Gulpiyuri Beach (Playa de Gulpiyuri)
   This unique inland beach lies in the middle of a grasy field near to the town of Naves, and was formed by a collapsed sink hole in the limestone cliffs, connected to the sea through underground channels. The sandy beach is only 40 meters in diameter and surrounded by cliffs, with shallow crystal clear tidal water and gentle waves. Gulpiyuri maybe a little difficult to find, but with a little help from the locals it is well worth seeking out, but it can also be seen on Google Streetmap using the link below.
