Descend by boat into the Submerged Park of Baia and swim through streets of a drowned Roman resort. This guided Discover Scuba Dive pairs archaeology with marine life in shallow, instructor-led dives suitable for first-timers.
More ways to explore the area's outdoor wonders
You step off the boat and the bay opens beneath you: a mosaic of blue, the hull rocking as sunlight strings through the surface and fragments of marble appear below. An instructor checks your mask, then guides you down—hand in hand—into an ancient city whose streets now host schools of fish.

History
Baia was a Roman high-society resort; repeated bradyseismic events in the Phlegraean Fields gradually submerged its coastal villas and thermal complexes, creating the present underwater park.
Conservation
The park limits anchor damage and restricts access to guided visits to protect mosaics and marine habitats; follow instructor guidance to avoid contact with fragile structures.

Bring a lightweight towel and dry bag
Boat transfers and changing facilities are provided, but a compact towel and dry bag keep gear organized and dry before and after the dive.
Practice ear equalization
Equalize early and often during descent—shallow dives still compress your ears quickly; stop if equalization is painful.
Check visibility and weather
Sea visibility in the Gulf varies with season and swell; confirm local conditions before booking to get better underwater photos.
Stay hydrated and avoid heavy meals
Drink water before the dive and avoid heavy foods right before entry to reduce discomfort and nausea on the boat.
Swimsuit and microfiber towel
Quick-drying items make boarding, diving and changing more comfortable.
