* ''Playa de Las Canteras'' ('''Las Canteras Beach''') is the largest beach in the city, and is frequented throughout the year by city dwellers as well as by large numbers of foreign visitors. The beach lies on the west side of the isthmus of Guanarteme, which links the peninsula of La Isleta, located to the northeast, with the rest of the island of Gran Canaria. The 3,100 m beach is oriented toward the northwest in what is known as Confital bow or bay, and stretches from the foothills of La Isleta until shortly before the mouth of the ravine Tamaraceite. Along much of this length, the beach is sheltered from most of the waves and currents of the Atlantic by a natural barrier of coral sandstone popularly known as "the bar", which is in easy swimming distance from shore. A system for environmental management has been introduced, and the beach has received ISO 14001 certification – one of only three beaches in Spain to do so, namely La Concha in San Sebastián and La Victoria in Cádiz. Inside the beach runs the Paseo de Las Canteras, a wide pedestrian boardwalk, or sidewalk, which runs parallel to the beach from near the Auditorio Alfredo Kraus to the area known as "Puntilla" until reaching Playa del Confital.  La Playa de Las Canteras covers three areas that correspond to the arches and inflections that it conducts on the coast. Each presents certain morphological characteristics.
