Is Castro Marim right for me?

Castro Marim is an incredibly small, quaint and peaceful town. There are only a handful of restaurants here, and even less bars, which may be too quiet for some. If that’s you, you might want to consider the nearby riverside town of Vila Real de Santo António. It’s also 6.5 km from the nearest beach: Praia de Monte Gordo in Monte Gordo

If quaint and quiet is what you’re looking for, however, Castro Marim could be perfect for you. Although most of the town’s attractions can be seen in a day or even half a day, it is surrounded by a beautiful nature reserve, and its location on the far eastern side of the Algarve is ideal for exploring both Portugal and parts of the SouthWest corner of Spain like the town of Ayamonte and the Marismas de Isla Cristina natural park.

As well as Vila Real de Santo António, other towns in this part of Portugal that are worth visiting include Tavira, São Brás de Alportel, and Faro. The Alentejo, and the Parque Natural do Vale do Guadiana, are also just an hour by car from Castro Marim.

Although there are a lot of places around Castro Marim that are easiest to reach with a car, the town has a train station so it’s one of the Algarve towns that you can explore without a car. From here, you can easily get to Vila Real de Santo António, Tavira, Olhão, and Faro, and then onto the Central and Western Algarve as well. You also don’t need a car to get into Spain: there’s a ferry between Vila Real de Santo Antonio and Ayamonte.
