What hidden charges should I watch out for when renting a car in Palma or elsewhere on the island?

Locals often rely on their own vehicles or use the extensive TIB bus service rather than frequently renting cars, so they know to watch for extra costs that catch many visitors by surprise. Rental companies based in Palma or along the Ma-13 and Ma-19 roads often offer appealing base rates online, but these usually exclude essentials like supplementary insurance coverage. It’s important to check in detail whether the quoted price includes third-party or collision damage coverage, as many tourists end up paying more for insurance at the counter if their credit card or personal policy doesn’t cover rental cars.

Fuel policies vary significantly among rental firms on the island. Some require you to prepay for a full tank and return the car full, while others charge a steep refueling fee if you don’t. This can be particularly tricky when you’re planning to explore remote coves such as Cala Mondrago or beaches like Es Trenc, where fuel stops may not be convenient. Other common extras include fees for additional drivers, GPS units — although with smartphones and occasional patchy signal in the Tramuntana, choosing your own navigation tool is often better — and young driver surcharges, especially if you’re under the typical rental age.

If you plan on picking up your vehicle in Palma and returning it elsewhere, such as Manacor or Alcudia, be aware that drop-off location fees might apply. Finally, remember returning the car late, even by a short time, can lead to disproportionate charges. Communicating any delays in advance and reading the rental agreement carefully help avoid last-minute surprises, making your island driving experience much more relaxed and budget-friendly.
