This beach is placed inside the city, with 400 meters of length and 40 meters of average aproximately width, enjoys all the services; emphasizing its maritime walk that extends across the city. Wharf of Don Luis, it annotates the beach in its left wing, receives the surge of the Cantabrian Sea that accumulates on the wall to change the direction of the waves and to reach the rest of the inlet. Both wings of the sandbank have rocky bottom, which are partially visible with the low tide. Its medium size waves open to both sides, being suitable near the shore. The small tour that the waves reach, between 50 meters and 150 meters, FAVORS the maneuvers.The surge direction determines the behavior of the waves that come to Brazomar. It can arrive almost straightly up to the inlet or from: East or West; to project the waves to the opposite side of the beach. Them begin, the water masses, to form small hills that curl quickly. The water wall that opens the curl is fragmented, by the rocky bottom, demanding concentration and skill in its navigation. When the Sea propitiates the best conditions to navigate, the skilful waves move away considerably from the shore, placing the line of surf in the wings and having a considerably major tour, offering to surfers and wayfarers its better spectacle.
