Unfortunately there is no Post Code for Walters Arena but the following post code will get you to the traffic lights in Glynneath, SA11 5TU. From there follow the map below. The site entrance is set back from the road and not easy to see.
The SA10 post codes used in the past will not get you to the site but will take you down a long no through road where you will meet a very irate farmer.
When leaving the site watch out for the mobile speed camera when coming down the hill into Glynneath.
