Praia dos Cristais, Beach in the coastal region of Galicia, Spain.

Praia dos Cristais is a small sandy beach in the village of Laxe, on the Costa da Morte. Its surface is covered with small, wave-worn pieces of glass that look like multicoloured sand. The beach also has a small slipway that shelters small boats and a stone stage used for cultural events.

The beach's name comes from its past use as a dumping ground for glass objects such as bottles and vases. Marine currents and coastal erosion wore the glass into small rounded pieces that accumulated here, since this stretch is a zone of deposition. The beach also has a small slipway sheltering small boats and a stone stage used for cultural events like the poetic sunset.

The name comes from the glass bottles and vessels once dumped on the sand; wave erosion grinds them into small multicoloured pieces that look like sand. A small stone stage on the beach hosts cultural events such as the poetic sunset (solpor poético).

The beach sits in the village of Laxe on the Costa da Morte, with a small slipway used as shelter for small boats. The Camiño dos Faros long-distance trail passes here on its 4th stage, and a viewpoint and the Insua lighthouse stand nearby.

The "crystals" are not minerals but pieces of glass dumped near the beach in the past; wave erosion rounded them and currents deposited them here, since this stretch is a zone of deposition. The glass was also used to fill the sand.
