Are there any hidden costs I should watch out for when renting a car in Mallorca?

Car rental on the island often includes additional fees that aren’t immediately apparent. For instance, insurance is a major factor; though your credit card or personal policy might cover basic liability, rental companies usually try to upsell collision damage waiver or theft protection, which can notably raise the total cost. Before signing, it's essential to review the terms carefully to avoid surprises, especially regarding roadside assistance which you might be charged for by default if you don’t explicitly decline it.

Fuel policies also demand attention. Many agencies expect the car returned with a full tank, but should you come back underfilled, the refueling charges might be disproportionately high, particularly if renting from airport locations like Palma de Mallorca Airport. Moreover, rentals booked at the airport tend to carry extra fees such as facility or concession charges that can push your bill upward beyond the initial quote.

Keep an eye on mileage restrictions as well—some vehicles come with capped limits, and exceeding them invites additional fees that can add up quickly if you plan to explore the Serra de Tramuntana or take longer drives along the Ma-13 or Ma-19. Asking pointed questions at the rental desk and thoroughly checking the paperwork will help ensure your time driving between Valldemossa, Sóller, or Cala Mondragó goes smoothly without unexpected costs.
