Hidden Valley Discovery Park, Puzzle-focused amusement park near Launceston, Cornwall, England
Hidden Valley Discovery Park is a puzzle-centered amusement park near Launceston in Cornwall with multiple themed trails and a building called the Forbidden Mansion featuring hidden passageways. The grounds include a Victorian-style reception building, gravel pathways, and a café that serves visitors throughout the day.
The park began as a treasure hunt attraction in 1994 and developed over time into a larger entertainment destination with expanded features. Growth brought additional rides and experiences that built upon the original puzzle-solving concept.
The trails here draw inspiration from detective fiction and adventure stories, with names referencing famous characters and their worlds. Visitors walk through spaces designed to feel like scenes from mystery narratives, creating an environment where storytelling shapes how people move through the park.
Wear sturdy shoes when visiting, especially after rain, because the gravel paths can become slippery and uncomfortable. A café on site offers food and drinks so you can take breaks without leaving the park.
Throughout the Forbidden Mansion, visitors solve puzzles to collect crystals as they progress, mimicking the structure of a game show competition. This hands-on element turns the visit into a personal adventure with a tangible reward.
