What a fantastic day

I went to Oakfield park with my 4 and 5 year old boys and in their words it was the best day of our holiday ever! From the start we were met with extremely kind and enthusiastic staff members who couldn’t be more helper. My son’s played in the playground and explored all Oakfield had to offer for six hours. It was so clean and well looked after. A hidden gem we will definitely be returning to.

Great day at Oakfield Park yesterday

Had a wonderful guided tour of the upper gardens (delighted to see 4 acres of wild flowers coming up and wild garlic everywhere) then strolled around the lower gardens later on. Scrap was still with us the last time we were here and his photo by the Faerie Tree is still one of my favourites. Oakfield is more beautiful than I remember and Morholt the Land Giant is amazing! Coffee at Buffers was great and cheap. Something for everyone.

Santa Express

By FAR the best Santa experience we have visited. Every part is so well planned and feels so professional. From the train to the grotto to the outdoor entertainment and puppet show. My sons loved every bit of it. We ate at the restaurant and the food was so easy to order and quick. All round a 5* experience.

Fantastic jewel of a location.

Beautiful gardens and superbly maintained. It is beautifully presented with wonderful facilities and staff. The railway is a gem and so much fun. The restaurant has good value food and great coffee. So much to see in the grounds. Do not miss a visit to Oakfield.
