Ever wish you could travel back in time? Well, now you can, thanks to Limite Zero, a new zipline that connects Sanlucar de Guadiana, in Andalucia, Spain, to Alcoutim, in Algarve, Portugal—which is one hour behind. 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. “It seemed like a great way to unite both places, since a bridge had been talked about for many years, but was never realized,” Jarman says. “Plus, I love a challenge!” Here’s how it works: A 4x4 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, no passport required. (Speeds can reach up to 45 miles per hour.) A short walk takes you to Alcoutim village, where a small passenger ferry awaits anyone who needs a ride back to Spain; fare is included in the 15 euro price.
