How to Use what3words at a UK Festival: Find Your Tent, Get Help Fast
what3words is the most useful UK festival app of the last decade and most festivalgoers still don’t know about it. Three random words pinpoint a 3-metre square anywhere on Earth. It works offline. UK emergency services use it. Glastonbury, Latitude, Boomtown and dozens of other festivals’ medical teams use it. And it solves the single most common festival problem: finding your tent at 3am in a sea of identical pitches. This is the practical guide to actually using what3words at a UK festival — how to set it up, what to share, what to do when there’s no signal, and the safety scenarios where it matters most.

Quick answer: how do I use what3words at a festival?
Download what3words before you leave home (App Store / Play Store, free, ~50MB). Mark your tent location the moment you’ve pitched — three random words appear (e.g. ‘beats.crisp.lemon’). Save those words in your phone notes, write them on your wristband, and share them with your group. Works offline — the app generates and reads codes without signal. For emergencies — give the three words to the medics, stewards or 999 operator. UK emergency services accept them as standard.
What what3words Actually Is
what3words divided the entire planet into 3-metre squares and gave each one a unique three-word combination. Each square has its own three words: e.g. ‘silver.brand.tubes’, ‘beats.crisp.lemon’. The system works without numbers, addresses, GPS coordinates or postcodes — and it works offline once the app is installed. Three words are easier to remember, easier to share by voice, and harder to mistype than a 10-digit GPS coordinate.
Why It Matters at a UK Festival
- Tents look identical at night. A 60,000-tent campsite has no addresses. Coming back from the main stage at 1am, you’re searching for a tent shape in the dark.
- Signal is unreliable. Standard maps need data. What3words generates the words from your phone’s offline GPS.
- Emergency response is faster. Stewards and medics at most major UK festivals are trained to recognise three-word codes. So are 999 operators.
- Sharing meeting points is simpler. ‘Meet me at the orange flag’ is ambiguous. ‘Meet me at silver.brand.tubes’ isn’t.
- You don’t need an address. Festival sites don’t have street addresses; what3words doesn’t need them.
Step-by-Step: How to Set It Up Before the Festival
- Download the what3words app from the App Store (iOS) or Play Store (Android). It’s free.
- Open it once at home and grant location permissions. You don’t need to register an account.
- Test it works offline. Turn airplane mode on; open the app; it should still display your three-word location.
- Pre-save your phone’s emergency contacts with their phone numbers — separate from any what3words usage.
- Charge your phone before leaving. what3words runs on basic GPS but your phone still needs power.
On Site: The Six what3words Moves That Matter
1. Mark your tent immediately after pitching
Open what3words, capture the three-word code for your tent’s exact spot, and screenshot it. Save the screenshot to your phone’s lock-screen photo or favourite a note containing the three words.
2. Write it on your wristband
Use a permanent marker on the inside of your festival wristband or write it on the inside of your wrist itself. If your phone dies, the three words are still on you. If you lose your phone, the words help others help you.
3. Share with everyone in your group
WhatsApp the three words to your festival group chat. If someone gets separated, they have a way back without depending on you. Share once at the start of the weekend and pin the message.
4. Use it for meeting points
Lost track of friends in a crowd? Open the app at where you are now, share the three words. Whoever’s looking for you opens the app, types the three words, gets walking directions to your spot.
5. Give to medics or stewards
If you need first aid, fall ill, or need someone to come to you — give the three words to the steward or medic. UK festival medical teams use what3words extensively. They’ll find you faster than a vague ‘I’m in the green camping field somewhere’.
6. Use it in 999 calls
UK police, fire and ambulance services accept what3words. If you have to call 999 from a festival site, the operator will ask for your location — three words is faster and more accurate than ‘I’m at Reading Festival, somewhere in the orange field’. All UK 999 control rooms can convert the words into precise coordinates.
