Renting a car at Bilbao Airport (BIO): the practical guide

At Bilbao Airport the rental desks are not in the arrivals hall: you go down one floor and cross into the P1 car park building, following the car hire signs. From the baggage belt to the keys in your hand takes very little time, as long as you have a valid licence, a credit card in the main driver's name and a price already agreed in writing.

What follows is the real sequence: who sits inside the airport grounds and who collects you by shuttle, which surcharges appear when you sign, how to inspect the car when dawn arrives with sirimiri, the fine Basque drizzle, and what to do at the return.

Where the rental desks are at Bilbao Airport

The terminal at Loiu, which everyone calls La Paloma, is compact: one arrivals hall, the baggage belts and little else. The rental offices sit on the lower floor of the P1 car park, linked to the terminal. Follow the car hire signs, go down one floor and walk the corridor: the offices are lined up in a row and the vehicles are on the same level or the one next to it.

• A valid driving licence for the main driver, plus an international permit if it was not issued in the European Union.
• Passport or national identity card, and a credit card in the main driver's name: few desks accept a debit card for the deposit.
• The booking with the price breakdown, printed or on your phone.
• Your flight number on the booking: that is what makes the office wait for you if the plane is late.

Off-airport agencies and the shuttle

Part of the supply at BIO is not in P1 but on business parks in Loiu, Erandio or Derio. Those agencies collect you by shuttle at arrivals and the ride is short, because the airport sits right on the Txorierri corridor. Many independent Basque agencies work this way, with their own fleet and direct contact, and they tend to be more flexible than a large counter. Always ask what time the last shuttle leaves and what time you need to be back on the day you return the car.

The surcharges that show up at the end

Almost no surprise in an airport rental is a mistake by the agency: they are lines in the contract that nobody read in time. These are the usual ones at BIO.

• Airport premises surcharge: if you book with everything settled in advance, it should already be in the price.
• Counter-sold insurance: if you already have cover, say so and ask for it to be noted in the contract; if you do not, decide before you travel, not with a queue behind you.
• Fuel: if it leaves full it has to come back full. Keep the receipt from the petrol station or you will be charged for the refuelling plus a service fee.
• Additional driver: anyone who will drive has to be named in the contract, or the cover may not respond.
• Out-of-hours return: many offices charge it separately and some do not offer it at all.
• Young driver or a recently issued licence: a common surcharge in Spain.

Airport, city or station: which suits you

Picking up at the airport is the most convenient option and almost never the cheapest. If you are spending your first days in Bilbao itself, you may not need a car until the third day: the centre is walkable and the metro and tram reach almost everything.

Inspecting the car in poor light and drizzle

It rains a lot in Loiu, and sirimiri, the fine rain that does not look like rain, is part of the landscape. A wet car hides scratches, and in winter it gets light late: the thirty-second inspection on the car park floor is the single most common cause of a charge that arrives weeks later.

1. 1Switch on your phone torch and walk right around the car, stopping at door sills, wheel arches and both bumpers.
2. 2Film a slow video rather than taking loose photos, with the number plate visible at the start and the end.
3. 3Open the boot, check the spare wheel or the puncture kit and find the high-visibility reflective jacket.
4. 4Compare the fuel level and the odometer with the handover sheet.
5. 5If anything is not noted down, go back to the desk and ask for it to be added before you leave the airport grounds.

Driving in Bizkaia, Gipuzkoa and La Rioja

The Basque Country is pleasant to drive, but it is not flat. Leaving the airport you are on the motorway within minutes and on mountain roads within half an hour, with linked bends, tunnels and fog on the passes. What unsettles visitors is not the speed but the water.

• Speed for cars: 120 km/h on motorways and dual carriageways, 90 km/h on ordinary roads outside built-up areas.
• In urban streets: 50 km/h where there are two or more lanes in each direction, 30 km/h on single-lane streets in each direction and 20 km/h on single-platform streets shared with pedestrians.
• Alcohol limit: 0.5 g/L in blood and 0.25 mg/L in exhaled air. For new drivers with less than two years of licence and for professional drivers, 0.3 g/L in blood and 0.15 mg/L in exhaled air.
• The high-visibility reflective jacket must be reachable from inside the cabin, without getting out of the car to fetch it.
• The emergency warning system is in transition in Spain: check the DGT website, the Spanish traffic authority, for which device is required and ask the agency what the car carries.
• On roundabouts, traffic already on the ring has priority; at unsigned junctions, priority follows whatever signage is in place.

Tolls and the environmental sticker

Many motorways lettered AP are tolled, while other high-capacity roads lettered A are free. Heading for Donostia-San Sebastián on the Cantabrian motorway, or for Vitoria-Gasteiz and La Rioja on the AP-68, expect a toll: you pay by card or with a VIA-T electronic tag. Ask at the desk whether the car has a tag and how it is billed back to you.

Several Spanish cities also restrict entry according to the DGT environmental sticker, which distinguishes the categories 0, ECO, C, B and vehicles with no sticker. The mechanism is almost always the same: cameras reading the plate and a register of authorised vehicles. The rules, the list of cities and the penalties change often, so check the DGT website and your destination town hall before you travel, and confirm with the agency which sticker the car carries. In central Bilbao, on-street parking is also regulated by timed zones, so for a full day an underground car park usually works out better.

The return, and the half hour that decides everything

The return is when the account closes, and it almost always coincides with having a flight to catch. Do it in this order.

1. 1Refuel at a petrol station on the Txorierri corridor, near Loiu, and keep the timed receipt.
2. 2Film the same video as at pick-up, with the car already in the return bay.
3. 3Ask for a signed return sheet; if you use a key drop box, photograph the odometer, the fuel level and the whole vehicle.
4. 4If a deposit was held, ask when it is released and keep the slip.

Work out your timing with early-morning traffic on the Txorierri in mind and, if the agency is off-airport, the wait for the shuttle. An extra half hour of margin is worth more than any discount.

Booking with the price settled before you land

DRIVO is a European marketplace for renting vehicles directly from trusted independent and local rental agencies, and from private owners. Every cost is shown before you pay, including the DRIVO service fee on the rental, which appears as its own line and is refunded with a free cancellation or an agency cancellation. Confirmation is instant, cancellation is free up to 48 hours before pick-up, and you see the security deposit and what is included before you book. At checkout you can add an optional full-protection add-on to lower the excess. Listings and support are available in five languages, with WhatsApp and in-app concierge support. Beyond cars there are vans, motorhomes and campervans where local supply exists.

For a trip along the Basque coast that comes down to something concrete: you land at Loiu knowing the final price and what will be held on your card, and you discover nothing new at the desk.
