The practices are currently being held in Singleton Park opposite Sketty Hall, near where the Dogs Home used to be. The map below shows the location, indicated by the red star.
Drive along the coast road from East to West and take the first turning on the right past the university and go along Sketty Lane. Take the right turning just past the hospital up a slip road. There is a sign which says No Unauthorised Access (or words to that effect). Go to the end of the slip road where there is a bit of parking for cars. Fall out of car, cross a little stream lined with stone blocks and walk up slope into park. You should come out with some trees on your right and you should be able to see Sketty Hall (white building) across the way and hopefully us hitting each other (or sat under the trees waiting for the rain to stop).
