Gorslas sits along the A476 just north west of Cross Hands near Ammanford in Carmarthenshire, South West Wales. Neighbouring villages are Cefneithin and Penygroes. The A48, running from Carmarthen to Llannon, passes close to the village.
Llyn Llech Owain Country Park lies 1km north of Gorslas. The main feature is the large lake, surrounded by coniferous woodland. Other sections of the country park are dry heath and broad leaved woodland.
Footpaths give easy access around the park, and are accessible to wheelchair users. Cyclists will be pleased to know that a forest track circles the Country Park, whilst there is also a rougher mountain bike trail.
