If you want a memorable Instagram photo, head to the Barranco de Barafonso in east Gran Canaria. Just do it quick before everybody visits the closest thing to Antelope Canyon in the Canary Islands. 

The cobbled old town, with its vast church and squat, heat-proof Canarian houses is the prettiest example of a Gran Canaria hill town in east Gran Canaria. It's well worth a wander.
