Dive-site story
Archetto takes its name from a natural granite arch that defines the dive route in the Tavolara Marine Protected Area. Divers descend along sculpted rock formations before passing through the scenic swim-through, whose shaded walls are covered in sponges, bryozoans, and yellow cluster anemones. Beyond the arch, boulder fields and sand patches slope away, offering shelter to Mediterranean groupers and schools of bream.

Frequent encounters with resident dusky groupers and brown meagres
