Playa de la Griega, Natural beach in Colunga, Spain

Playa de la Griega is a wide sandy beach on the Asturian coast, where the Libardón River meets the sea and tall cliffs frame the sand on both sides. The beach sits inside a natural bay open to the Atlantic.

The dinosaur tracks lie east of the beach, on a limestone bed tilted slightly toward the sea, about 600 m from the information panel by the river bridge. They record giant quadrupedal sauropods walking on a muddy coastal lagoon roughly 150 million years ago, in the Jurassic, not the Cretaceous. Some prints reach 1.30 m in diameter, among the largest known worldwide.

In July, during the fiestas de Loreto, a jira (picnic outing) is held on the sand, a local gathering that fills the beach with residents of Colunga. The beach is also known as playa de Colunga, and the Catalan sources call it platja de La Cabaña del Mar. The Libardón or Colunga river crosses the sand in a small meander before reaching the Cantabrian Sea.

The beach has showers, restrooms, and a nearby parking area, making a full day visit easy to manage. Lifeguards are present during summer, but outside that season the beach is quieter and has fewer services available.

The sauropod footprints at La Griega reach up to 1.30 metres in diameter, among the largest dinosaur tracks ever discovered worldwide. They lie on a limestone layer tilted slightly towards the sea, about 600 metres east of the beach along a path cut into the hillside.
