Accès et règles
- Gulf of Orosei: the sea caves lie below high cliffs and are reached only by boat; in practice you dive them with a Cala Gonone cave centre (Base One, Protec Sardinia, Argonauta, Bluforia), which provides boat and guide. No marine protected area is in force here yet: an AMP 'Golfo di Orosei–Capo Monte Santu' was being prepared in 2019.
- Bue Marino (Dorgali) and Grotta del Fico (Baunei) are also show caves where tour boats call daily; the Fico is open May–October, tours 10:00–15:30.
- AMP Capo Caccia–Isola Piana (Alghero, 2025 rules): no diving in zone A; zones B/C only with authorisation from the managing body. Unguided diving: daytime, max 4 divers, within 50 m of the buoy, at least a 2nd-level certification. The 15 named underwater caves (Nereo, Falco, Fantasmi, Cervi, Madonnina, Pozzo, Tunnel Azzurro and others) only as guided dives with an authorised centre (guide at least cavern-certified), max 6–10 divers and 3 dives per day per cave; Fantasmi only with a 2nd-level cave certification; training only in the Grotta del Pozzo; no night dives.
- Supramonte: Su Gologone is a natural monument (1998) in a managed site (Società Le Fonti); we found no public diving rules — ask for permission in advance. Sa Oche (Valle di Lanaittu) has paid entry.
Gaz et gonflage
- Gas and rental: Base One (Cala Gonone) fills nitrox, trimix and O₂ and rents CCR cylinders and scooters (Suex XK/XJS). Protec Sardinia runs CCR courses (ask about gas).
Eau et saison
- Water: sea ~22 °C in summer, fresh water in the caves 14–16 °C, halocline around -5 m. After heavy rain the springs flow hard and visibility drops to 1 m or less.
Jour de repos
- Rest day: the Bue Marino and Grotta del Fico show caves, the Su Gologone spring and the Valle di Lanaittu (Sa Oche, the nuraghic village Sa Sedda 'e sos Carros).