🚨 What to do if you can’t find your tent at 3am
Open what3words. Type your saved tent’s three words into the search box. The app gives you a compass and walking directions. If your phone is dead, the words on your wristband let a steward, friend or anyone with a working phone help you back. If neither works, head to the nearest welfare tent — they’ll help.
what3words Failure Modes (And How to Cover Them)
It’s not magic. Things that can go wrong:
| Failure | Why It Happens | How to Cover |
|---|---|---|
| GPS struggles in dense crowds | Phone GPS can drift in stadium-density areas (~10m error) | Mark your tent in clear field conditions, not from inside a crowd |
| Phone battery dies | Days 3 and 4 of camping festivals are a battery graveyard | Write the three words on your wristband, not just your phone |
| You forget which words | Easy after a long day | Screenshot it; pin a note; share with your group |
| Wrong words shared | Typos when sharing manually | Share via the app’s ‘Share’ button, which copies exactly |
| Multiple people in your group share their tent | Confusion about which words refer to what | Label each shared location: ‘TENT — silver.brand.tubes’ |
Battery and Signal: The Double Failure
what3words is robust against signal loss — it works offline. It’s not robust against your phone dying. By Day 3 of a UK festival, dead phones are everywhere. The power bank rules are: 20,000 mAh minimum, 20W output minimum, charged before you leave. Inline article: the free Festival Survival Guide PDF covers the full charging strategy.
How UK Festivals Actually Use what3words
Most major UK festivals’ medical, security and welfare teams use what3words to coordinate response. When you give a steward the three words, they relay them on radio; the response team types the words into their app and walks straight to you. Glastonbury medics, Latitude welfare, Boomtown security, Reading and Leeds festival liaison teams all use it. It’s quietly become standard infrastructure.
Beyond Tents: Other Festival Uses
- Find the car park aisle you parked in. Same problem as tents, different surface.
- Mark the food trucks you liked. Festival sites are big; finding ‘the curry van I liked’ on Day 3 isn’t always easy.
- Note the toilets nearest the stage you’ll be at. Saves the lap of the field.
- Tag the meeting point for friends arriving Friday. Pre-arranged ‘meet at the flag’ becomes ‘meet at signal.beats.crisp’.
- Hire car or campervan recovery. If your car breaks down on the way home in a rural field, recovery services accept what3words.
Frequently Asked Questions
Is what3words free?
Yes, the consumer app is free to download and use, on both iOS and Android. There’s no subscription, no in-app purchase requirement, and no advertising in the standard version.
Does what3words work offline at a UK festival?
Yes. Once the app is installed, what3words generates and reads three-word codes from your phone’s GPS without needing internet or mobile signal. The mapping does require offline maps to be downloaded if you want to see the surrounding area visually, but the core code-reading and code-generation works offline.
Will UK 999 operators accept what3words?
Yes. UK police, fire, ambulance and coastguard services have integrated what3words into their control room systems. When you call 999 from a festival site, give the three words and the operator can convert them to precise coordinates.
Can I use what3words to find friends at a festival?
Yes — share your three-word location through any messaging app. The recipient opens what3words, types the words, and gets walking directions to your spot. Works inside the festival without signal as long as both phones are working.
How accurate is what3words?
Each three-word combination represents a 3m × 3m square — accurate to roughly 3 metres. That’s accurate enough for finding a specific tent or meeting point but not down to specific corner of a tent.
Will my phone GPS work in a tent or under a flag?
Yes — phone GPS generally works fine inside fabric tents and outdoors. It struggles inside large metal structures or deep in concrete buildings, but neither is a typical festival environment.
Can I share a what3words location to someone without the app?
Yes. Share the three words by text, WhatsApp, voice or written down. The recipient can type the words into what3words.com on any browser to see the location on a map.
Does what3words drain my phone battery?
Like any GPS-using app, it uses some power when actively in use. But you don’t need to leave it open in the background. Open it, mark the location, close the app. No more battery drain than any other navigation app.
Is what3words available in different languages?
Yes — what3words supports over 60 languages. Each language has its own three-word system; the same physical location has different words in English vs French vs Mandarin.
What if I’m at a festival outside the UK — does what3words still work?
Yes. what3words covers the entire planet, including festival sites in mainland Europe, the US, and worldwide. Same app, same three-word system, just translated where you select a different language.
