Testimonials
Awesome place, great for children and adults. The Mansion and the trails were great fun! Lovely Gardens and the little Train ride was a treat.
Also a lovely little play area for the children. Will definitely go back. Also, very good Covid measures and I felt safe throughout.
Absolutely a hidden gem in Cornwall. So much fun for my partner, son and myself. We very much enjoyed the mansion and the Indiana trail, the Sherlock trail was great too though definitely too difficult for kids.
More challenging because signal is sparse so there’s no running to Google to figure out the clues. Would definitely come again if only to finish the Sherlock trail! Overall a fantastic day out and great value for money.
An excellent find for a family day out. A cross between a treasure hunt, maze and escape room set in a large outside area. Limited numbers allowed, so social distancing very easy. If you want to cover everything you will need to be here early.
On site restaurant serving limited hot food at lunch time to eat outside (quality burger and chips) as well as drinks and cake. Our kids are 13 and 17 and both found it really good, and there is an easier trail as well for younger children.
This place was amazing. Fun for all ages. The gardens are beautiful with places to walk round and see. The puzzle trails were lots of fun and the Sherlock Holmes trail was really challenging.
The forbidden mansion had a fun quiz to complete and the Moriarty challenges within were also exciting. Would have loved to spend an extra day here!
