About El Seno
El Seno is a sheltered Pasaia port-mouth boat dive built around rock slabs, an anchor field, and the remains of old shipping traffic. Divers move along a protected inlet edge rather than a wide-open coast, which keeps the outing controlled and scenic while still offering a strong mix of marine life and archaeological interest. It rewards careful buoyancy, a measured pace, and time spent looking into cracks and under slabs.

Community notes to help plan your visit.
Scuba Diving
This is a guided boat dive that rewards slow passes over slabs, anchors, cannons, and the north/south routes through the site.
Freediving
Not a natural freedive target because the site is a managed boat dive with deeper sections and a port-mouth setting.
Snorkeling
Snorkeling is not the right fit; the interesting structure sits at scuba depths.
