With some great detective trails for all the family, fun prizes, a fantastic mansion to explore, a wonderful train ride around the park, a mouthwatering menu in our tea room and gifts galore in our gift shop, Hidden Valley is a great place to visit for everyone.


Forbidden Mansion

Secret doors, passageways that get smaller and smaller, a fireplace to crawl through, a dining room that is upside down and so much more......

And somewhere, perhaps even under the stairs, is something that is very strangely familiar!

Your adventure starts at the imposing front door as you enter this mysterious Mansion. Step inside and discover lots of surprises, twists and turns as you make your way through this amazing indoor puzzle. Don't be fooled by the what seems likea small exterior! It truly has a tardis effect

Porterswick Junction Light Railway

Take a ride on our scenic miniature railway on over a mile of track around the park.

Pulled by our lovable diesel locomotive 'Albert No 1', climb aboard for a fun journey travelling under bridges, through deep cuttings, and past forest trees - there's even the thrill of a snaking tunnel. Board the train at the new Mansion House station and travel around the whole park as many times as you like... you get unlimited rides all day!


Hidden Valley Nature

At Hidden Valley we have acres of wonderful grounds to explore. Hundreds of trees and shrubs, provide shelter and food for all sorts of wildlife such as buzzards, song birds, rabbits and deer who all make their home in our native woodland and pine forest

Have fun getting lost in the Beech Hedge Maze. See if you can make your way to the centre and climb to the top of the wooden fort..
