Sanlúcar de Guadiana is one of those places even spaniards don’t know if they don’t live around.
It’s a small village at the end of the country but it has something magical I really recommend you to experience.
When you enter the village you can see old white houses typical from Andalusia and, at the end, there’s a small “beach” by the river.
The coolest thing, though, is a zip line that goes from Sanlúcar to Alcoutim, in Portugal. It travels in SPACE and TIME!
It depends a lot on how much you weight, but more or less it goes around 80km/h which means that it takes a few seconds to arrive in Portugal! Cool, isn’t it?
I know it’s not Spain, but once you’re in Alcoutim I totally recommend visiting the white sand beach!
