Montaña Amarilla, Tenerife: Volcanic Formations and Reef Life

Montaña Amarilla stands as a protected marine reserve, characterized by its striking yellow and orange volcanic rock formations that extend below the surface. This site, located in the Costa Del Silencio area, presents a unique geological profile with underwater mountains, arches, ledges, and overhangs. The distinctive colour of the volcano's walls continues underwater, creating a visually rich environment that shelters numerous species and offers varied exploration.

The dive profile here typically begins in shallower waters, descending into an intricate world of volcanic architecture. You will navigate through rock formations, discovering natural arches and grottoes that provide shelter for smaller reef inhabitants. The landscape transitions from sandy bottoms to these dramatic structures, with significant pinnacles and lava flows shaping the underwater terrain, making each traverse through its parts a unique exploratory experience.

Below the surface, the site's geology forms a series of natural galleries, tunnels, and canyons. One notable feature is a four-metre-wide cave that allows for easy entry and exit, adding an element of overhead exploration without advanced requirements. These geological features are not merely scenic; they are essential habitats, creating micro-environments suitable for a variety of marine life.

The resident fauna at Montaña Amarilla is diverse, adapting to the complex volcanic structures. You can expect to encounter moray eels (Muraenidae) and garden eels (Heterocongrinae) hidden among the rocks and sand. Octopus (Octopus vulgaris) and cuttlefish (Sepiida) are frequently observed, often blending into the varied textures of the volcanic rock, providing consistent photographic opportunities.

Larger marine species are also present, often moving through the arches and along the deeper sections of the site. Keep an eye out for shoals of fish, including barracudas (Sphyraena barracuda) and various species of rays. Angel sharks (Squatina squatina) can be found resting on the sandy bottom, using their camouflage effectively, while stingrays (Dasyatidae) are also common sightings.

Montaña Amarilla attracts a variety of fish, including trumpetfish (Aulostomus maculatus), parrotfish (Scaridae), scorpionfish (Scorpaenidae), and wrasse (Labridae). Divers can also spot lobsters and spider crabs dwelling within the crevices and under ledges. Occasionally, turtles (Chelonioidea) make an appearance, adding to the site's biodiversity and its appeal as a marine sanctuary.

While the site primarily offers a relaxed dive, suitable for exploring its unique scenery and resident marine life, it also provides access to deeper sections. The maximum depth of 35 metres allows for extended exploration of the underwater mountain’s base and its more intricate grottoes, catering to divers looking to extend their bottom time within no-decompression limits.
