Quick Details


Discover the D. João de Castro Bank

Banco de D. João de Castro is a large submarine volcano located in the central North Atlantic Ocean, between the islands of São Miguel and Terceira in the archipelago of the Azores. It remains a seismically active zone, lying midway between the islands of São Miguel and Terceira, rising to within 13 metres of the sea surface. The volcano has a large fumarole field, its top approximately 1,600 metres in total. Two parasitic craters, both about 90 by 45 metres wide, are located on the northwest flank. The younger crater displays a floor consisting of a chilled lava lake with polygonal surface fractures, while the older, less distinct crater is obscured by tephra deposits.

Here, in addition to all the fascinating environment that surrounds us, it is possible to encounter large fish such as lilies and wahoos. The manta rays also pass through these waters. Located about 70 miles from Vila Franca do Campo, a three-hour boat trip, this is a full-day program, usually from 7 a.m. to 6.p.m., and includes two dives, some cookies made in the Azores, fruit, and drinking water

This program is available in July, August, and September.
