Hi Flogster,
Welcome to the forum.
I used to go to college in Lem. and if memory serves me correct there a large park with a children's play area with soft bark matting round the back of the college. I'm not sure if that's what you looking for, and it's been about 5 years since I was there last.
I don't know if there's anywhere in town that provides play areas though, there's a lot of parks in the town and I'm sure at least some of them have play areas.
Sorry I can't be more help then that.
