WE LOVE THIS PLACE! We have been twice in 2 years and would come back again! The mansion is so much fun and the Sherlock Holmes trail was very challenging - 4 of us aged 22 - 60 had to really try hard at the clues! Beautiful trees, flowers and all very well kept and clean! Animals to see, a tiny train for kids (and a couple of 20 year olds!) and a cute little cottage to walk around the outside of. The restaurant was great for us, veggie burgers and chips - yum! Soups, jacket potatoes, quiche, etc and lovely cakes! Seriously, try this place if you can, you won't regret it!

Absolutely brilliant day out for kids and big kids. Found the adult trail actually challenging and the mansion challenge such good fun. Going through the tiny hidden doors really adds to the fun! Restaurant was great, simple well cooked food staff were all friendly and helpful. My only regret about the whole experience was not allowing a whole day for it.

Absolutely superb. Beautiful grounds, clean and tidy. Toilets were first class. Train was lovely and free! This kind of ride is usually a couple of quid each. We all loved the Forbidden Mansion, in fact we went in it twice! Did the more difficult outside trial, which is probably why we stayed for 4 hours! Admission prices were very reasonable too. Highly recommended.

If you want a full day out for young and old alike the hidden valley doesn't disappoint. There is something for everyone and everything is included in the admission price. Superb value for £10 an adult we spent five hours here and still didn't do everything. The restaurant is well priced and the food was very nice. All staff were very friendly and if you take a picnic with you there are literally dozens of picnic spots for you to choose from! Adults make sure you do the Indiana trail as well...it's a good laugh.

Its okay for older kids 8+ I would say. Took my 5 year old and 1 year old. Was not much for us to do but go on the mini train ride and a little play area. I love the escape room but could not do it as the kids was scared. Love the idea of the place and was very clean and well kept.
