Buceo Túnel de Garachico

The Garachico Tunnel is one of the most spectacular and challenging dives in northern Tenerife, famous for its volcanic structure and the wealth of wildlife it harbors. Formed by ancient lava flows, this underwater tunnel begins with an access point from the platform, descending vertically to approximately 20 meters. At this point, the tunnel makes a 90-degree turn and becomes a horizontal gallery that progressively widens, with ceilings up to approximately 17 meters high in some places.

The tunnel walls are formed by basalt columns, natural arches, and rock formations that play with the light, creating dramatic backlights when the sun filters through. Inside, especially in the darker areas, species such as crayfish, snails, shrimp, swimming crabs, sea urchins, snake stars, commatulas, planarians, and shade-fish hide. Upon emerging from the tunnel, you can swim outdoors around the volcanic arc that borders the area, completing the dive with open underwater landscapes.

This dive is not for everyone: it requires an experienced diver because it involves depth, darkness, orientation within the gallery, responsibility with light and equipment, and different sensations than typical coastal dives. It is also more affected by waves or currents due to its exposure to the North Atlantic.

What truly sets the Garachico Tunnel apart is its mix of underwater volcanic architecture, twilit fauna, the transition from vertical to horizontal spaces, and the sensation of exploring something more organic, more "sculptural" than just seeing fish. For those seeking diving with character, landscape, structure, and excitement, this spot is one of the most impressive on the island.
