Welcome to Hidden Valley Discovery Park

Cornwall’s ‘hidden gem’ attraction that’s great entertainment for everyone

Our new visitor centre welcomes visitors before their day begins, with its extraordinary design, the curiosity starts to ignite…

Discovery and exploration is the game, whether you chose our intriguing outside trails, the fast pace fun of Moriarty’s Missions or simply to explore the park and discover an unfolding kaleidoscope of uniquely landscaped grounds.


The mysterious Forbidden Mansion hides weird and wonderful rooms, secret passageways and the challenging Moriarty’s Missions. Take a train ride around the park on the Porterswick Junction Light Railway, with its bridges, cuttings and a snaking tunnel.

Our Restaurant serves delicious meals, cream teas and mouth-watering cakes , and a great range of gifts and curiosities can be found in our gift shop.

Park is now closed: It will be opening again for October half term 21st-28th inclusive
