Tarifa, Spain

Tarifa, Spain: Submarine Cable Landing Point

Tarifa is a municipality in the province of Cádiz, Andalusia, situated at the southernmost tip of the Iberian Peninsula on the Costa de la Luz. Positioned directly across the Strait of Gibraltar from Morocco, it occupies one of the narrowest maritime passages in the world, making it a natural geographic candidate for submarine cable infrastructure. One submarine cable currently lands at Tarifa, connecting it to the broader Spanish coastal network.

The single cable landing here is the DOS CONTINENTES I & II, a short inter-Spanish system that operates within an exclusively domestic corridor. While Tarifa hosts only one cable at present, its geographic position at the tip of the Iberian Peninsula gives it a distinct character among Spain's submarine cable landing points.

Cables Landing at Tarifa

DOS CONTINENTES I & II is a submarine cable system spanning approximately 95 kilometres, with a ready-for-service date of 2020 (draft status). Both segments of this system connect endpoints within Spain, making it a domestic inter-Spanish cable rather than an international or intercontinental link. The cable's name — meaning "Two Continents" — reflects Tarifa's unique geographic position straddling the boundary between Europe and the proximity of the African continent across the Strait of Gibraltar, even though the cable's other termination points remain within Spanish territory.

Regional Context

Within Spain's submarine cable landscape, Tarifa currently hosts one cable, placing it among the more modestly connected landing points in the country. By comparison, Barcelona leads with three cables, while Alta Vista in the Canary Islands, Bilbao, Candelaria in the Canary Islands, Conil de la Frontera, and Granadilla de Abona each host two cables. Tarifa's connectivity profile at present is smaller in scale than most of its regional peers, though its geographic position at the southern extreme of the Iberian Peninsula distinguishes it within the national network.

Network Role

Tarifa functions as a single-cable terminus in Spain's submarine cable graph, served exclusively by the domestic DOS CONTINENTES I & II system. The cable it hosts does not extend beyond Spanish territory, meaning Tarifa's current role is oriented toward intra-national connectivity rather than international or intercontinental routing. This positions it differently from peer landing points such as Conil de la Frontera, which also sits on Spain's southern coast but may serve broader international corridors.

In the wider regional submarine cable graph, Tarifa represents a geographically significant but presently limited node — a southern Iberian terminus where the proximity to continental Africa is expressed more in geography than in current cable routing, and where the DOS CONTINENTES I & II system anchors a short-haul domestic link along one of the world's most strategically positioned coastlines.
