Traveled alone with two kids (6&4) arrived at lunch time and parked in the car park nearest Oakwell hall. It is free to park as is the other car park near the play area.
First we sat outside on the grass at the front of the hall and had our picnic, we took a blanket but there are plenty of seating areas to choose from. It was quite busy but certainly not overwhelming.
After lunch we went in the hall which cost £2.50 for adults and a £1 for kids so cheap on entry. The staff were friendly and we were given a guide book (you hand it back at the end). The guide was informative as were the info boards in each room. The kids especially liked the ghost story and did seem a little spooked. The hall is lovely and well worth paying the small entry fee, it certainly has a lot of character with it's sloping walls, floors and ceilings. It was a nice look around and not too busy with just one other family in there at the same time as us.
The gardens are attractive and well kept, the kids loved running through the mini maze and chasing the butterflies.
A look in the gift shop next, it is very reasonably priced and great for pocket money items that the kids were keen to pay for by themselves.
We used the toilets opposite the gift shop which were clean.
We did not eat in the cafe but it did look quaint with seating outside.
It is a pleasant third of mile walk from the hall through fields along a zig zag path to the play area. It is a well thought out play park and the kids loved it. There is a little shop that sells refreshments and also another toilet block.
Overall a great semi rural day out that doesn't break the bank. Would definitely visit again.
