Pets on ferries from Piraeus
Short answer: Yes, pets travel on most Piraeus ferries, but you must declare the animal when you book, and you need the right paperwork: a health book or EU pet passport, a microchip, and a current rabies vaccination. Small pets usually travel in a carrier; dogs may need a leash and muzzle and are often restricted to designated deck areas. Pet-friendly cabins exist on some conventional ships and are worth booking early. High-speed catamarans accept pets only under stricter conditions, so check the vessel before you choose the sailing.
A common failure is not a refusal on the gangway, it is a booking made without the pet, or paperwork that does not match the animal. Fix that before you travel and the crossing is usually straightforward.
Pet rules are set by the operator and the ship, and Greek/EU documentation rules apply. Confirm with your operator and, for cross-border travel, a vet before booking.
The booking step you cannot skip
- Declare the pet at the time of booking. Online systems usually ask for species, size, microchip number and health-book/passport number. If the field is missing, contact the operator and get the pet added in writing.
- Book the actual animal. A pet registered as "small dog" when you arrive with a large dog can be refused, and a registration cannot be transferred to a different animal.
- Check whether a pet ticket is required. Some operators issue a free or fixed-fee pet ticket; others include the pet in the passenger booking. Limits on pets per booking and per cabin also vary. Do not assume "pets go free" means "no booking needed".
- Keep the confirmation with your ticket. Gate staff may ask for the pet registration before boarding.
- If you add a pet after paying, expect a reissue or ticket change rather than a free edit.
Documents to carry
For travel within Greece:
- Health book / EU pet passport showing the animal's details.
- Microchip number matching the passport.
- Current rabies vaccination, within the validity period.
- Owner ID and booking confirmation.
- Any medication or veterinary letter if the animal is on treatment.
For travel from another EU country or a third country, additional rules apply (EU pet passport, tapeworm treatment for some destinations, health certificates, import rules). Check with a vet and the relevant authority before booking the ferry; the operator is not responsible for border compliance.
Keep digital and paper copies. Port phone signal and desk queues are not the place to discover that the microchip number on the booking is wrong.
On board: cabins, carriers and deck areas
| Option | Typical rule | Practical advice |
|---|---|---|
| Pet-friendly cabin | Some conventional ships; book early | Best for long crossings and anxious animals |
| Ordinary cabin | Usually not allowed | Do not assume you can take a pet into any cabin |
| Carrier on passenger deck | Small pets in a secure carrier | Check the operator's size limits |
| Designated deck area | Dogs leashed/muzzled; weather-dependent | Shade and water are essential |
| Vehicle deck | Pets should not stay in the car | The deck is closed and heat rises |
| High-speed catamaran | Stricter limits; often deck or carrier only | Check the vessel and the operator's size limits |
Rules that catch people out:
- Access to restaurants and some lounges is restricted. One traveller may need to stay with the animal while the other eats.
- Deck areas can close in bad weather. Have a carrier as a fallback.
- Crew instructions override your plan. If they ask you to move, move.
- Do not leave a pet unattended in a cabin, carrier or public area for long periods.
Heat, stress and seasickness
- Piraeus in summer is hot. Tarmac and quays can burn paws; walk in shade and carry water.
- Book a morning or evening sailing if you can. Midday crossings are hardest on animals.
- Shade and airflow matter more than a fancy carrier. A towel over the carrier helps, but never block ventilation.
- Feed lightly before travel and avoid a heavy meal immediately before boarding.
- Seasickness medication for pets only on veterinary advice, and test the dose before travel day.
- Brachycephalic breeds (pugs, bulldogs, Persian cats) are heat- and stress-sensitive; a conventional ferry with open deck access is usually kinder than a high-speed.
- Toileting: walk the dog before boarding, carry bags, and plan a toilet stop on arrival. Ferries do not have pet toilets.
Choosing the right sailing
- Conventional ferry is usually better: more deck space, more stable motion, more likely to have a pet cabin or designated area.
- Short crossing beats a long one. A pet that tolerates 1–2 hours may struggle with 9.
- Overnight can work well in a pet cabin, but not on deck in winter or in a carrier for nine hours.
- High-speed is faster but more restrictive; narrow aisles and limited outdoor space make it harder for nervous animals.
- Avoid the last sailing of the day if a refusal would strand you; an earlier sailing leaves room to rebook.
At the port
- Arrive early: not for the pet's paperwork, but for the toilet stop, the walk to the gate and the chance to sort out a problem before boarding closes.
- Use the pet boarding route if one is indicated. Do not push a carrier through the vehicle ramp queue.
- Keep the pet controlled on the gangway. A retractable lead is not enough near moving vehicles; use a short lead or carrier.
- Have documents ready in a plastic sleeve, not buried in a suitcase.
- If boarding is refused, contact the booking line or port agency immediately with the registration details. Do not argue at the ramp; rebook the next suitable sailing.
FAQ
Do I have to register my pet when booking a Greek ferry?
Yes. Most operators require the animal to be declared at booking, with species, size, microchip and health-book details. Boarding can be refused if the pet is not on the booking or the details do not match.
Can my dog sleep in my cabin?
Only in pet-designated cabins, and only if you booked one. Ordinary cabins do not accept animals. Pet cabins are limited, so book early.
Are pets allowed on high-speed ferries?
Sometimes, with restrictions. High-speed catamarans often limit pets to carriers or specific deck areas. Check the vessel and operator before booking.
What if the ferry is cancelled or the pet is refused?
You can usually rebook or request a refund under the operator's conditions, but pet cabins and spaces may not be available on the next sailing. Have a backup sailing and, for long trips, a pet-friendly hotel option.
