About 1,400 km from Buenos Aires and in a peninsula that juts out to the Atlantic Ocean, Valdes is a a wild animals’ paradise and a UNESCO World Heritage Site. Peninsula Valdes is connected to the continent by a strip of land about 5 km wide. It looks like a small island hanging from the continent. Highlights at this unique site include:

Other inhabitants include sea lions, elephant seals, armadillos, guanacos, maras and gray foxes.

Ushuaia is a small city at the southern tip of Argentina and is often referred to as the 'City at the End of the World'. It is in the famous Beagle Channel. The diving here is beautiful, but can be very cold! Swim through forests of giant kelp, visit amazing shipwrecks, dive with jellyfish, king crabs, and discover many varieties of tiny colorful creatures.
Since the winds are usually less frequent in winter, the water is calmer and clearer, but much colder! In summer, when water temperatures rise, plankton growth increase which lowers visibility. Water temperature in winter is about 2-4C (36-40F). In summer, it can easily reach 8-10C (46-50ºF). Drysuits are a must!
Patagonia is cool in the summer and cold in the winter. Extreme temperature shifts within a single day are even more common here; pack a variety of clothes and dress in layers.
