About this site
Y-40 is a dive pool at Via Cataio 42 in Montegrotto Terme, Italy, and it is billed as the deepest pool in the world. Divers can descend to 42 metres inside the pool, which is deep for a pool.
The water is thermal and sits at 34°C, far warmer than most open-water sites. Divers enter a heated pool rather than the sea, so the dive takes place in a fixed, enclosed space.
Durable tips from divers — access, hazards, marine life, facilities. For day-of conditions, use the report tool in the conditions card above.
