Deep in the woodland is a puzzling place…

Where families and friends will find mysteries to chase

Follow the puzzle trails, find your way through the Forbidden Mansion, escape the Study, shrink and grow in the Ames room and take in the village of Tremuddlewick.

Discover Tanglwood Hollow play area, get lost in the Maze, hop aboard a Train, relax in our gardens and enjoy a snack from the Watering Hole Cafe

All terms and conditions apply at booking.

Hidden Valley is a Puzzle Park for all ages, located just outside Launceston in Cornwall off the A30/A395.
There is ample free parking. Entry is by booked tickets or on the gate. Booked tickets are cheaper.

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, Study, or on the train.
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’
