Do I need an International Driving Permit (IDP) to rent in Nafplio? Drivers from the US, UK, Canada, Australia, and Gibraltar can usually rent in Nafplio with their national license and passport, while many non-EU drivers outside those groups still need an IDP.

Most economy and compact categories in Nafplio start at age 21, while premium cars, SUVs, and many automatic cars often require age 23 or 25. Younger drivers usually face a surcharge of about €5–€15 per day, and local agencies such as Bounos Car Rental or Aspida Car Rental may apply different limits by model class.
