Most car rental companies in Pamplona require a credit card for the rental. This is used as a security deposit and to cover any additional charges or damages that may occur during the rental period. However, some car rental companies may accept a debit card or cash deposit instead, but additional requirements and restrictions may apply. It is best to check with the specific rental company for their payment policies.

It is recommended to check with the rental company beforehand to confirm their specific documentation requirements.

While it is possible to rent a car in Pamplona without a reservation, it is highly recommended to make a reservation in advance.

It is best to plan ahead and book your rental car in advance.

The fuel policy for rental cars in Pamplona may vary depending on the rental company. Common fuel policies include:

• Full to Full: You will receive the car with a full tank of gas and should return it with a full tank.
• Pre-purchase: You have the option to pre-purchase a full tank of gas and return the car empty. This may be at a slightly higher rate than local pump prices.
• Full to Empty: You will receive the car with a full tank of gas and may return it with an empty tank. You will be charged for the full tank of gas at a higher rate than local pump prices, regardless of how much fuel is used.

It is important to familiarize yourself with the specific fuel policy of the rental company you choose and plan accordingly.
