What hidden fees should I watch out for when renting a car on the island?

Driving through the Serra de Tramuntana or exploring secluded coves like Cala Llombards means a reliable rental car is essential, but it's wise to be aware of possible extra costs that can inflate your bill. Insurance add-ons are perhaps the most common surprise; rental agencies often include basic coverage but will push costly extras such as collision damage waivers or theft protection. Before you accept these, check whether your own car insurance or credit card offers equivalent coverage to avoid paying twice.

Fuel policies used by companies operating around Palma or along the Ma-13 highway can also cause confusion. Most follow a full-to-full rule, requiring the tank to be returned full. Returning it even slightly underfilled can result in expensive refueling fees, often much higher than local gas stations near Manacor or Alcudia. Some renters choose prepaid fuel options for convenience, but these rarely offer good value, so filling up locally before returning is generally smarter.

Additional services like GPS units—handy for navigating to spots like Formentor—or roadside assistance might appear practical but carry daily surcharges that quickly add up. Furthermore, be conscious of possible fines for returning your vehicle late, especially if your trip includes busy festival periods such as Nit de Foc in Palma. Reviewing your rental terms carefully and confirming all fees upfront will keep surprises out of your holiday budget and let you enjoy the island’s winding roads with peace of mind.
