Limite Zero, a new zipline connects Sanlucar de Guadiana to Alcoutim. A privately funded passion project of Englishman David Jarman, the 2,362-foot-long zipline (called “la tirolina” in Spain) crosses the Guadiana River at 50 feet above sea level.
A 4×4 takes you to the departing platform, set near Spain’s San Marco Castle, and in less than a minute, you arrive on the Portuguese side. And since both, Spain and Portugal are a part of the Schengen Zone, there are no customs or immigration controls between the two countries and they have an open border.
