Welcome to Hidden Valley Discovery Park

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

OPEN DAILY 10am until 5pm


Hidden Valley opened in 1994, with a garden shed in the field, with a Scavenger trail and a small display of chocolate bars for sale, a small woodland play area soon saw a tea room and array of tin sheds, garden railway, cottage, telephone box and walk in mine tunnel. A few years later saw the introduction of the Vault and a miniature railway taking guests around the park. The theme of treasure hunts and detective trails has continued throughout. 2013 saw the opening of the new visitor centre and Forbidden Mansion with further enhancements; gardens, maze and railway tunnel in the latter years. 2019 our 25th year sees the opening of Tibbohton.

Visitor Centre

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. New for 2019 will be Tibbohton, more details to be released shortly.

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.
