The lungs of the city! Edinburgh is blessed with so much green space, but my favourite is the meadows. It's a collection of humanity with people on it every second of the day. Cycling, dog walking, playing Quidditch (really!), playing crickte, tennis, slackwiring etc and in May and June it's full of people barbecuing. It's just along from Bruntsfield Links that has a free short hole golf course on too.
