Family spy treasure hunts for city breaks. Real secrets. Real cities. One file, works offline. Let them lead. Watch them shine.
Real families on real missions in real cities. Share your photos with #HiddenCityHunt or email us and we'll feature you here.
No app to download. No account to create. No instructions to wade through. If your kids can use a phone, they can run this mission.
Pick your city for €12.50 (one device) — or grab 3 devices for the same city for €25 (3 for the price of 2 — perfect for the whole family on one mission). Your mission file arrives by email within minutes.
Open the file once before you leave — at home or at the hotel. This loads the spy map. After that, it works completely offline. No signal needed on the day. No roaming charges.
Your child enters their agent codename and receives their classified dossier. They navigate, investigate, and crack ten coded passwords to unlock the city's secrets. You walk alongside and enjoy the ride.
No need to find every secret — your agents tap "Call HQ" to finish whenever they're ready. Every solve triggers confetti, and they earn a badge for their haul: Spy, Super Spy, or the full Mega Spy badge with a personalised certificate for completing the whole city.
Little legs get tired, attention wanders, ice cream calls — so your agents decide how far to go. Find as many hidden locations as you like, then tap "Call HQ" to finish whenever you're ready. The more you uncover, the higher the rank — and every agent comes home a winner.
Crack any 3 locations and your agent earns their Spy badge — officially on the case. A real win, even on a short stroll.
Reach 6 locations and they level up to a Super Spy badge — and they'll have unlocked their well-earned mid-mission treat along the way.
Solve the whole operation (10 locations in most cities) for the top Mega Spy badge plus a personalised certificate with their agent name on it.
Every badge and certificate saves straight to the phone — a keepsake from the day they cracked the city. 📸
When your kids get stuck on a code, miss a clue, or wander past the entrance to a hidden chapel, their agents step in. Each one has a specialty — codes, history, navigation, languages, patterns — and each one drops a personalised field clue at the right moment.
Not another museum queue. Not another audio guide nobody listened to. This is the day your kids talk about for years — because they did it themselves.
Your kids hold the dossier, read the briefings, navigate to each location, and figure out the answer themselves. You follow at their pace — which turns out to be surprisingly fast when they're motivated. The look on their face when they crack a tough one is the moment you came for.
Every location is a real hidden story — history, science, art, architecture. The kind of fact that sticks because they discovered it themselves, standing in front of it, having worked to get there. No worksheet. No quiz. Just genuine discovery.
Cracking a coded password and watching confetti explode across the screen is a real moment of triumph. Getting all ten is something they'll actually boast about. The mission certificate at the end is theirs — earned, not handed to them.
A few things the kids don't need to worry about — but you might.
Most of the locations on each mission are free (we love a hidden alley). But a few of the showstoppers — a museum, a tower, a cathedral with a fee — will need you to pay your way in. We'd cover it if we could, but we'd have to charge €450 per city and it'd be weird.
→ Each operation tells you which stops have entry fees and roughly how much, so there are no surprises.
Halfway through every mission, Agent Tracker insists the team takes a break for a snack. Ice cream, a pastry, a local sweet — something. This is technically a "treat reward" but it's also fundamentally a bribe so the kids keep going for the second half. Either way: bring some cash.
Most missions are walkable. Some involve a tram, a metro hop, a ferry, or — once or twice — a cable car. We're not the boss of you, but it's worth having a travel pass or some change handy just in case.
Especially in Athens, Rome, Singapore, and basically any city that has the word "warm" on its Wikipedia page. Hydrated agents are happy agents.
The file needs no signal once it's open, so you're covered on data — and there's no need to crack every location. Your agents tap "Call HQ" to finish whenever they're ready, so if someone needs a wobble halfway through, let them. The rewards scale with how much they uncover, so every agent earns something to be proud of.
→ Find 3 locations for a Spy badge, 6 for a Super Spy badge, or the whole city for the top Mega Spy badge plus a personalised certificate with their agent name on it.

Each hunt is built around real hidden places that most tourists — and most locals — walk straight past. Ten locations. Ten coded passwords. One unforgettable day.
