New book Hidden Beaches Spain details beaches around 5,000km (3,100 miles) of Spanish coastline

Hidden Beaches Spain also reveals which ones are nudist, best for families and perfect for snorkelling
Most of the stunning images in the book were taken by John - and we re previewing some of them below
