What hidden fees should I watch out for when renting a car to explore Mallorca?

Booking a car lets you explore beyond Palma and into the winding Serra de Tramuntana or the secluded coves of Cala Mondrago, but it pays to know where extra costs may appear. Insurance is often a hidden charge, though many credit cards or personal policies already cover collision or theft protection. Confirm what your coverage includes before accepting extra insurance offered by agencies, which can quickly increase your bill.

Fuel policies are another common surprise. Rental companies typically require the tank to be returned full or charge premium prices to top it up, especially if you pick up your car at Son Sant Joan airport. Pre-paying for fuel might be handy if you plan to use the car extensively on routes like the Ma-13 to Pollenca or the Ma-19 down to Cala Llombards, but do the math to decide if it’s cost-effective. Also, watch for mileage limits—surpassing the allowed kilometers can mean a hefty per-mile surcharge.

Airport rentals sometimes carry a surcharge, so asking upfront about any additional fees at Palma's airport can prevent unwelcome surprises. Toll roads are rare on the island, but if your journey takes you onto tolled routes or private roads, charges might pop up. Roadside assistance is another often-overlooked extra; it’s worth checking if it’s included or if you’ll face steep fees should you need help near Deia or Valldemossa. Going prepared and clarifying all terms before signing can help you enjoy the island’s beaches and mountain villages without any financial setbacks.
