From the coastal highway N-632, head west from Ribadesella 6 km until arriving near the town of Torre. From here, take the paved road 1.8 km to the Vega beach.
A few meters from the eastern end of the beach parking lot, there are outcrops of the limestones of the Gijón Formation, upon which there is a series of alternating limestones and grey marls (Rodiles Formation). The Rodiles Formation, exposed in beds tilted towards the east, contains abundant marine fossils such as brachiopods, belemnites, ammonites, bivaldes, etc.
Above this alternating series there is a one-meter thick layer of conglomerate with siliceous clasts, and then alternating gray sandstones and red mudstones belonging to the Vega Formation. These deposits are fluvial in origin. Approximately 8 m above the conglomerate layer, there is a bed of sandstone tilted about 50º towards the northeast. At the base of this bed there are several tracks of tridactyl bipedal dinosaurs.
