For centuries, pilgrims, merchants, and even the Kings of Castile and the Lords of Biscay traveled along this ancient royal road that connected Bermeo and Gernika, on their way to the Oath-Bearing Church of Santa Eufemia in Bermeo. The term "royal" refers to the fact that the retinues of successive Castilian monarchs passed through here, having to fulfill the protocol of swearing the charters to receive the title of "Lord of Biscay." This title was inherited by the Castilian monarchy in the 14th century, when Doña Juana Manuela, Lady of Biscay, married Henry II of Castile. Isabella the Catholic in 1483, Ferdinand the Catholic in 1476, and Henry III and Henry IV are some of the monarchs who traveled this "Oath-Bearing Route" through the Lordship. The processions entered Urdaibai via the Gerekiz Pass (Morga) to descend into the Oka valley and celebrate a formal swearing-in ceremony at the Antigua chapel, beneath the Gernika tree. The route ended with another similar celebration at the aforementioned church of Santa Eufemia de Bermeo.

The beach is there only at Ebb and disappears completely under the waves at high tide. From this point you also have a great view of the village of Mundaka

The legend that attributes the name of Mundaca to the Latin expression munda aqua (clean water). This legend appears in the Chronicle of Vizcaya written by Lope García de Salazar in the 15th century. According to this story, a ship from Scotland arrived on the coast of Mundaca carrying a princess who had been banished from her land. The Scots called the place Munda aqua in their Latin language (sic) since they found a very clean source of water that contrasted with the murky waters of the Urdaibai estuary.
