Baia was an elite Roman resort area whose villas and thermal complexes sank due to volcanic bradyseism and rising sea levels—those ruins now form the Parco Sommerso di Baia.

Morning light is best
Book early departures—calmer seas and better visibility typically occur before afternoon winds pick up.

Apply biodegradable sunscreen before getting wet to protect Posidonia beds and submerged mosaics.
Control your fins
Practice neutral buoyancy and fin control to avoid kicking fragile ruins and stirring sediment.
Listen to the guide
Instructors assign routes and explain where it’s safe to observe—follow them to protect both you and the archaeology.
