With no people constantly trampling the crests of the dunes, they have recovered their natural shape and curves and appear to have grown taller. This recovery was aided by a project to move tons of sand from the shore to the back of the dunes rather than letting it disappearing into the sea.

The recovery of the dunes, a much visited spot in south Gran Canaria, is a metaphor for the effects of mass tourism on Gran Canaria's environment and natural spaces. 

As Gran Canaria confronts the most serious crisis in its 60 years as a major tourist destination, many people are asking whether we will ever return to days of mass tourism. And whether we even want to. 

With year-round sunshine and natural wonders around every corner, should the new normal be a form of tourism that is compatible with pristine dunes?

Right now, everything is on the table, from a boardwalk across the dunes to a complete rethink of Gran Canaria's tourist industry.
