About South Eryri (Snowdonia)
Bordered by the beautiful Dwyryd and Dyfi estuaries, the mountains of south Snowdonia include some of Wales' most fascinating National Trust places It is here that the roots of the Trust took hold, with the acquisition in 1895 of Dinas Oleu. Separated by the dramatic Mawddach estuary, the mountain ranges of Cader Idris and the Rhinogydd dominate the scenery and the area's coastline includes some of the most ecologically important sand dunes in the British Isles. The area is a stronghold of the Welsh language and culture and is extremely rich in prehistoric and medieval archaeology.
