Tacoron, El Hierro: volcanic reefs and garden eel fields

Tacoron is situated directly in front of the natural swimming pools on the southwest coast of El Hierro. The topography is defined by volcanic lava formations that create a steep rocky slope descending from the shoreline. As you move away from the coast, this steepness gives way to a flatter seabed marked by sandy patches at approximately 20 metres. This transition from vertical rock to horizontal sand provides a varied landscape for a relatively short dive profile.

The descent begins on a rugged volcanic structure that offers plenty of texture for close-up inspection. At about 7 metres, you will encounter a natural stone arch that connects the upper reef area toward the shallow swimming pools. This arch serves as a useful landmark for orientation and provides a small sheltered area within the reef. Navigating through the rocky contours and small canyons allows you to explore the intricacies of the volcanic substrate.

The sandy sections of the site are a primary focus, particularly where the seabed levels out. These patches are home to established fields of garden eels that sway with the movement of the water. Moving slowly through these areas allows you to observe their presence without disturbing the sediment. The combination of rocky walls and these soft-bottom sections makes the site suitable for those practicing buoyancy control or looking for specific micro-habitats.

Marine life at Tacoron is diverse despite the shallow depths. You can find several resident species among the rocks and crevices, such as the dusky grouper and various moray eels. Ornate wrasse and parrotfish are frequently seen navigating the reef structure. For those keeping a close eye on the sandy areas, stingrays and garden eels are common sights that define the character of the bottomland.

Larger fish often pass through the area, adding movement to the upper water column. Barracuda and amberjack are known to patrol the edges of the reef, while schools of mullet move through the shallower sections. If you are observant, you might encounter a loggerhead turtle cruising along the slope. These larger animals utilize the volcanic contours for hunting or resting, making the site active even during relaxed dives.

The site is located within the Mar de las Calmas, a sector of the southwest coast recognized for its stable Atlantic conditions. This sheltered position means that currents are generally weak, making the site an ideal location for training or relaxed exploration. While wind and swell can occasionally influence the surface conditions, the underwater environment remains predictable compared to the more exposed sites found elsewhere on the island. This stability is what makes Tacoron a reliable choice for various diver levels.

Visibility at Tacoron is typically high, often reaching between 20 and 30 metres. This clarity allows you to see the transition from the steep volcanic wall down to the sandy plains with ease. The light penetrates well to the maximum depth of 20 metres, enhancing the colours of the reef and the details of the lava formations. This visibility, combined with the calm conditions, provides a clear view of the site's geological features and resident fauna.
