Los Realejos, Canary Islands, Spain: Submarine Cable Landing Point

Los Realejos is a municipality in the northern part of Tenerife, the largest island in the Canary Islands archipelago, forming part of Spain's province of Santa Cruz de Tenerife. Situated close to Tenerife's north coast, it serves as a landing point for submarine cable infrastructure connecting islands within the Spanish Canary Islands chain. One submarine cable currently lands at Los Realejos, linking it to the broader inter-island connectivity framework of the archipelago.

The cable landing at Los Realejos supports an inter-island corridor within Spain, connecting Tenerife to the island of La Palma. This places Los Realejos within a network of Canary Islands landing points that together maintain submarine connectivity across the archipelago, complementing the terrestrial infrastructure of individual islands with dedicated undersea links.

Cables Landing at Los Realejos

Tenerife-La Palma (draft) is the sole submarine cable landing at Los Realejos. As its name indicates, this cable connects Tenerife to La Palma, both islands forming part of the Canary Islands and falling within Spanish territory. The cable is currently listed at draft status, indicating it is at a planning or development stage rather than being fully operational. No length or ready-for-service date has been confirmed at this stage.

Regional Context

Within Spain's network of submarine cable landing points, Los Realejos hosts one cable, placing it among the more modestly connected landing points in the country. Spain's submarine cable infrastructure spans 34 cables across 46 landing points, and several other Spanish landing points host considerably more cables, including Alta Vista, Granadilla de Abona, and Santa Cruz de La Palma in the Canary Islands, as well as Barcelona, Bilbao, and Valencia on the Spanish mainland, each of which serves three cables. Within the Canary Islands specifically, Los Realejos is one of a number of landing points that collectively provide inter-island and wider international submarine connectivity for the archipelago.

Network Role

Los Realejos functions as a single-cable terminus, with its current infrastructure dedicated to the inter-island corridor between Tenerife and La Palma. Once the Tenerife-La Palma cable reaches operational status, it will provide a direct submarine link between these two Canary Islands, supplementing whatever aerial or existing submarine routes currently serve this connection. This role is specifically intra-Spanish in character, reinforcing connectivity within the archipelago rather than extending links to other countries.

In the broader Spanish submarine cable graph, Los Realejos represents a developing node focused on inter-island resilience within the Canary Islands. Its position on the northern coast of Tenerife, alongside other Canary Islands landing points, contributes to the distributed architecture through which the archipelago maintains submarine connectivity across its constituent islands.
