The 80 acre Show Ground site in Carmarthen is situated directly alongside the main A40 dual carriageway Euro-route linking Ireland to the M4 motorway.

The site is accessed directly from the A40 dual carriageway by slip roads and a flyover making site entry and exit from the both fast, safe and capable of handling a large number of cars without hold-ups.

The very wide quarter mile long entrance road allows three cars to queue side-by-side.  This means that at peak periods, if the pay booths cannot transact as fast as the cars arrive, there is no danger of the queues backing up onto the public highway.

There is parking for more than 1000 cars within just a short walk to the Exhibition hall and the show field.  The size of the car park can be varied depending on the requirements of a specific event.  If the event is only using the exhibition hall then cars can park immediately outside on hard-standing.  The trustees of the society are in the process of making major improvements to the car parking to provide more environmentally sympathetic hard-standing for the cars.

The flat site is ideal for disabled visitors.  There are no steps into any of the buildings and there are metalled roads crossing the site which are ideal for wheelchairs.
