Marialva

★★★★☆ (7)

Wreckage of the tugboat “Marialva”. Located off the mouth of the Douro River, on a sandy bottom, 25 meters deep. Very damaged and silted. Accessible only by boat.

It is possible to observe pouts, conger eels, octopuses and tub gurnard. Occasionally we can find schools of blue whiting, rays and small-spotted catshark.
