A small part of the community lies within the Geopark.  Apart from the main town of Llandybie, there are two other large villages at Capel Hendre and Pen-y-groes and a number of smaller settlements at Dre-fach on the Park boundary, at Blaenau, Cwmgwili, Derwydd, Fferws Hill, Morfa, Pentre Gwenlais, Penybanc and Saron; all of the latter some way from the Geopark.

The lie of the land

The community ranges in height from about 25m in the vicinity of Ammanford (SN 623115) to 290m+ in the extreme east (SN 660155). 

The community is drained by the Afon Aman (River Amman) and its tributaries, the Afon Llwchwr (River Loughor), the Afon Marlas and Afon Lash.

Solid rocks

The community is underlain by a suite of rocks which dip moderate to steeply southeastwards.  The oldest in the north of the area are of Silurian age.  These are overlain by a band of Devonian age sandstones and mudstones.

Legacy of the Ice Ages

Much of the area is covered by glacial till whilst glacial sands and gravels occupy the low ground around the village and to the north, across which more recent alluvium has also been laid down by streams and rivers.

Archaeology

Archaeological sites in the vicinity of the park include a scatter of cairns.
