Playa de Las Canteras

About

The Playa de Las Canteras (Las Canteras beach; 'Beach of the Quarries') is the main urban beach of the city of Las Palmas de Gran Canaria, on the island of Gran Canaria in the Canary Islands. It is considered one of the most prominent beaches in the archipelago. The beach operates under an Environmental Management System certified in accordance with the UNE-EN ISO 14001 standard. It has also received certification for universal accessibility for bathing services for people with reduced mobility from the same certifying body. In addition, Playa de Las Canteras has been awarded the “Q for Tourism Quality” flag, the European Union Blue Flag, the ISO Environmental Management Certificate, and the Universal Accessibility Certificate, distinctions that recognize environmental management, service quality, and accessibility standards. In 2013, the beach was ranked tenth in Spain in the “Travellers’ Choice Playas” awards, based on a study evaluating 276 beaches across Africa, Asia, the Caribbean, Central America, Europe, the Middle East, and the United States. In that ranking, Playa de Cofete placed sixth in Spain, while Playa de Las Catedrales ranked first nationally. The name of the beach...

Playa de Las Canteras extends along the western side of the Isthmus of Guanarteme, a former strip of dunes and sand that connected the mountains of the La Isleta peninsula, to the northeast, with the rest of Gran Canaria. The beach is the longest of the existing ones in the city. It is the longest beach in Las Palmas de Gran Canaria. Oriented to the northwest, it lies within the bay known as El Confital and stretches for just over three kilometres of fine golden sand, from the foothills of La Isleta to near the mouth of the Tamaraceite ravine.

For most of its length, the beach is sheltered from Atlantic currents by a natural sandstone reef popularly known as “La Barra,” which runs parallel to the shore and can be reached by swimming from the beach. Along the inland edge of the coast runs the Paseo de Las Canteras, a pedestrian promenade extending parallel to the beach from the vicinity of the Alfredo Kraus Auditorium to the area known as La Puntilla, and continuing towards the surroundings of Playa del Confital. The latter area has traditionally been frequented by surfers and bodyboarders and is known for producing a notable right-hand wave.

Playa de Las Canteras comprises three sections corresponding to the arcs and curves formed along its shoreline, each with distinct morphological characteristics.

The northern arc, commonly referred to as Playa Grande, has an approximate length of 1,120 metres. Its width varies from around 20 metres in the southern sector to approximately 120 metres in the central area, and about 80 metres near La Puntilla in the north. This is the most sheltered part of the beach. For much of the year it is protected from wave action by the natural reef barrier (La Barra), and it is further shielded from storms with a north and northeast component by the mountains of the La Isleta peninsula. The principal section of the reef, known as the barra principal or barra grande, is frequently accessed by swimmers from the shore. At low tide, when parts of the reef emerge, various seabirds can be observed resting on it, including groups of gulls. La Puntilla marks the northern end of the beach and is the area where the greatest accumulation of sand occurs, a result of the beach’s natural sediment dynamics, which have been affected by urban development on the isthmus.

The central arc extends for approximately 760 metres. It is about 80 metres wide at its southern end and narrows in the middle section to around 40 metres along its northern side. Within this stretch is a smaller indentation known as Playa Chica, one of the most distinctive areas of Playa de Las Canteras. Playa Chica measures roughly 120 metres in length and, at low tide, reaches a maximum width of about 80 metres at the centre of the arch, narrowing to around 20 metres at its ends. The shoreline in this sector is the rockiest of the beach, with a higher presence of stones and outcrops. As a result, sand transport here is less variable than in the southern arc, and there is generally a net loss of sediment. The central arc is protected by the peña central (central rock), the southern head of the main reef barrier ( barra principal ), and a smaller, separate reef formation known as the barra amarilla (“yellow bar”). Approximately 60 metres from the shore lies the Peña de la Vieja, one of the most well-known rock formations of the beach, measuring about 15 metres in diameter at its base. Other rocky outcrops are also present in this area; many emerge at low tide, while some remain permanently exposed. The gap between the barra amarilla and the barra principal, popularly known as el pasadizo (“the passageway”), is sufficiently deep to allow the passage of small vessels even at low tide. This opening also facilitates the movement of marine fauna between the open sea and the interior waters of the bay.

