Recommend me a good play area

Where abouts is the bigger play area ?

As you drive in the normal entrance, just before you turn left to go over the bridge into the car park, it's straight on.

Let me put a pin on the map. Hopefully this works for you:

I wrongly read the OP as not a soft play area, but he does indeed say that doesn't cost money.

Graves park is brilliant, There's the farm and a big playground, all free.

Also +1 for Poolsbrook & Clifton

There is nothing to touch Clifton park for children when the weather is good.

The parks and gardens department do a superb job for the people of Rotherham.

Can have a good adventure up around Rivelin
