Castro Marim City Car Hire

Castro Marim is a historic border fortress in eastern Algarve, located right at the Spanish border by the Guadiana River, 4 km from Ayamonte in Spain and 50 km east of Faro. With one rental agency in the city center, the selection is limited, but the location is unique for those wanting to explore the borderland between Portugal and Andalusia. Reserva Natural do Sapal de Castro Marim offers one of the Algarve's best nature experiences.

Castro Marim's medieval castle dominates the city skyline and offers views over the Guadiana River and Spain. The Sapal de Castro Marim nature reserve, directly south of the city, is home to flamingos and numerous wading birds. Vila Real de Santo António lies 5 km to the south at the river mouth.

Drive to Vila Real de Santo António and take the ferry across the Guadiana to Ayamonte in Spain – a 10-minute experience.
