atlantic ecosystems via nearby dive sites and expedition operators. Expect strong currents, kelp forests, and marine life typical of subantarctic waters, with easier access for acclimated divers and researchers. The city’s infrastructure supports year-round travel, with a focus on expedition logistics, chilly water diving, and access to remote subantarctic sites from Tierra del Fuego.
