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.

When does this hunt work best?
A mermaid birthday party or a summer afternoon in the garden — and if you’ve got a paddling pool, dip the clue cards in water first so they feel properly fished out of the sea. It works indoors too (“mermen don’t walk, they swim!” keeps the living room calm), and it’s longer and more story-focused, so it suits children who love an immersive adventure. Older children can help younger ones read the clues.
