Step into our world…

There’s something for everyone at Hidden Valley.

Drive down the winding, tree-lined lane to a place where puzzles and adventure await.

Follow the puzzle trails, find your way through the Forbidden Mansion and take in the village of Tremuddlewick.

Watch the miniature railway travel through landscaped gardens, get lost in the Maze, hop on the Porterswick Junction Light Railway and arrive back at the café for a scrumptious snack.

Plan Your Visit

Hidden Valley is a discovery park for all ages, located just outside Launceston in Cornwall off the A30/A395.
There is ample free parking. Entry is by booked tickets only.

Most pathways are laid to gravel and are not easily accessible with a wheelchair or small wheeled mobility scooters. In wet weather, coats and good footwear are highly recommended.
Dogs are welcome on all outside trails and must be kept on short fixed leads (retractable leads are not permitted).
We regret dogs are not allowed in the Forbidden Mansion, on the train or in our play areas.
We welcome group bookings and corporate bookings on a pre-arranged basis.

‘Hidden Valley Puzzle Park is all about puzzles, this is not your usual type of attraction and will involve participation and active detective work to solve some of the clues. If you can’t solve certain clues, then ask us! We want you to achieve as much as possible’
