La Catedral is a rocky shelf with arches, vaults and caves, where you’ll find a 20-metre-high cave inside. This imposing volcano body, reminiscent of the interior of a cathedral, is located just five minutes by boat from Puerto de la Cruz in the north of the island of Tenerife. Dives are adaptable to all levels and start with a 20-metre descent and an exploration of the intricate topography of the area, reaching depths of 45 metres.
