Looking for park with swings

I know this is a really specific ask but I am looking for a playground in Edinburgh with a swingset that is suitable for an older child.

Our 13 year old is autistic and one of her calming activities is swinging on a swing. We are traveling for the holidays away from our home in the US and are hoping to find a park with a swingset sturdy enough for an older child.

We are staying near Princess St Gardens but can Uber a reasonable distance.