The southern arc corresponds to Playa de La Cícer, also known as Playa de Guanarteme, and includes the areas of Punta de Núñez and Los Muellitos, located behind the Alfredo Kraus Auditorium. This section extends along approximately 1,080 metres of coastline, with an average width of about 80 metres at low tide. Unlike the northern and central arcs, this area is not protected by La Barra and is therefore more exposed to wave action. Consequently, its beach profile is more variable. The sand is predominantly fine-grained and somewhat more compact than in other sections of Playa de Las Canteras, which reduces the rate at which it is carried offshore. At the southern end, near Los Muellitos, there is a permanent accumulation of pebbles, as well as some stony areas in the central zone near the low-tide line. Punta de Núñez is a rocky outcrop that is directly exposed to the swell affecting the northern sector of the bay. “Los Muellitos” refers to two breakwaters constructed perpendicular to Punta de Núñez, which enclose a small pebble beach approximately 50 metres in length. One of the breakwaters measures about 100 metres in length and the other, located further south, around 60 metres; both are approximately 25 metres wide. Together with La Puntilla at the northern end, these structures form part of the natural and constructed boundaries of Playa de Las Canteras. Approximately midway along the southern arc lies the mouth of the La Ballena ravine, a normally dry watercourse with occasional runoff that reaches the beach during periods of rainfall.

The northern arc, commonly referred to as Playa Grande, has an approximate length of 1,120 metres. Its width varies from around 20 metres in the southern sector to approximately 120 metres in the central area, and about 80 metres near La Puntilla in the north.

La Isleta was originally a separate islet, divided from Gran Canaria by a strait approximately one kilometre wide. To its southeast lay the Isthmus of Guanarteme, a sandy strip that gradually connected La Isleta to the main island, forming the present-day peninsula. The isthmus measured about 4.12 kilometres in length and slightly more than 200 metres at its narrowest point, widening at both ends. Its western margin is occupied by Playa de Las Canteras, while the eastern side is the site of Puerto de La Luz.

The isthmus originally supported an extensive dune field formed by sand deposited by marine currents and subsequently transported inland by the prevailing trade winds. Cartographic records indicate that the dunes remained largely intact until the mid-19th century. Subsequent urban expansion, however, led to their progressive degradation and near disappearance.

Although the isthmus is physically linked to La Isleta, limited geological data are available regarding the precise composition of the materials underlying it. In a 1962 study, the Finnish geologist Hausen proposed that the city of Las Palmas de Gran Canaria is situated on a fluvial terrace composed of phonolitic conglomerates deposited after the Miocene epoch. According to this hypothesis, these materials were carried by the Guiniguada ravine during a period of marine regression associated with increased volcanic activity on the island. During this time, La Isleta is thought to have emerged as an islet as a result of volcanic eruptions that continued into the Quaternary period.

Marine currents flowing between La Isleta and Gran Canaria initially hindered the consolidation of the strait. Over time, however, successive fluvial deposits and the accumulation of calcareous sediments from abundant marine fauna—particularly shell fragments and oyster beds—contributed to cementation processes. The gradual infilling of the channel ultimately produced a tombolo, forming the Isthmus of Guanarteme and permanently linking La Isleta, now a peninsula, to the rest of the island.

The original tombolo formed a beach whose shoreline extended approximately to the present location of La Barra, the natural reef that runs parallel to Playa de Las Canteras. Freshwater runoff from the La Ballena ravine may have contributed to the compaction and lithification of beach sediments, leading to the formation of the rock substrate visible today. Over time, wave action and prevailing winds shaped La Barra and the adjacent rocky outcrops into their current forms.

Historically known as Bahía del Arrecife, Playa de Las Canteras consists predominantly of fine, light-coloured sand. The sediment contains small crystals of olivine and pyroxene, as well as organic components derived from fragmented shells, locally referred to in the Canary Islands as confite. At low tide, rocky outcrops emerge from the water, likely corresponding to the underlying substrate upon which both the beach sands and the isthmus are deposited.

In the background, the volcanoes of La Isleta, with the first houses of the neighborhood that bears its name extending at their feet.

The former dune and sand strip that constituted the Isthmus of Guanarteme has largely disappeared. Today, only Playa de Las Canteras to the west and Playa de Las Alcaravaneras to the east remain as partial remnants of what was once an extensive dune system.

At the end of the 19th century, the previously sparsely populated area began to experience development, stimulated in part by the growth of Puerto de La Luz. Housing gradually spread across the dune field, eventually consolidating the urban neighbourhood of Santa Catalina.

Urban construction altered the natural circulation of sand driven by wind and marine processes. As buildings obstructed the movement of sand inland, sediment accumulated and contributed to changes in the configuration of the isthmus.
