  • Really good family day out. We went when it was too hot to walk round with a 3 month old baby plus the gravel walkways make it hard for a pushchair. Better for older children x
  • Had great fun at hidden valley so much to do for all the family on a side note the oldish gentleman behind the counter was so friendly made us feel so welcome
  • Fabulous place but make sure you allow to spend the day here
  • This is a brilliant place full of fun for kids and adults.
  • If you love puzzles this is great fun. There are puzzles for all ages. Would be best to visit on a dry day. Love the mansion house in particular. I had a great day out with 4 teenagers.
