Ushuaia town has a large port and several nice touristy streets on the front length of a steep hill. After the first three streets though, there is not much left to be seen. So tourists concentrate on the large souvenir shops like the one offering carved figures of “indio rose” pink-colored stone. They have all animals, as penguins and dolphins, dancers and other figurines carved in stone.
Other shops offer sports goods, clothes (I bought a fleece jacket) and belts, bombillas and metal filter straws for mate tea (if you like the bitter taste), postcards and books, cafés and restaurants and a small “museum”.
Of course one can walk around the port, which has its own selection of fine shops, and watch all the boats coming in.
