Just southwest of Ibiza, Spain, lie the uninhabited islets of Es Vedrà and Es Vedranell. Part of a protected nature reserve, these dramatic rock formations are admired for their ecological value and visual impact. Es Vedrà rises around 400 metres straight from the sea, its sheer limestone cliffs resembling a mountain range. Nearby, the jagged outline of Es Vedranell has earned it the nickname "sleeping dragon," appearing to guard its larger sibling.
