History
Baia was a Roman imperial resort; bradyseism from the Phlegraean volcanic system gradually lowered the shoreline and submerged luxurious villas and thermal complexes.
Conservation
The Submerged Park is monitored to protect archaeological remains and seagrass beds; divers are required to follow no-touch rules and operators promote reef-safe practices to limit impact.
Reserve your spot on the Double Dive in the Bay Park for certified divers today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Bring your certification card
You must present an Open Water (or Junior Open Water/Scuba Diver) certification at check-in; digital copies are often accepted.
Watch the weather and sea state
Visibility and swell change with southerly winds — choose mornings for calmer water and better visibility.
Practice buoyancy control
Neutral buoyancy prevents contact with delicate mosaics and reduces silt clouds that impair visibility for everyone.
Use reef-safe sunscreen
Top up on shore with biodegradable sunscreen to protect Posidonia beds and marine life.
Dive computer
Tracks depth and no-decompression limits for safety on two back-to-back dives.
Personal mask and snorkel
A well-fitting mask improves comfort and sighting of archaeological features.
Wetsuit (3–5mm) or 5mm in cool months
Thermal protection depends on season; water can be cool below the surface even in summer.
