Oscar turned to me mid-hunt and said, "Mum, I actually AM a merman now, aren't I?" And yes, son. Yes, you are.
Sometimes the best treasure hunts are the ones where the children genuinely forget they're at home and believe — absolutely believe — they're somewhere else entirely. This one drops them into Neriya, a hidden underwater realm where the guardian fish need their help. The children become mermaids and mermen, follow an enchanted map through coral reefs and sea caves, solve eight connected riddles, and uncover an ancient ocean secret. The storytelling is woven right through it, so they're not just solving puzzles — they're saving a kingdom.

🎯
Best for: ages 4–9, indoors or in the garden, 4–10 children. This one's longer and more story-focused, so it works brilliantly for kids who love immersive experiences. Budget 60–120 minutes. It also works beautifully if you've got mixed ages because the older children can help the younger ones read the clues.
Hannah’s honest tip: The underwater theme is brilliant for keeping everyone in character — "mermen don't walk, they swim!" means less running around the living room like absolute maniacs. Also, if you've got a paddling pool, even a small one, you can dip the clue cards in water beforehand so they feel genuinely discovered from the sea. Oscar's crew thought that was the best bit.
