At just 3.2 metres long and 1.45 metres wide, the Ponte Internacional do Marco is, according to several international sources, the smallest international bridge in the world. Built of wood over the Ribeira de Abrilongo, it connects the Portuguese village of Várzea Grande (parish of Esperança, municipality of Arronches, district of Portalegre) to the Spanish village of El Marco (municipality of La Codosera, Extremadura). Just walk across it to change country — and time zone, since mainland Portugal is one hour behind Spain.
What Is the Ponte Internacional do Marco
The current bridge, built of wood with funding from the European Union and labour from both sides of the border, was inaugurated in 2008, replacing a rudimentary crossing that was frequently washed away by flooding on the Ribeira de Abrilongo — the stream that, at this point, forms the natural border between the two countries. The bridge only allows pedestrians, bicycles and motorcycles to cross: its small size rules out cars. At each end stands a stone marker identifying the country: a "P" on the Portuguese side, an "E" (for España) on the Spanish side.
How to Get There and Visit
The bridge is about 10 minutes by car from the centre of Arronches, and around 30 minutes from Portalegre and Elvas. There's no formal parking next to the bridge, so most visitors leave the car nearby and walk the last stretch along the rural road that serves Várzea Grande. The visit itself takes only a few minutes, but it's a popular stop for anyone who enjoys geographic curiosities — crossing two or three steps and changing country (and time) is a rare experience anywhere in Europe.
River Beaches Near the Ponte Internacional do Marco
The area around Arronches and Marvão, in the Alto Alentejo, has several river beaches that pair nicely with a visit to the bridge, especially during the warmer months.
Praia Fluvial de Fronteira
The closest to the bridge, about 20-25 minutes by car. Located in the village of Fronteira, it makes use of the calm waters of the Ribeira Grande next to the Barragem da Apartadura — a peaceful option, good for families. See the full Praia Fluvial de Fronteira guide.
Praia Fluvial da Portagem
About 35-40 minutes from the bridge, on the Sever river, next to the historic walled village of Marvão. It's considered one of the most beautiful river beaches in the Alto Alentejo and sits between two old bridges in the village of Portagem. It pairs well with a visit to Marvão, perched more than 860 metres above sea level. Find out more in the Praia Fluvial da Portagem guide.
Praia Fluvial do Alamal
The furthest of the three, about 55 minutes away, on the river Tejo, facing the Castelo de Belver, in the municipality of Gavião. It's often named as one of the best river beaches in Portugal, with full facilities including a bar, restaurant and watersports equipment rental. Details in the Praia Fluvial do Alamal guide.
Where to Stay
For anyone wanting to extend the trip, Marvão is the most practical base in the region, with views over the Alto Alentejo and, on clear days, as far as Spain. The historic Pousada Marvão, set in the centre of the walled village, and the Sever Rio Hotel, by the river in Portagem, are two accommodation options near the Praia Fluvial da Portagem.
A One-Day Itinerary
A suggested route for exploring the region in a single trip: Ponte Internacional do Marco → the village of Arronches → Praia Fluvial de Fronteira → the historic village of Marvão → Praia Fluvial da Portagem to end the day. It's an itinerary that combines a unique geographic curiosity, historical heritage and two of the best swimming spots in the Alto Alentejo.
