Yes, I can imagine it being cold, the farm park is right up on the hills.
The wildlife park lower down is far more sheltered and also a great day out with DDs. Nice play area and a huge picnic lawn by it. Lovely plants in the walled gardens.
When we went in the spring the banana plants were all wrapped up in sacking and had little sleeping banana signs. My DDs thought it was very funny. I like it best in high summer with all the cannas flowering.
Oh and there are zebras, penguins, monkeys and rhinos to see.