A church hidden in an attic for 150 years. The world's only microbe zoo. The narrowest house in Europe. A sailors' bar that accepted live monkeys as payment.
A Cycladic island village built overnight on the Acropolis slope. The world's oldest weather station. The world's first theatre. Steam power invented 1,700 years early.
Roman columns hidden in a hiking club. A 6th-century synagogue below street level. A square where Civil War shrapnel is still in the church walls.
A Cold War spy hill built from WWII rubble. Berlin's fairy-tale fountain. An empty library beneath the cobblestones. A ghost theme park whose Ferris wheel still turns.
Africa's oldest building. A mountain older than the dinosaurs. The penguins that nobody expected. The garden that saved a kingdom of plants.
A throne made from narwhal tusks the craftsmen thought were unicorn horns. A time traveller's grave. An elevator that never stops. 22,000 unique beer bottles.
700-year-old mummies in a church crypt. Saint Valentine's actual remains in a golden casket. A tree eating a park bench. The last arch of Dublin's lost medieval wall.
A church spire the Devil tried to twist. The world's longest bar. An art gallery hidden in a road tunnel. The valley where Neanderthal man was found.
Michelangelo's secret hiding room. Wine holes in palace walls. His graffiti carved in seconds on a palazzo. The door competition that accidentally started the Renaissance.
Where the internet was invented. A building with zero right angles. A 12-metre broken chair outside the UN. Two rivers flowing side by side that refuse to mix.
A glacier-fed turquoise lake. A 19th-century wooden walkway through a one-metre-wide gorge. Switzerland's oldest funicular. A pier that turned a tiny village into a worldwide pilgrimage.
Two Victorian houses that are pure painted facade. A wall honouring forgotten heroes. A secret underground postal railway. England's smallest square behind an unmarked arch.
A skull-lined bone church, a bull buried in gold, a defiant fist in the financial district, a cathedral with 135 spires hiding centuries of secrets.
Manhattan's first paved street, from 1658. An abandoned subway station with crystal chandeliers. A pneumatic-tube tunnel from 1870. The smallest piece of private property in the city.
Eiffel's secret apartment where Edison visited. The alchemist's house whose tomb was found empty. 135 bronze discs tracing France's rival to Greenwich. A bookshop where writers sleep free.
The bookshop built from painted plaster not wood. 20,000 tiles telling 8 centuries of history. A Moorish palace inside a stock exchange. A fishing village frozen in 1960.
The most beautiful library nobody visits. A street 50cm wide with its own traffic lights. An elevator that never stops. A garden with free-roaming peacocks nobody finds.
A keyhole that frames three countries at once. A mouth that bites liars. A crypt of 4,000 monks' bones. The spot where Caesar was stabbed — now a cat sanctuary.
A temple built without a single nail. The bunker where Britain surrendered the empire. The last village on the island. The world's first nationwide broadband nation.
A Roman emperor's palace that became a living city for 1,700 years. 507 taxidermied frogs in human scenes. The only sport in the world played only in one city.
A sandstone bench carved by convicts in 1810. The world's first surf lifesaving club. The last thylacine, dead since 1936. The flying foxes of the Botanic Garden.
A devil's bridge, a cat's funeral carved in stone, a Roman racetrack buried under the streets, and a tower locals called Pontius Pilate's home for 800 years.
The shrine that survived the firebombs of 1945. The temple where lucky cats were first invented. The world's first cat-café district. The eternally loyal dog Hachikō.
An Art Deco temple to the sea. The world's narrowest commercial building. A hollow tree taller than your house. The cannon that fires every night at nine.
"My kids refused to go to museums. They did this for six hours and didn't want to stop. I was the one suggesting we take a break. The bone crypt terrified and absolutely thrilled them."
"My daughter was the navigator, my son handled the passwords. They were a team. I just walked with them and watched. It was honestly one of the best days we've had on any holiday."
"My son stood at the Jonction for ten minutes just watching the two rivers refuse to mix. He figured out why himself. Still talks about it six months later. That's the kind of thing that stays."
