El Faro, Tenerife: Volcanic Walls and Oceanic Encounters

El Faro is positioned directly in front of the Punta Rasca lighthouse in Tenerife, with access from the shore near the Fuencaliente salt pans to a rocky bay. The initial entry is straightforward, leading you into a sheltered area. As you progress, the volcanic landscape becomes apparent, characterized by dramatic basalt columns forming walls and arches that define much of the site's topography. This unique geological structure sets the stage for the marine life found here, utilizing every crevice and overhang.

The dive typically begins with an anchor on a platform situated at 6 metres, allowing a gradual descent. From this platform, a prominent wall drops to a maximum depth of 20 metres. Along this wall, you'll find natural archways and tubular rock formations, creating a complex environment. These features are not just visually striking; they are critical habitats, often filled with smaller schooling fish like Catalufas (Heteropriacanthus cruentatus) and Sargos (Diplodus sargus), alongside larger Roncadores (Pomadasys incisus) and barracudas.

Exploring the wall further reveals numerous hiding spots for resident species. Keep an eye out for Moray eels (Muraena helena) and Morions (Gymnomuraena zebra) tucked into the basalt formations. Anemones also dot the rock faces, and if you look closely, you might spot Canary slipper lobsters (Scyllarides latus) and various crabs (Brachyura) and cleaner shrimps (Stenopus hispidus) among the crevices, demonstrating the site's rich macrofauna.

Beyond the immediate wall, the site transitions to a sandy seafloor, particularly in the deeper sections. This environment hosts distinct species adapted to the open sand. You can often find Chuchos (Taeniura grabata), a type of ray, and Obispos resting on the bottom. These sand-dwelling species offer a contrast to the wall's inhabitants and add another layer to the site's biodiversity, allowing for different exploratory paths during a single dive.

While much of the activity is focused on the wall and sandy bottom, El Faro, particularly in its southern area near the island's southern tip, can experience pelagic encounters. The winter months are noted for potential sightings of hammerhead sharks (Sphyrna lewini). These encounters typically occur in deeper, more exposed sections away from the main wall, requiring an awareness of the surrounding blue water and a readiness to look beyond the immediate reef.

Currents at El Faro are generally moderate, but they can occasionally strengthen, especially in the more exposed areas towards the southern tip. This variability means divers should be prepared for potential changes in water movement, particularly if venturing away from the sheltered bay. Maintaining good buoyancy control and situational awareness is key to navigating these conditions and fully appreciating the site's diverse offerings.
