If you’re heading home from Europe in your motorhome via Calais, one topic always seems to come up in conversation between van lifers and motorhomers: stowaways. It’s one of those things people hear about, worry about, and –thankfully – rarely experience. But the truth is, it’s a real risk and something that we should all be taking very seriously.
Recently on the Motorhome Matt Podcast, we dived into what motorhomers need to know when returning to the UK through Calais, focusing on keeping your vehicle secure and avoiding the nightmare scenario of encountering an unexpected passenger. Here’s what you need to know before entering the ferry or Eurotunnel terminal.
Why it’s such a concern at Calais
The port of Calais is one of the busiest crossing points between mainland Europe and the UK. It’s also a hotspot for people trying to enter the UK illegally, often hiding in or under vehicles.

Although commercial lorries are the primary targets, motorhomes are easier alternatives – they’re quieter, less tightly packed, and often left unattended for long periods in car parks or queues. Stowaways aren’t just a ‘big van’ problem anymore. Even small campervans can become targets if they appear vulnerable.
What could happen if you’re found with a stowaway in your motorhome
- The consequences of unwittingly transporting someone are serious. You could face:
- Hefty fines (up to £2000 per stowaway).
- Delays and questioning by Border Force.
- Being turned around at the border. Increased scrutiny on future trips. Even if you didn’t know someone had climbed in or under your ’van, the responsibility still falls on you
as the driver. That’s why prevention is key.
Top tips for avoiding stowaways
1 Stay with your vehicle where possible Don’t leave your motorhome unattended in Calais for long periods, especially in service stations or laybys near the port. If you must take a break or grab food, park in well-lit, busy areas with CCTV or security. Service stations away from Calais – say, 30–50 miles back – tend to be quieter and safer for an overnight stop.
2 Evidence a thorough check before travel Before you head into the terminal or join the queue to board the ferry:
- Check underneath the chassis, and inside storage lockers, bike racks and roof boxes.

- Open and inspect garage spaces, and anywhere someone could conceivably hide.
- If you have rear ladders or a spare wheel carrier, check those too – people have been known to cling on in unimaginable ways.
- Look for any signs of forced entry or disturbed items. Make it a routine part of your pre-travel checks, like putting on a seatbelt. Pre-travel, create and print a checklist that you can tick off and keep as evidence of your role in taking responsibility. Use your phone to photograph or video yourself checking your motorhome. It is helpful evidence if you are challenged.
3 Use security devices Motion-sensor lights, security cameras, or even simple padlocks on lockers can act as deterrents. Having the best motorhome wheel clamp or a steering lock might not stop a stowaway, but they often signal you’re a security-conscious owner, rather than a soft target.
4 Talk to others Don’t be shy – chat with other motorhomers at stopovers near Calais. Share concerns and observations. There’s strength in numbers, and a friendly community keeps more eyes on what’s happening. Many people form informal ‘convoys’ on the final leg back to the UK, offering additional reassurance.
What Border Force will check
You may be subject to a random vehicle check or sniffer dog inspection at the port or terminal. Some ’vans are scanned using heat sensors or even heartbeat monitors; others are visually checked. Be co-operative and open – these checks are in place to help protect you, as much as anyone else. Being seen to take sensible precautions can go a long way if there’s any question about whether you’ve done your bit.
What to do if you discover someone
If you find someone trying to hide in or around your vehicle, we are advised not to approach them but instead:
1 Lock your vehicle doors and secure yourself and your passengers.
2 Call the police or alert port security immediately.
3 Report the incident calmly, with no confrontation. It’s frightening, but the authorities are trained to deal with it. The important thing is to stay safe and let them handle it.
Final thoughts
Travelling back via Calais is something many of us do without issue, year after year. But as with all aspects of motorhoming, some preparation goes a long way. By being aware, staying alert, and taking sensible precautions, you can protect yourself and others from an experience nobody wants. So before you set off for home, add ‘check for stowaways’ to your pre-crossing checklist. Safe travels, and welcome home!
