Limestone caves, red coral walls and protected island water on Sardinia's wild northwest edge
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Alghero and Capo Caccia deliver the destination's signature scuba: limestone walls, natural arches, red coral, gorgonians and a deep catalog of cavern and cave routes. Grotta di Nereo is the headline, but open-water choices such as Isola Foradada Punta Timone let mixed-experience teams stay outside a ceiling. Stintino and the Gulf of Asinara add granite reef, canyon and Posidonia scenery, including Secca dell'Ammiraglio, while park-authorized centers run designated Asinara sites. The best trip is local and boat based. Bring proof of certification, expect the guide to substitute sites for wind, and never treat cave reputation as permission. Current Capo Caccia rules require specific authorization and qualifications, and Asinara diving follows its official site table and authorized-operator system.
