The Hidden Valley Discovery Park reviews
We had a fantastic time when we came in October half term. We had pre booked so we knew it wouldn't be overly busy, we arrived and checked in at the reception and had a brief explanation of the... more »
Really great afternoon even in the constant rain. The children (7 and 4) enjoyed the indiana trail, and train ride. Would definitely visit again. more »
You need to get here early as it will take all day to solve all the clues. Moriatis house is great fun. You are inside the mansion and have to solve 6 clues to escape from the rooms. Your time is recorded and points for time taken. Outside there are two trails, one for the younger children and an adult one. About 25 clues around the grounds and some are not easy. You take all the letters and have to unscramble the letters to get the answer. Great day out to get your brains working. Lovely cafe and plenty of parking. Staff very helpful and friendly. Check out your scores on an electronic score board. Good luck.
A quirky place in a great setting. Puzzles good for the kids and some harder ones for the adults too. The mansion House was very interesting..food seemed to run out though around dinnertime??!!!Had to buy cake instead. Little train was quite fun.A good day out.
