I have just added this to the map of places to fly your drone at Drone Scene:

Astbury Mere Country Park was the site of a former sand quarry in the 1980’s. At the time I believe there were some interesting conversations as to what should be done with the land.

Today the park hosts Congleton’s 5k park run, Astbury Watersports Centre and a nice little coffee shop.

There is parking onsite which is chargeable or just outside you can park for free
