Professional Diving Excursion — Alghero, Sardinia
Diving at Capo Caccia: Underwater Caves and Marine Wonders of Northwest Sardinia
Descend into one of the Mediterranean's most celebrated marine protected areas, guided by certified professionals.
This professional diving excursion at Capo Caccia takes certified divers into the submerged and semi-submerged cave systems along Sardinia's northwest coast, departing from the Bay of Tramariglio at the heart of the Protected Marine Area. Guided by experienced, specialized instructors, participants explore remarkable dive sites that are widely recognized for their geological and biological diversity. The experience is designed for divers seeking a technically rewarding and visually striking dive in a protected natural setting.
The Bay of Tramariglio serves as the departure point, and within minutes of boarding a comfortable rigid inflatable boat, divers reach sites that are otherwise inaccessible from the shore. The selection of dive spots adapts daily to current weather and sea conditions, ensuring both safety and the best possible underwater visibility. This flexibility means every dive is tailored to the conditions of the day rather than a fixed route.
Capo Caccia is part of a vast marine protected area where the underwater landscape includes dramatic rock formations, rich Mediterranean fauna, and cave systems that rank among the most distinctive in the world. The dive itself typically lasts between 50 and 60 minutes, though actual bottom time depends on each participant's air consumption. Certified guides remain with the group throughout, maintaining safety standards while allowing divers to experience the site at a measured, enjoyable pace.

This diving excursion departs from the Bay of Tramariglio, located within the Capo Caccia — Punta Giglio Marine Protected Area on the northwest coast of Sardinia, Italy, approximately 25 kilometres from the city of Alghero. The area is recognized as one of the most ecologically significant marine zones in the western Mediterranean, encompassing dramatic coastal cliffs, rich submarine biodiversity, and a network of submerged and semi-submerged caves formed in the local limestone geology. The Capo Caccia promontory rises sharply from the sea and is best known as the site of the Neptune's Grotto cave system, which draws visitors both above and below the waterline. The Marine Protected Area classification restricts industrial and recreational activities, making it an exceptionally well-preserved environment for diving. Alghero, the nearest urban centre, is a historic Catalan-influenced town with direct air connections to mainland Italy and several European cities, making this excursion accessible to international visitors staying along the Riviera del Corallo.
