The Patagonian plains make way for settlements only where the rare rivers are located. The Chubut river gives its name to an entire province, and provides the water which enabled Welsh settlers to found towns and villages here in the 19th century.

Trelew, one of the larger towns in the area, makes a good base from which to visit the villages which retain aspects of Welsh culture, as well as some of the original buildings. In Trelew itself, there are a few original buildings, but otherwise some of the street names, named after prominent settlers, are among the more visible remnants of Welsh identity.
