The last town in this area that really retains a Welsh feel to it is Gaiman. It´s a small place set back in the Chebut valley and was settled in the late 1800´s.
There are about 5 "traditional Welsh tea houses" in the town and I stayed overnight in one with guestrooms - Plas y Coed. One of the owners- Anna - spoke Welsh.
I also went to the museum here which is small and run out of the old railway station. It´s managed by a lady called Mrs Roberts who is in her late 70´s/early 80´s and has lived in the area all her life. She has a strong Welsh accent and has family back in North Wales.
I found it all very interesting and the place itself was a relaxing place to chill for 24 hours.
Off to the most Southern town in the world now - Ushuaia - which is at the tip of Argentina. It´s about 36 hours way on the bus so I´m getting a flight down there.
